Control power
supply fault
Err08
1. The input voltage is not within
the allowable range.
2. The input voltage is not
stable, causing the bus voltage
to jump frequently around the
undervoltage threshold.
1. Adjust the input voltage to
the allowable range.

after power failure until the
input voltage becomes normal,
and then power on the AC
drive again.
Undervoltage Err09
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.

5. The drive board is faulty
6. The main control board is
faulty.
1. Reset the fault.
2. Adjust the voltage to normal
range.
3. Contact the agent or
Inovance.
AC drive
overload
Err10
1. The load is too heavy or
locked-rotor occurs on the motor.
2. The AC drive model is of too
small power class.
1. Reduce the load and check
the motor and mechanical
conditions.
2. Select an AC drive of higher
power class.
