Multiturn encoder evaluation for motor encoder (SBM2 in slot C)
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)!

In the case of EnDat multiturn encoders, P146 only applies if the
RS 422 standard
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

following general conditions exist:
1.) Use of EnDat absolute encoders
2.) Encoders with ratio of (single-turn resolution
F051 Encoder fault
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.
