Indexed Actual Value Acquisition - Siemens Sinamics S120 Function Manual

Function modules
7.7 Closed-loop position control
Using the connector input p2515 (position setting value) and a "1" signal at binector input
p2514 (set position actual value), a position setting value can be entered.
When the actual position value is set (p2514 = "1" signal), the actual position value of the
position controller is kept at the value of connector p2515 as standard.
Incoming encoder increments are not evaluated. A difference in position cannot be
compensated for in this situation.
An inversion of the actual position value resulting from the encoder is undertaken using
parameter p0410. An inversion of the axis motion can be entered using a negative value in
p2505.
