Phenomena
Possible reasons of fault and actions to take
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
running
Frequent fluctuation of load. Decrease the changing
Serious mismatching of rated value of the driver and motor. Set the motor
parameters as actual value.
Frequency setting potentiometer is in bad connect or the frequency setting
signal is in fluctuation. Switch to digit setting mode or increase filter time
constant of analog input signal.
The rotation
direction of motor
is in reverse
Adjust phase sequence of output terminal U, V, W
Set the running direction as reverse (F0.21=1)
Caused by phase loss of output. Check the motor wiring immediately.
