When the ECSxA... axis module is switched on, this monitoring function repeatedly
downloads the absolute value of the hiperface absolute value encoder to identify whether
the same value is transferred to the drive.
The absolute value encoders (single−turn, multi−turn) are supported by a hiperface
interface with various numbers of increments, e.g.: SRM50 with 1024 Sin/Cos periods/rev.
or SKM38 with 128 periods/rev.(see also C0419).
If a deviation > 5° on the motor shaft is detected, the monitoring (TRIP) is actuated.
The fault message "Sd7" can only be reset by mains switching!
