E18—-Error of motor angle testing

(Motor angle error when running)

Error solution steps
Whether the motor in correct angle; Check the monitoring interface of operation panel dj [check whether the motor angle within 252 ±5] [Big deviation of motor angle will cause overcurrent or over speed when motor is  accelerating or sudden stop]
Whether the grating is loose or not, whether it touch or interfere the sensor on encoder board.
Check the encoder whether it is dusted.
Pin of power plug  1X4 is come off, it will cause mistake of three phase.
Other steps same as E8.
