The current limit is set too low. Increase the value.
Over-voltage protection action during decelerating. Increase the decelerating
time.
Improper setting of carrier frequency, too much load may cause oscillation.
The load is too heavy, and the torque is not enough. Increase torque boost value
in V/F mode. If not working, switch to auto torque boost mode, and the motor
parameters should be in consistent with the actual value. If still not working,
switch to flux vector control mode, and check the motor parameters and actual
values to see if they are matched, meanwhile tune the motor parameters.
Mismaching of motor power and driver power. Set the motor parameters at
actual value.
One driver for several motor. Please change the torque boost mode to manual
mode.
The motor can rotate, but speed
regulation can’t be realized.
Improper setting of upper and lower limit of frequency
The frequency is set too low, or the frequency gain is set too low.
Check whether the speed adjustment mode is in consistent with frequency
setting.
Check whether the load is too heavy, whether it is in overvoltage stalled state or
overcurrent limiting state.
Speed changing during motor
Frequent fluctuation of load. Decrease the changing.
