Possible Causes
1: The output circuit is grounded
or short circuited.
2: Motor auto-tuning is not
performed.
Err04
3: The voltage is too low.
4: A sudden load is added during
operation.
5: The AC drive model is of too
small power class.
1: The input voltage is too high.
2: An external force drives the
motor during acceleration.
Err05
3: The acceleration time is too
short.
4: The braking unit and braking
resistor are not installed.
1: The input voltage is too high.
2: An external force drives the
motor during deceleration.
Err06
3: The deceleration time is too
short.
4: The braking unit and braking
resistor are not installed.
1: The input voltage is too high.
Err07
2: An external force drives the
motor during deceleration.
The input voltage is not within the
Err08
allowable range.
1: Instantaneous power failure
occurs on the input power supply.
2: The AC drive's input voltage is
not within the allowable range.
3: The bus voltage is abnormal.
Err09
4: The rectifier bridge and buffer
resistor are faulty.
5: The drive board is faulty.
6: The main control board is faulty.
1: The load is too heavy or locked-
rotor occurs on the motor.
Err10
2: The AC drive model is of too
small power class.
Maintenance and Troubleshooting
1: Eliminate external faults.
2: Perform the motor auto-
tuning.
3: Adjust the voltage to
normal range.
4: Remove the added load.
5: Select an AC drive of
higher power class.
1: Adjust the voltage to
normal range.
2: Cancel the external force
or install a braking resistor.
3: Increase the acceleration
time.
4: Install the braking unit and
braking resistor.
1: Adjust the voltage to
normal range.
2: Cancel the external force
or install the braking resistor.
3: Increase the deceleration
time.
4: Install the braking unit and
braking resistor.
1: Adjust the voltage to
normal range.
2: Cancel the external force
or install the braking resistor.
Adjust the input voltage to
the allowable range.
1: Reset the fault.
2: Adjust the voltage to
normal range.
3: Contact the agent or
Inovance.
1: Reduce the load and
check the motor and
mechanical condition.
2: Select an AC drive of
higher power class.
