6.6.11 Changing the Switch-Off Difference (JOB 3)
Definition
Changing the switch-off difference allows you to adjust the drive control to adapt to any
changes in the load and mechanical conditions.
Supply the control interface with the new switch-off difference, and activate JOB 3.
The 1PosSSI/Analog accepts the preset switch-off difference.
The switch-off difference remains valid until the parameter assignment of the PosSSI/Analog
is changed.
Effect on the MODEs
MODE What Happens
Inching -
Absolute Positioning
Relative Positioning
Distance to the destination ≤ switch-off difference
The switch-off point is reached or overshot; positioning is
switched off immediately, and the run is terminated with
POS_DONE = 1. In this case, the destination is sometimes
overshot.
