For linear encoders, the interrelationship between the physical quantity and the neutral
length unit LU is configured using parameter p2503 (LU/10 mm).
Example:
Linear encoder, 10 mm should have a resolution of 1 µm (i.e. 1 LU = 1 µm).
→ p2503 = 10000

A correction can be made using connector input p2513 (correction value, position actual
value conditioning) and a positive edge at binector input p2512 (activates the correction
value). When the "basic positioning" function module is activated, p2513 is automatically
interconnected with r2685 (EPOS correction value) and p2512 with r2684.7 (activate
correction). This interconnection enables modulo offset by EPOS, for example.
p2516 can be used to switch in position offset. Using EPOS, p2516 is automatically
interconnected to r2667. Backlash compensation is implemented using this interconnection.
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.
