Adjustment
ƒ Homing speed
– First the drive searches for the limit switch using the search speed. For
determining the position of the switching edge exactly, the drive changes to the
creep speed. Both speeds are set in SDC.
ƒ Acceleration
– The acceleration is set in SDC.
ƒ Homing mode
– A description of the different homing methods is given in the software manual of
the controller.
ƒ Shifting of the zero position
– Via PNU 1051.0 the zero position of the drive can be shifted. The value under
PNU 1051.0 is added to the value of the homing point (e.g. limit switch position).
)
Note!
Traversing to the zero position is not part of the homing run. If the controller
knows all parameters required (e.g. the position of the zero pulse), no physical
movement is executed.
