Safety Open

What does F059 mean?

Both of the drive's safety inputs (Safety 1 and Safety 2) are not enabled, indicating an open condition in the external safety circuit. This fault signals that the drive's integrated safety function detects an unsafe state, preventing motor operation until the safety inputs are properly closed and secure.

Complete Troubleshooting Guide

1. 1

   Check the external safety circuit and components (e.g., emergency stop buttons, light curtains, safety gates) to ensure both Safety 1 and Safety 2 inputs are active (closed).

2. 2

   If safety functionality is not being used in the application, 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.
