SSI error bit – critical

What does F14.20 mean?

A critical error bit has been set within the SSI protocol from Encoder 2, indicating a severe communication or data integrity issue. This can be due to incorrect parameters, encoder settings, wiring faults, or external interference, leading to unreliable or lost position data.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Identify and eliminate potential interference sources (e.g., interrupted light beam, damaged reflector, faulty data cable).

2. 4

   If all checks fail, replace the SSI encoder.
