Invalid variant

What does E46.2 mean?

The installed safety option variant is incompatible with the inverter type, or an incorrect variant (e.g., with an encoder interface on a double axis system) has been plugged in. This prevents the safety functions from operating and inhibits the output stage, requiring immediate correction for functionality.

Complete Troubleshooting Guide

1. 1

   Remove the currently installed safety option from the drive.

2. 2

   Ensure the correct safety option variant, compatible with the inverter type and application requirements (e.g., without an encoder interface for double axes), is installed.
