Default Setting No. Default Setting Data Change No. Setting a value higher than the rated value of the device to be driven may damage the motor or machine. Match the device rating when setting this function. F04 Base frequency 1 F 0 4 BAS E Hz — 1 Setting range 25 to Hz This function sets the maximum output frequency in the constant torque range or the output frequency at the rated output voltage. Match the motor rating.
Note: If the value of Base frequency 1 is set higher than that of Maximum output frequency 1, the output voltage does not increase to the rated voltage. The maximum frequency limits the output frequency. Acceleration and deceleration times are represented by the three most significant high-order digits.
Set acceleration and deceleration times with respect to maximum frequency. Note that a voltage greater than the supply input voltage cannot be output. Value 0 terminates operation of the voltage regulator function, thereby resulting in the output of a voltage proportional to the supply voltage.
Note: If the value of Rated voltage 1 is set higher than Maximum output voltage 1, the output voltage does not increase to the rated voltage. The maximum output voltage limits the output voltage. Set frequency The actual operation time differs from the set value. Insufficient magnetic flux of the motor due to a voltage drop in the lowfrequency range can be compensated. Setting Range Characteristics Selected 0. When a general-purpose motor is selected, the operation level is lowered in the low speed range according to the cooling characteristics of the motor.
Enter a value from 1 to 1. Check the characteristics of the driven motor. This function selects operation if a momentary power failure occurs. The function for detecting power failure and activating protective operation i.
The automatic restart function for automatically restarting a coasting motor without stopping when the supply voltage is recovered can also be selected. Set Value Function Name Operation at Power Failure Operation at Power Recovery 0 Inactive intermediate drive trip 1 Inactive drive trip at recovery If undervoltage is detected, the drive will immediately trip and an undervoltage fault LU is displayed.
The drive output stops and the motor will coast to a stop. If undervoltage is detected, the drive output stops and the motor will immediately coast to a stop. A drive fault is not activated. The drive operation is not automatically restarted.
Input a reset command and operation command to restart. An undervoltage fault LU is activated at power recovery. Drive operation is not automatically restarted. Input a reset command to restart operation. The drive collects the inertial energy of the load to maintain the DC bus voltage and controls the motor until it stops, then an undervoltage fault LU is activated.
The drive will automatically decrease the deceleration time if necessary. If the amount of inertial energy from the load is small, and the undervoltage level is achieved before the motor stops, the undervoltage fault is immediately activated and the motor will coast to a stop. When the DC bus voltage reaches the operation voltage level H15 , energy is collected from the inertia of the load to maintain the DC bus voltage and extend the ride-through time.
The drive will automatically adjust the deceleration rate to maintain DC bus voltage level. If undervoltage is detected, the protective function is not activated, but drive output stops and the motor coast to a stop. If undervoltage is detected, the protective function is not activated. If undervoltage is detected, the protective function is not activated, but drive output stops. Input a reset command and operation command to restart operation. Operation is automatically restarted.
For power recovery during ride-through, the drive will accelerate directly to the original frequency. If undervoltage is detected, operation automatically restarts with the frequency selected at the time that the undervoltage was detected.
Operation is automatically restarted with the frequency selected at the time of power failure. Note: Function codes H13 to H16 are provided to control a restart operation after momentary power failure. These functions should be understood and used. The pick-up speed search function can also be selected as a method of restarting when power is recovered after a momentary failure. For setting details, see function code H The pick-up function searches for the speed of the coasting motor to restart the motor without subjecting it to excessive shock.
In a high-inertia system, the reduction in motor speed is minimal even when the motor is coasting. A speed search time is required when the pick-up function is active. In such a case, the original frequency may be recovered sooner when the function is inactive and the operation is restarted with the frequency prior to the momentary power failure. The pick-up function works in the range of 5 to Hz.
If the detected speed is outside this range, restart the motor using the regular restart function. The operation follows the figure below.
The drive output starts with the start frequency when operation begins, and stops with the stop frequency when operation ends.
