Good day Excuse me, I have a cobot milling M5 models but I have two very rare alarms, the first observation is new and the alarm was being tested in the software "Shaft driver failure, driver failure code: 45" but it stayed in stop mode, the robot no longer moves, Not in automatic mode either. my code 45 says "magnetic coding module failure-optical coding failure"" 1. Check whether the optical encoder disc is contaminated or not stuck firmly. 2. If the fault is still not cleared, please repair or replace the assembly of magnetic brais" As I told you, it is new, it is rare that the encoder does not work or is damaged.
