Fig. 3−18 Move to POS−REF−MARK, reverse and move to reference point
Function sequence
l Move towards travel range limit switch with homing speed C1242 up to homing switch
(case ).
l Reverse there and move to the reference point. The homing switch must be assigned during
the entire homing process!
l The reference point is at the first zero pulse / zero position of the position encoder after leaving
the homing switch.
l If the drive is already positioned on the homing switch before homing it is reversed
immediately (case ).
Mode 5: Traversing direction to negative end of travel range limit switch
Set C1213 = 5.
Function sequence
l Like mode 4, but the drive traverses in negative direction of travel range limit switch.
