Switch-on is inhibited

What does A01696 mean?

The drive is unable to switch on and remains in the READY state because its start is inhibited. This can be caused by a deactivated gate driver, an active safety function such as Safe Torque Off (STO), Safe Stop 1 (SS1), or Safe Limited Speed (SLS), or another inhibit condition, preventing motor operation.

Complete Troubleshooting Guide

1. 1

   Verify that no safety functions (STO, SS1, SLS) are currently active and inhibiting the drive's start.

2. 2

   Check the status of the gate driver to ensure it is enabled and operational.

3. 3

   Examine the inhibit bit (r0052.6) in the drive's status words to identify the specific reason for the start inhibition.
