Remove the additional load
Perform troubleshooting
Prolong the acceleration time
Adjust the manual boost torque or
V/F curve
Adjust the voltage to normal
range
Select start upon rotational
velocity follow up or start upon
motor shutdown
Err02
Check if the output loop of the
inverter is earthed or short circuited
If the acceleration time is too short
If the manual boost torque
or V/F curve is proper
If the voltage is too low
If the rotating motor is started
If load is added suddenly
during the acceleration
The inverter modelis
rather small