If the upper limit value is less than the lower limit value, the upper limit value overrides the lower limit value. Operation follows the figure below. The starting frequency can be set to reserve the torque at startup and can be sustained until the magnetic flux of the motor is established. Reducing the set value adversely affects the output current waveform i. For example, at 0. Use this function as required. The amplitude of the output can also be adjusted. The operation will not start if the starting frequency is less than the stopping frequency or if the set frequency is less than the stopping frequency.
F26 Motor sound carrier frequency F 2 6 MTR SOUND This function adjusts the carrier frequency to prevent resonance with the machine system, reduce motor and drive noise, and also reduce leakage current from output circuit wiring. This operation enables the drive to continue operation under the limit even if a sudden change in load torque occurs. Limits are set for driving torque and braking torque.
When this function is activated, acceleration and deceleration operation times are longer than the set values. The machine should be so designed that safety is ensured even when operation does not match the set values. Assign values 0 to 2 to the target digital input terminal. The combination of input signals determines the frequency.
Note: Values which are not set in the functions from E01 to E05 are assumed to be inactive. To use this HLD terminal function, assign 6 to the target digital input terminal. An alarm signal is neither output nor self-held. To use this BX terminal function, assign value 7 to the target digital input terminal. DC injection brake command DCBRK Value 8: This function is used for DC Brake time control by digital input including extending braking operation during stopping as well as during start up into a rotating load.
The DC injection braking continues while the digital input signal is on. Disconnecting them clears the trip indication and restarts operation. To use this RST terminal function, assign value 5 to the target digital input terminal. This function is used to protect an external brake resistor and other components from overheating. To use this THR terminal function, assign value 9 to the target digital input terminal.
ON input is assumed if this terminal function is not set. The motor is then directed to drive operation. The change ranges from 0 to maximum frequency. Operation in the opposite direction, of the operation command is not allowed. Select the desired type by setting the frequency F01 or C Edit permission command data change permission WE-KP data protection Value This function allows the data to be changed only when input is received from an external signal, thereby preventing function code data changes.
To change data, turn the terminal on and change its setting to another number. Input Signal Selected Function 15 [Related Function: F01] off Normal operation if normal operation is set and vice versa on Inverse operation if normal operation is set and vice versa Interlock Value When a contactor is installed on the output side of the drive, the contactor opens at the time of a momentary power failure. This prevents the reduction of the DC circuit voltage and may prevent the detection of a power failure and a correct restart operation after power is recovered.
The restart operation, in the event of a momentary power failure, can be performed effectively with power failure information provided by an external digital input signal. Select the command source in HLink function and assign 17 to the target digital input terminal to enable or disable commands in this input signal state. This input terminal is only used to check for an incoming input signal through communication and does not affect drive operation.
ON input is assumed when this terminal function is not set. Local operation command LOC Value 20 : Frequency and operation command from the Keypad can be enabled when this is turned on close. To use LOC terminal function, assign value 20 to the target digital input X inputs. Forward command2 Value 21 : This is the alternate Forward command.
To use the Forward command 2 terminal function, assign 21 to the target digital input X input. Reverse command2 Value 22 : This is the alternate Reverse command. It is selected from the terminal by the Operation command2 Operation command1 switch. To use the Reverse command 2 terminal function, assign 22 to the target digital input X input. Stopping due to undervoltage LV Value 3: If the undervoltage protective function activates, i.
The signal goes off when the voltage recovers and increases above the detection level. The ON signal is retained as long as the undervoltage protective function is active. Undervoltage detection level: V series: V V series: Torque limiting TL Value 4: When torque limiting is active, the stall prevention function is automatically activated to change the output frequency. The torque limiting signal is output to lighten the load and also used to display overload conditions on the monitor device.
This ON signal is output while the current or torque is limited or power regeneration is prevented. Restart after momentary power failure IPF Value 5: Following a momentary power failure, this function reports the start of restart mode, the occurrence of an automatic pull-in, and the completion of the recovery operation. Following a momentary power failure, an ON signal is output when power is recovered and a synchronization pull-in operation is performed. The signal goes off after a frequency level equal to that prior to power failure has been recovered.
