94 EM-ABS-01 for ACU 03/12
8.4 Encoder input EM-ABS-01
The encoder input is used for evaluating the position information from the encoder.
Dependin

on the encoder system used, certain parameters need to be set up. The
following table describes the use of the individual parameters for the encoder systems.

X: Parameter must be configured according to the encoder data sheet.
--- Parameter has no function for this encoder type.
(X): In the case of SSI encoders the evaluation of the division marks depends on the
setting of
Tracks/Protocol 1184.
1): Setting the offset is required in the case of synchronous motors.
In addition, the following actual value parameters are available:

8.4.1 Division marks
In parameter Division marks 1183, you can set the type-specific number of division
marks of the encoder. The number of division marks is typically described in ampli-
tudes/revolution in the case of encoders with SinCos tracks. Enter the division marks or
amplitudes/revolution in parameter
Division marks 1183.

Note:
In the case of SSI absolute value encoders, evaluation of Division marks
1183 is active only if Tracks/Protocol 1184 is described in an operation
mode for evaluation of TTL [RS-422] or SinCos tracks (settin
