What causes too large speed deviation in JACT Inverter?
If your JACT Inverter experiences Too large speed deviation, it could be due to: * The encoder parameters being set incorrectly; set the encoder parameters properly. * The motor auto-tuning not being performed; perform the motor autotuning. * F9-69 and F9-70 being set incorrectly; set F9.69 and F9.70 correctly based on the actual situation.
How to fix overcurrent during deceleration on a JACT AT580 Inverter?
If your JACT Inverter shows overcurrent during deceleration, it could be due to: * A grounded or short-circuited output circuit. Eliminate any external faults. * Motor auto-tuning not being performed. Perform the motor auto-tuning. * A deceleration time that's too short. Increase the deceleration time. * Incorrect voltage. Adjust the voltage to the normal range.
Why is my JACT AT580 showing overvoltage during deceleration?
If your JACT Inverter is showing an overvoltage during deceleration, it may be because: * The input voltage is too high; adjust the voltage to the normal range. * An external force is driving the motor during deceleration; cancel the external force or install a braking resistor. * The deceleration time is too short; increase the deceleration time. * The braking unit and braking resistor are not installed; install the braking unit and braking resistor.
What to do if my JACT Inverter shows overcurrent during acceleration?
If your JACT Inverter shows overcurrent during acceleration, it could be due to several reasons: * The output circuit might be grounded or short-circuited; in this case, eliminate any external faults. * Motor auto-tuning may not have been performed; perform the motor auto-tuning. * The acceleration time might be too short; increase the acceleration time. * Manual torque boost or the V/F curve might not be appropriate; adjust these settings. * The voltage could be too low; adjust the voltage to the normal range. * The startup operation may have been performed on a rotating motor; select rotational speed tracking restart or start the motor after it stops. * A sudden load may have been added during acceleration; remove the added load. * The inverter model might be of too smal...
Why are the X terminals disabled on my JACT AT580?
If your JACT Inverter is showing that the X terminals are disabled, it could be due to: * The parameters being set incorrectly; check and reset the parameters in group F4. * The external signal being incorrect; re-connect the external signal cables. * The jumper bar across OP and +24 V becoming loose; re-confirm the jumper bar across OP and +24 V. * The control board being faulty. Contact the agent or JACT for technical support.
What causes EEPROM readwrite fault in JACT AT580 Inverter?
If your JACT Inverter reports an EEPROM readwrite fault, it means that the EEPROM chip is damaged. Replace the main control board.
What does “ Err23 ” displayed at power-on mean for JACT Inverter?
If your JACT Inverter displays “ Err23 ” at power-on, it could be caused by: * The motor or the motor output cable being short-circuited to the ground; measure the insulation of the motor and the output cable with a megger. * The inverter being damaged. Contact the agent or JACT for technical support.
What causes Err14 (module overheat) fault to be reported frequently on a JACT Inverter?
If your JACT Inverter reports “Err14 (module overheat) fault is reported frequently”, it could be due to: * The setting of carrier frequency is too high; reduce the carrier frequency (F0.15). * The cooling fan is damaged, or the air filter is blocked; replace the fan and clean the air filter. * Components inside the inverter are damaged (thermal coupler or others). Contact the agent or JACT for technical support.
What does it mean if my JACT Inverter reports load becoming 0?
If your JACT Inverter reports a load becoming 0, it indicates the inverter running current is lower than F9.64. Check that the load is disconnected or the setting of F9.64 and F9.65 is correct.
What causes a communication fault in a JACT AT580?
If your JACT Inverter has a communication fault, it could be due to: * The host computer being in an abnormal state; check the cabling of the host computer. * The communication cable being faulty; check the communication cabling. * F0.28 being set improperly; set F0-28 correctly. * The communication parameters in group FD being set improperly; set the communication parameters properly.