For 0 Hz restart at power recovery, no signal is output because synchronization ends when power is recovered. The frequency is not recovered to the level before the power failure occurred. For setting procedure, see E33 Overload early warning operation selection and E34 Overload early warning operation level. An ON signal is output when the DC injection brake function is operating. The drive is ready to operate after the main circuit and control circuit power have been established where the drive protective function is not activated.
About one second is required from power-on to ready for operation under normal conditions. When a stop command is entered, the signal goes off after drive output stops. When a coast-to-stop command is entered, and the drive protective function is operating, the signal goes off immediately. This function serves only to turn the transistor output on or off through communication and is not related to drive operation.
When the set value is 1, contacts Y5A and Y5C are connected when the drive control voltage is established about one second after power on. If the output frequency exceeds the set operation level, an ON signal can be output from terminals Y1 to Y5. Hysteresis width : 0. Load and line speed Use display coefficient A. Therefore, values smaller or larger than this range are limited to a minimum value of 0.
Sets the time from when the operation level is attained until the overload early warning function is activated. When the output torque is lower than the level setting E36 for longer than the time setting E37 , the Underload signal will be active.
It can be monitored with a transistor output E20, E21 or relay output E24 by setting value In E44 LED monitor display at stopping , specify whether to display selected items or the same items as during running.
Value 0 1 Set value: 0 During running Display at frequency setting When a set frequency is checked or changed by the keypad, the value shown below is displayed. Select the display item by using E43 LED monitor display selection. This display is not affected by E44 LED monitor display at stopping. Increase the set value to raise contrast and decrease to lower contrast. Up to three jump points can be set. This function is ineffective if jump frequencies 1 to 3 are set to 0 Hz.
A jump does not occur during acceleration or deceleration. If a jump frequency setting range overlaps another range, both ranges are added to determine the actual jump area. Setting range: 0 to Hz In 0. See E01 to E05 for terminal function definitions. Setting range: 0, 1, 2 This function determines the frequency setting method. C31 Analog input bias adjustment The setting range is C32 Analog input gain adjustment The gain adjustment range is 0.
For details, see the explanation for F17 and F This function adjusts the time constant of the input filter to remove the effects of noise. A value that is set too large delays control response although stabilizing the control. A value that is set too small speeds up control response but renders the control unstable. If the optimum value is not known, adjust the setting if the control is unstable or response is delayed.
Note: The set value is commonly applied to Terminals 12 and C1. If this setting is not made, an incorrect motor speed synchronous speed is displayed on the LED. This setting should only be changed when driving a motor with a different capacity.
Set the nominal motor capacity listed in Standard Specifications. A value in the range from two ratings lower to one rating higher than the nominal motor capacity can be set. If a value outside this range is set, accurate control cannot be guaranteed. If a value between two nominal motor capacities is set, data for the lower capacity is automatically stored for related function data. If this function setting is changed, the following related functions are automatically set to data values for the Fuji 3-phase standard motor.
Some typical examples are listed below. Auto tuning improves control and calculation accuracy. Tuning Procedure 1. Adjust the voltage and frequency according to motor data. First enter motor constants that cannot be tuned. When tuning the no-load current, beware of motor rotation. Tuning will start. Tuning may take several seconds.
The total tuning time varies depending on the settings for acceleration and deceleration time. Press the STOP key, and the procedure will end. Beware of motor rotation as injury may result. On-line tuning minimizes speed changes related to these temperature changes. The slip compensation control adds a frequency, proportional to motor torque, to the drive output frequency. This will minimize variations in motor speed due to changes in torque.
When connecting a reactor or filter to the output circuit, add its value. Use value 0 for cable values that can be ignored. The values for all functions are initialized. The set value in H03 automatically returns to 0 following the end of initialization. The machine should be designed to ensure safety during a restart.
When the retry function is selected, GE start software F02 set 3 or 4 does not work. Setting range: Count : 0, 1 to 10 Waiting time : 2 to 20 seconds When a drive protective function which invokes the retry operation is activated, these functions release operation of the protective function and restarts operation without issuing an alarm or terminating output.
