Feedback error compensation
Feedbacks with sine/cosine tracks may have different errors. The feedback error
compensation supported by Compax3 eliminates offset and gain errors on both
tracks online.
The feedback error compensation is activated in the MotorManager:
"Feedback system" wizard under "feedback error compensation".

In order to accept the changes in the MotorManager in the project, the individual
configuration pages must be clicked through. In order to make the changes made
in the MotorManager effective in the device, the configuration download in the
C3Manager must be executed.
In the event of formal errors, the feedback error compensation may however be
disadvantageous; therefore it is switched off as a default.
