Motor Encoder: Incorrect Enc. Signals (Can Be Cleared in PM)
  • Since the position is no longer generated correctly when this error is detected, the encoder must be re-initialized.
  • When using an incremental encoder with square-wave signals, monitoring is carried out with regard to an inadmissible edge. On the software level, the signals of a resolver are monitored for their levels.
Description:
  • Defective encoder cable or cable shielding
  • Encoder defective
  • Faulty mounting of measuring head in the case of linear measuring systems
  • When operating a motor of ‘IndraDyn MSM’ type: A fault has been detected in the sending telegram of the encoder; telegram failed twice
  • Measuring system dirty
  • Hardware defect on control section of drive
  • Check cable to measuring system and replace it, if necessary
  • Check measuring system and replace it, if necessary
  • Check mounting of measuring head and correct it, if necessary
  • Faults such as an electrostatic discharge to the shaft of the motor may lead to failure of the encoder sending telegram. Prevent faults.
  • Clean or replace measuring system
  • Replace control section or entire drive controller
