6.1.1.1 Distance / Longitudes Parameters
Slow forward/slow backward = middle speed
This parameter serves the input of the distance, at which the controller switches from high speed to
slow speed before reaching the target position.
Creep forward/creep backward = slow speed
This parameter serves the input of the distance, at which the controller switches from slow speed to
creep speed before reaching the target position.
Correction stop forward/correction stop backward
Here a constant overrun can be compensated.
Example:
The target position is overrun by 0.2 mm constantly. The data entry has to be 0.2mm.
The stop command is then moved forward by 0.2 mm.
When starting the operation the stop offset is set first to "0" in order to be able to calibrate the
overrun accurately. For an exact positioning the stop offset should be as small as possible (0.0 to
0.2 mm) i.e. the mechanical friction should be steady over the entire run distance and the slow
speed and/or creep speed must be adjusted accordingly small.
INFORMATION!
When positioning with PID, the correction stop
serves as tolerance window.
