Incremental encoder connection
Terminal strip X17 has a double function. When supplied, the terminals
are used as digital inputs. A connection for an HTL incremental encoder
can be selected using parameter P0130 (encoder selection).
Note to Engineering/configuring instructions
The maximum cable length between the encoder and evalua-
tion electronics depends on the encoder
Observe the limiting frequency of the evaluation electronics as
well as the encoder.
