Howoever, when the motor is on/off several times (for example 7 to 13 times), the VFD can't drive the motor to operate again even thought ON signal and speed control signal has been applied to the VFD. No fault and alarm signals are recorded. Any of you encounter this situation before ? How to restart the motor again ? And, I checked that the parameter P1210 is a automatic restart function. Does the problem relate to this parameter ? Thanks. Alex Chan from Hong Kong
