7050: Incremental encoder: Illegal AB signal change

Info: Encoder
Data type: USINT

Description:
Runtime error in an incremental/SinCos encoder with activated monitor (activation, see error number 7030).
Illegal change of the quadrature signal (AB incremental encoder signals / SinCos encoder signals).
For encoders with SinCos similar signals, the quadrature signal corresponds to the quadrants of the unit circle.

Reaction:
See error number 7030.

Cause/Remedy:
Encoder speed too high.
Encoder connection is interrupted or defective. See wiring guidelines error number 7030.
The phase shift between signal A and B is not equal to 90 degrees
Encoder vibrations.
Encoder/Module defective.
