No. Meaning
Default
P01
Type of movement (free run, relative / absolute,
reference run)
0 = Rotational movement (ignoring limit switches)
1 = Hardware limit switches are monitored
for XY tables or other linear systems,
2 limit switches:
Mechanical zero and limit direction –
Limit dir
2 = Software limit switches are monitored
3 = Hardware and software limit switches are monitored
0
P02
Measuring units of movement: only used for displaying
1 = step
2 = mm
3 = inch
4 = degree
1
P03
Conversion factor for the thread
1 step corresponds to ...
If P03 = 1 (steps) the conversion factor is 1.

P04
Start/stop frequency
The start/stop frequency is the maximum frequency to
start or stop the motor without ramp. At higher frequen-
cies, step losses or motor stop would be the result of a
start or stop without ramp. The start/stop frequency
depends on various factors: type of motor, load,
mechanical system, power stage.
The frequency is programmed in Hz.
