Sin/ cos encoder
Features of the sin/cos encoder:
z The following encoders can be connected
– Sin/cos encoders with a rated voltage from 5 V to 8 V.
– Sin/cos encoders with a communication interface of type Stegmann SCS/M70xxx
(the initialisation time of the controller is increased to approx. 2 seconds).