If the cause of the alarm has been removed at this time, the drive starts without switching to alarm mode. If the cause of the alarm still remains, the protective function is reactivated according to the wait time set in H05 Retry waiting time.
This operation is repeated until the cause of the alarm is removed. The restart operation switches to alarm mode when the retry count exceeds the value set in H04 Retry count. The operation of the retry function can be monitored from terminals Y1, Y2 and Y5. While power is applied to the drive, the automatic fan control detects the temperature of the heatsink and turns the fan on or off. When this control is not selected, the cooling fan rotates continuously. The cooling fan operating status can be monitored from terminals Y2 and Y5.
Curvilinear Acceleration and Deceleration This function is used to minimize motor acceleration and deceleration times in the range that includes a constant output range. At startup, this function detects the motor speed and outputs the corresponding frequency, thereby enabling a shock-free motor startup. The normal startup method is used if the coasting speed of the motor is Hz or more as a drive frequency and if the value of F03 Maximum frequency exceeds the value of F15 Frequency limiter upper limit.
Note: To use this function, execute PO4, page This function is effective if F14 Restart after momentary power failure operation selection is set to 3, 4, or 5.
This function is also effective when operation is switched from the line to the drive. The motor is started with the same frequency as the current coasting speed speed search. In addition to restarting following a momentary power failure and switching between the line and the drive, this function detects the coasting speed of the motor and starts the motor at the same frequency as all startups including when an ON operation command is entered.
H08 0 t [sec] Rev. This function prevents a reversing operation resulting from a connection between the REV and CM terminals, inadvertent activation of the REV key, or negative analog input from Terminals H10 Energy-saving operation H14 Auto-restart freq. If used for a constant torque load or rapidly changing load, this function causes a delay in control response.
The energy-saving operation automatically stops during acceleration and deceleration or when the torque limiting function is activated. Note: This function is effective only when a STOP command is entered and, therefore, is ineffective if the motor is stopped by lowering the set frequency. Setting range: 0. This function determines the reduction rate of the output frequency for synchronizing the drive output frequency with the motor speed.
This function is also used to reduce the frequency and thereby prevent stalling under a heavy load during normal operation. Note: A frequency reduction rate that is set too large may temporarily increase the regeneration energy from the load and invoke the overvoltage protective function. Conversely, a rate that is too small extends the operation time of the current limiting function and may invoke the drive overload protective function.
Either function starts a control operation if the main circuit DC voltage drops below the set operation continuation level. If power supply voltage to the drive is high, control can be stabilized even under an excessive load by raising the operation continuation level. However, if the level is too high, this function activates during normal operation and causes unexpected motion.
Please contact GE Fuji before changing the factory default value. To rapidly switch power lines, store the remaining voltage attenuation time to wait for the voltage remaining in the motor to attenuate. This function operates at restart after a momentary power failure. If the momentary power failure time is shorter than the wait time value, a restart occurs following the wait time.
If the power failure time is longer than the wait time value, a restart occurs when the drive is ready to operate after about 0. This function sets the time an operation command is to be held in the drive.
If a power failure lasts beyond the self-hold time, power-off is assumed, automatic restart mode is released, and the drive starts operation at normal mode when power is applied again.
This time can be considered to be the allowable power failure time. H19 Active drive H1 9AUT RED Setting range: 0: Inactive 1: Active This function automatically extends accelerating time by 60 seconds or longer to prevent an inverter trip resulting from a temperature rise in the inverter due to overcurrent. If the active drive function is activated, the acceleration time will be three times the selected time. If the values differ, this function produces an output to eliminate the deviation.
In other words, this control matches the feedback amount with the target value. This function can be used for flow control, pressure control, temperature control, and other process controls. The target value can be entered using F01, Frequency setting 1, or directly from the keypad. For entry from F01, Frequency setting 1, input a signal to the selected terminal. For direct entry from the keypad panel, turn on keypad operation. Select any of the digital Terminals X1 E01 to X5 E05 and assign a value of 11 frequency setting switching.
