Wrong direction of motor rotation
ACH200 Series High Voltage Variable Frequency Speed Control System Operating Manua
The output voltage has reached the
maximum value, but the current output is
small (motor impedance is large or the
learning frequency is set too large)
Check if the input motor nameplate
parameters are correct
Check if the input motor nameplate
parameters are correct
1. Check whether the input motor nameplate
parameters are correct
2. Whether the motor control mode
selection matches the motor
Re-enter the motor nameplate parameters
Check whether the entered motor nameplate
parameters are correct
1. Check the motor connection, whether
there is a short circuit between phases
2. Check whether the input motor nameplate
parameters are correct
Check if the input motor nameplate
parameters are correct
Check if the input motor rated voltage is
correct
Check if the input motor rated voltage is
correct
motor
no-load
1. Check whether the motor connection is
correct
2. Check whether the PG card is connected
correctly
3. Separate the motor from the machinery
