Via the 9−pole Sub−D−plug X8, you can connect the following encoders:
ƒ Incremental encoder (TTL encoder)
– with two 5 V complementary signals (RS−422) that are electrically
shifted by 90°.
– with zero track that can be connected optionally.
ƒ Sin/cos encoder (singleturn or multiturn rotary transducer)
– with supply voltage (5 ... 8 V).
– with serial communication.
The initialisation time of the axis module is extended to approx. 2 s.
The controller supplies the encoder with voltage.
Use C0421 to set the supply voltage V

(5 ... 8 V) to compensate, if required, the
voltage drop [

Stop!
Observe the permissible supply voltage of the encoder used. If the
values in C0421 are set too high, the encoder can be destroyed!
