The drive is powered off when a fault occurs
WARNING! Wear eye protection to protect your eyes before performing maintenance, repair, or replacement of the drive.
WARNING! Do not restart the drive or run peripherals within 5 minutes when the fuse blows or the leakage circuit breaker trips. Please confirm
the wiring and peripheral machine rating, find out the cause of the trip, if you can not find the reason, please consult the technical support
department, otherwise it will lead to personal accident or damage to the drive.
1. Use an external 24V power supply to power the control loop.
2. Confirm the fault code and the operating status of the drive when the fault occurs via the fault monitoring parameter C01-xx.
3. Refer to the Troubleshooting section to troubleshoot the cause.
Note: 1. By C01-00 [this fault diagnosis information], you can confirm what is the fault and the power is cut off. You can check the status of the drive
(frequency and current) when this fault occurs through C01-01~C01-09. , voltage, etc.).
2. Through C01-10 [Last Fault Diagnosis Information], you can confirm what was the last time the power was cut off. You can check the status of the drive
(frequency, current, voltage) when the last fault occurred through C01-11~C01-19. Wait).
3. When the fault still remains after power-on, please rectify the fault and then reset the fault.
Faults occurred but the drive is not powered off
1. Confirm the fault code displayed on the keyboard.
2. Refer to the chapter on troubleshooting to troubleshoot the cause.
3. Perform a fault reset operation.
Fault Reset
After the fault occurs, to restore the drive to normal, you need to reset the fault after troubleshooting the cause. There are three fault reset methods, namely
1. Press the stop button on the keyboard in the event of a fault.
2. The multi-function input terminal function selects the fault reset and makes the terminal valid.
3. The drive is powered back on.
6.7 Troubleshooting without prompting on the keyboard
When the fault code or error code is not displayed on the keyboard, but the operation of the drive or motor is abnormal, please refer to the contents of this
section and take appropriate measures.
Parameters cannot be modified
Reason
Modify the parameters that cannot be changed during operation when the
drive is running
Modify read-only parameters
Input running command motor does not turn
Reason
Run command given channel is not set properly
Improper setting of the frequency reference mode results in a given
frequency of 0.
Emergency stop signal input
Improper terminal wiring when the terminal is used as a command channel
The given frequency is too low
The direction of motor rotation is opposite to the running command
Reason
Improper wiring of motor cable
The motor's rotation direction is set incorrectly
The motor only rotates in one direction
Reason
Run direction prohibition function
Abnormal motor heating
Reason
Excessive load
Long-term operation at very low speed
Set to vector control mode but no motor self-learning
The cooling fan of the motor is covered with excessive dust, causing the
fan to stall or stop.
Do not run according to the set acceleration/deceleration time
Reason
Excessive load
Countermeasures
Modify the parameter after stopping the drive
Read-only parameters cannot be modified
Countermeasures
Check the F01.01 [Run Command Channel] setting to confirm the running
command given source.
Check the F01.02 [frequency reference mode] setting to confirm that the
frequency reference source is valid.
Release emergency stop signal
Confirm that the control circuit terminal wiring is correct
View the status of the input terminals via C00-14 [Input Terminal Status]
Check if C00-00 [reference frequency] is higher than the set value of F01.13
[lower limit frequency]
Countermeasures
Confirm that the wiring of the drive and motor are correct.
Change the wiring of any two phases of the motor U, V, W
Confirm that the wiring of the drive and motor are correct.
Modify F07.15 [select direction selection] unit position running direction
inversion
Countermeasures
Modify F07.15 [select direction selection] ten-bit running direction
prohibition bit
Countermeasures
Reduce the load
Replace the larger power motor
Change the speed
Replace with drive-specific motor
Motor self-learning
Change the control mode to VF control if possible
Cleaning the fan of the motor
Improve the cleanliness of the environment
Countermeasures
Reduce the load
