Operating Instructions, 04/2014, FW V4.7, A5E34261542B AA
The converter can evaluate up to two encoders (see also Section:
Encoder assignment (Page 60)):
1. An HTL encoder on the motor shaft.
The HTL encoder can be used for position sensing as well as for
speed measurement for the speed controller.
2. An encoder with an SSI interface on the load side.
You can use the SSI encoder only for position sensing.
If you use an HTL encoder, either select one of the standard encoders
or enter the encoder data, also see section: Adapting the encoder data
(Page 75).
...R: Encoder with zero mark
If you use an SSI encoder, either select one of the standard encoders or
enter the encoder data, also see section: Adapting the encoder data
(Page 75).
