Over voltage in
acceleration
Err05
1, The input voltage is high
2, The acceleration process there is
an external drag motor running
3, The acceleration time is too short
4, No brake unit and brake resistor
1, Adjust voltage to the normal range
Cancel the additional force or install
braking resistor
3, Increase the acceleration time
4, Install the braking unit or braking
resistor
