10 Malfunctions
For any work performed on the motor during which the sealed connections of the
safety-rated encoder are loosened, you must observe the notes in chapter "Functional
Safety" (→
2 23).
10.1 Encoder malfunctions
When a BY.. brake is used, the working air gap of the brake must be measured at reg-
ular intervals, which are specified in the "CMP40 – 112, CMPZ71 – 100 Synchronous
Servomotors" operating instructions in chapter "Inspection/Maintenance".
A working air gap that exceeds the permitted maximum value can cause encoder er-
rors or destroy the encoder.
Encoder malfunctions are displayed at the inverter with a corresponding error mes-
sage, or at the higher-level encoder evaluation unit.
