P 636[0] - ENC_CH3_CycleCount = Sampling cycle in: n x 125 µs (microseconds):
ENC_CH3_CycleCount can be used to slow down the timing for the cyclical SSI
encoder evaluation. By default, ENC_CH3_CycleCount = 1, i.e. the default setting
corresponds to 125 µs sampling and cycles for the encoder evaluation. Different
settings must be viewed as special cases and must only be used when necessary.

6 Encoder
Encoder channels Ch1 to Ch3 each feature their own encoder gearing, while
encoder channel Ch4 (virtual encoders) does not feature
any encoder gearing.
In the case of encoder channel Ch2, it is assumed that the resolver will always be
used as a commutation encoder on the motor shaft. Because of this, the numerator
adjustment range is limited to a value of (+1) or (-1), while the denominator is set at a
fixed value of (+1), for the Ch2 encoder gearing ratio. This means that the only
option available is to invert the encoder signal (direction reversal).
As a whole, the encoder gearing is a scaling factor in the encoder evaluation system
and consists of numerator N (ENC_CHx_Num) for the motor side and denominator D
(ENC_CHx_Denom) for the encoder side (output side).
The following are used to configure the encoder gearing...
