CALIBRATE LIMIT SWITCH NOT FOUND ON AXIS {0:A}.

Definition:
During machine calibration, each axis travels to its respective limit switches (the positive or negative limit switch is determined by parameter ________).The axis will stop when the limit switch input is detected by the software. A second limit switch signal is sent to the axis Servo Drive Amplifier which will also stop the axis movement.

This error message indicates that the input signal to the software was not detected but the limit switch input to the servo drive amplifier was detected.

Corrective Actions:
  • Verify that the Servo Drive Amplifier for the axis indicates overtravel alarm in the direction that the axis was moving. If no overtravel alarm is reported, this would typically result in a Following Error alarm.
  • Check the wiring connections at the limit switch for the indicated axis that all four wires are properly terminated.
  • Use the electrical schematics to check the wiring terminations for the software input at the Slice I/O module. Check for continuity. If no continuity then replace harness. If continuity, swap Slice I/O module with another to see if problem goes away (replace Slice I/O module if problem goes away after swap).
