A: 1.check whether the rated parameters of the motor are set correctly. If not, please reset.
2. Check whether the output voltage of the VFD is 460V when the frequency is 60Hz. If not, please adjust the no-load current to the normal status.
3. Check whether the motor has locked rotor, if so, try to eliminate it.
4. Check whether the current displayed on the keypad is consistent with the actual measured current. If it is consistent, it indicates that the motor selection is too small. It is recommended that the customer replace the motor with a higher power.
