SI MM: STOP A initiated

What does 230600 mean?

This fault signifies that the drive-based Safety Integrated (SI) function in the Motor Module (MM) has detected a critical anomaly, initiating a STOP A (pulse suppression via the safety shutdown path of the Motor Module). This can result from an unsuccessful forced checking procedure of the safety path, an internal software error (fault value 1020), or a response to a monitoring channel defect (F30611). This safety-critical fault immediately halts motor operation to prevent hazardous conditions, requiring immediate attention to restore safe functionality.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If fault value is 9999, perform diagnostics for fault F30611, which indicates a defect in a monitoring channel.

2. 4

   Replace the involved Motor Module if the issue persists after initial troubleshooting steps.
