Machine
parameter Function and input Change
via Reaction Page
MP1350.0–4 Type of reference mark approach
Entry values: 0 or 1
+0 = Encoder with distance–coded
reference marks (for square-wave inputs
the encoder must have a 5-fold EXE if
distance-coded reference marks are used.)
+1 = Encoder without distance–coded reference
marks
4–34

MP1530 Overshoot behavior during acceleration with
feedforward.
It influences the overshoot behavior during
acceleration in the gap control in feedforward
mode.
Entry range: 0 to 0.999
If MP1530 is programmed to equal 0, the
standard value 0.25 is used.
Input value 0.999 = steepest characteristic curve -
MP1540 Braking behavior during feedforward
It influences braking to a target in feedforward
mode.
Entry range: 0 to 0.999
If MP1530 is programmed to equal 0, the
standard value 0.5 is used.
Input value 0.999 = steepest characteristic curve -
MP1550 Filter for feedforward
Entry range: 0 or 1
1 = Switch off the filter in the feedforward
voltages -
MP1700 Selecting the system cycle times
Entry: 0 to 2
