这是 MM440 01/06 英文版的对 F0453的说明，现象、对策。

F0453 Motor stalled STOP II
Quit
Refer to F0001
Cause
- up/ or down ramp too steep (excessive gradient)
- inverter connected to an already spinning motor without using the flying restart function
- motor incorrectly connected
- motor too small
- voltage boost P1611 for sensorless vector control too low
Diagnosis & Remedy
Please check the following:
- the motor connections
- increase the ramp-up time P1120 or the ramp-down time P1121
- activate the flying restart function P1200
- use a larger motor
- increase the voltage boost P1611 for sensorless closed-loop vector control
- use closed-loop vector control with encoder instead of sensorless closed-loop vector control.
- activate the V/f closed-loop control mode (P1300 less than 20) instead of closed-loop vector control
