EDKCSDX064 DE/EN/FR 3.0
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 [

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