EDSVS9332P−EXT DE 2.0
3.4.8.4 Homing modes 0 and 1
Purpose
l Simple homing in all positioning modes (C1210 = 0, 1, 2).
l The homing switch (POS−REF−MARK) must be in direction of the movement.
Move to reference point via homing switch
Mode 0: Traversing direction to positive end of travel range limit switch
Set C1213 = 0.

Fig. 3−16 Move to reference point via homing switch
Function sequence
l Move to the reference point with homing speed (C1242) towards positive end of travel range
limit switch overtravelling the homing switch.
l The reference point is at the first zero pulse / zero position of the position encoder after leaving
the homing switch.
The drive can be on the homing switch before homing.
Mode 1: Traversing direction to negative end of travel range limit switch
Set C1213 = 1.
Function sequence
l Like mode 0, but the drive traverses in negative direction to travel range limit switch.
