E12— motor

(motor overload long time high current operation)

Solution step
1) motor angle is correct; check the operating box monitoring interface in DJ [observe the motor angle is in the range of ± 5 [252] the motor angle deviation is too large, large current or speed phenomenon will accelerate and quick stop]
2) encoder inside is an ash
3) the operator is very frequent pedal, this fault is a frequency too frequently lead to, can put [2] parameter set to 5 relief work frequency
