An open circuit has been detected in the limit switch wiring, or both limit switches are missing, or they are incorrectly swapped relative to the motor's direction of rotation. This fault prevents proper travel control and triggers an emergency stop.

Complete Troubleshooting Guide

    Check the wiring of all limit switches for open circuits or incorrect connections.

  2. 2

    If limit switches are swapped, correct their connections to align with the motor's direction of rotation.

  3. 3

    Reprogram the affected terminals in the drive's settings if the limit switch configuration needs adjustment.
