Safety Hardware

What does F111 mean?

A malfunction in the safety input enable hardware has been detected, specifically that one of the required safety inputs (S1 or S2) is not enabled. This indicates a problem within the drive's integrated safety circuit or incorrect external safety wiring, preventing safe operation.

Complete Troubleshooting Guide

1. 1

   Check the status of all safety input signals (e.g., S1, S2) and associated external safety devices (e.g., E-stops, safety relays) to ensure they are properly enabled and providing the correct voltage/signal.

2. 2

   If safety functionality is not being utilized, verify that the required jumper for I/O terminals S1, S2, and S+ is correctly installed and securely tightened to bypass the safety circuit.

3. 3

   Inspect wiring to the safety inputs for breaks, loose connections, or damage.

4. 4

   If the fault persists after verifying inputs and jumpers, replace the control module as the safety hardware may be internally faulty.
