Cause : Z Pulse Correction Error comes when the motor is wired incorrectly or the encoder is wired incorrectly. The setting for the direction of the encoder motor rotation is incorrect

  1. The number of encoder pulses is incorrect.
  2. Set the number of encoder pulses in F1-01 [Encoder 1 Pulse Count (PPR)] correctly.
  3. Do Z Pulse Offset Tuning again.
