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

CC

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

voltage drop [DV] on the encoder cable:

 Stop!

Observe the permissible supply voltage of the encoder used. If the

values in C0421 are set too high, the encoder can be destroyed!
