Illustration 10: Encoder Signals in Closed-loop Control
When an absolute encoder is used, the cables for the absolute data are connected directly to the encoder board id slot C. The Sin-
Cos/Digital pulse signal cables are connected to the Advanced safety option board and from there to the option board in slot C.
Illustration 11: Absolute Encoder Signals in Closed-loop Control
This configuration enables the use of absolute encoder with position data for control. The safety functions are implemented with-
out the absolute data, and the safety functions with position monitoring are monitoring the relative position based on the incre-
mental signals from the encoder.
