DRIVE- -CLiQ encoder
If a DRIVE--CLiQ encoder is connected for the NCK monitoring channel (drive
parameter r9527 = 2 or 3), in addition to the parameter field r0979, additional drive
parameters that define the redundant coarse position value in more detail must be
read--out. When booting, these parameters are directly read--out of the encoder
and saved in the NCK machine data.
The additional parameters for DRIVE--CLiQ encoders are listed in the following