Select a value from the table below according to sensor specifications. Value Description 0 Terminal 12, forward operation, 0 to 10V voltage input 1 Terminal C1, forward operation, 4 to 20mA current input 2 Terminal 12, reverse operation, 10 to 0V voltage input 3 Terminal C1, reverse operation, 20 to 4mA current input Forward or reverse operations can be selected for PID controller output.
This enables motor revolutions to be faster or slower according to PID controller output. Only positive values can be input for this feedback amount of PID control. Negative values e. Feedback signal setting H21 must be different from the type of setpoint value. P-gain operation An operation using an output frequency proportional to deviation is called P operation, which outputs an operation amount proportional to deviation, though it cannot eliminate deviation alone.
I-gain operation An operation where the change speed of the output frequency is proportional to the deviation is called an I operation. An I operation outputs an operation amount as the integral of deviation and, therefore, has the effect of matching the feedback control amount to the target value e. Although an increase in gain speeds up response, an excessive gain causes vibration, and a decrease in gain delays response.
A longer integration time delays response and weakens resistance to external elements. A shorter integration time speeds up response, but an integration time that is too short causes vibration. D-gain operation An operation where the output frequency is proportional to the deviation differential is called a D operation.
It outputs an operation amount as the deviation differential and, therefore, is capable of responding to sudden changes. This control achieves deviationfree, accurate, and stable responses. Proceed as follows: Increase the value of H22 P-gain without generating vibration.
Decrease the value of H23 I-gain without generating vibration. The challenge was to control a permanent magnetic synchronous motor PMSM in open loop and to find a function to stop the machine with PID function in case of input phase loss.
Our solution provides a low voltage ride-through function, a best PMSM control with static pole-tuning at starting, and which has CANopen built-in. This is an installation of diamond wire saw machine for cutting and processing natural stone in quarries, such as granite, marble, slate, onyx, etc.
As well as for industrial materials such as metals, composites, glass, PVC. Now our customer could upgrade and go from a totally manual process with buttons to a more automated and visual process! When doing maintenance on an Uninterruptible Power Supply and its auxiliary equipment, keeping it clean is one of the main objectives. Dirt, dust, sawdust, and metal filings are just some of the pollutants that technicians see in UPSs, even when installed in seemingly clean environments.
These substances can cause failures when they contaminate the contacts of relays and contactors, and conductive material can cause short circuits and malfunctions on printed circuit boards PCBs. At least once a year, make sure your UPS gets cleaned including a good vacuuming with a non-conductive hose and attachments. Never use a blower or compressed air! These methods can blow contaminants deeper into the unit, causing real troubleshooting headaches if and when they finally do cause issues.
Use lint-free rags lightly damp with a nonflammable and fast-drying solvent for heavy deposits, and soft brushes around delicate components and connectors. Always perform cleaning work on equipment that is offline, and de-energized and with the proper personal protective equipment PPE such as goggles, gloves, aprons, and respirators as necessary.
Know Your Pipe and Don't Guess. Know your pipe and don't guess! This includes the customer knowing their liner and its thickness. Many customers don't know their pipe's exact specifications, but by measuring circumference and looking for a schedule embossment on a fitting, as well as referencing a pipe resource is usually a good solution. It is also something they can research with a system engineer ahead of a flow survey or fixed installation. To that point, they could even program the measurement point s on the bench in air conditioning before going in the field.
Optimize Your Inverters. Get Your Installation Right. Surveying the intended installation location for straight run, and selecting a valid installation point is one of the most important tips we could offer. That is after vetting Transit Time Ultrasonic technology for the macroscopic application. This is by far the biggest battle we have in the field, even when we try to get this information upfront in our application work. I would highlight the need for additional straight runs for the plumbing situations that poses the biggest obstacles for us.
The biggest being pumps, two elbows out of plane, valves, and T fittings. The trick is to portray this without evoking fear, just to bring them to conscious thought.
