10: Encoder ROQ424 (Heidenhain) SSI
11: Encoder EQI1125 (Heidenhain) EnDat
<2> Engineering note:
In the case of linear axes, the travel range must be within
the range of values of the encoder. Otherwise the range must
be shifted with the zero point offset.
In the case of EnDat multiturn encoders, P146 only applies if the
encoder pulse number (incr./rev.) corresponds to the protocol value
when multiplied by 4.
Example: EQN1325 with pulse number 2048 x 4 = protocol value 8192

The encoder connection may neither be closed nor removed when live!
The converter must be de-energized (24 V electronics power supply disconnected and DC link
fully discharged)!
NOTE:
Parameter P149.02 = 1xxx should be set if the
following general conditions exist:
1.) Use of EnDat absolute encoders
2.) Encoders with ratio of (single-turn resolution
protocol / pulse no. per revolution ) <> 4
(e. g.: EQI1325)
With this setting the protocol value is mapped in
KK0100 in its full resolution.
NOTE:
Parameter P148.07 = xxxx should be set if the
following general conditions exist:
1.) Use of SSI absolute encoders
2.) Encoders with ratio of (single-turn resolution
protocol / pulse no. per revolution) <> 4
(e. g.: ROQ424)
With this setting the protocol value and the signal
periodes (A/B track) can be processed in full
resolution.
