KK104 is supported only when used with an
external encoder with incremental tracks
(sine/cosine tracks) (P135 = 4).

<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 shifter with the zero value 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

When using position detection via
external encoder (FP335), the
following setting is required:
U950.18
U950.17
SBM (6SE7090-0XX84-0FD0)
2 hook switches for voltage supply of the
encoder on the board:
5 V : Both switches open
7.5 V : S1 open, S2 closed
15 V : Both switches closed

Setting of the supply voltage in volts via P145
(Maximum value of the output voltage:
in the case of Compact units: 15 V
in the case of Compact PLUS units: 19 V
independent of parameterizing)
It is not possible to evaluate the motor temperature for
encoder evaluations that are not inserted in slot C.
WARNING
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 P149.08 = 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 P148.08 = 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.
