Controlled by parameter P10-11 motor stall and over-temperature function.

When P10-11=0, the motor is stalled, the actual speed of the motor is less than 10rpm, the torque instruction exceeds the rated torque of the motor, and the duration reaches the motor overheating protection time at the corresponding torque, ER.45 fault will be reported and the machine will be shut down immediately.

View oscilloscope waveforms. The actual speed of the motor is less than 10rpm, and the torque instruction exceeds the rated torque of the motor. Observe whether the motor is stuck by the mechanical structure. A temporary solution. P10-11=1 When the motor is stalled, the torque will become 70% of the rated torque.
