3.4.8.2 Final homing point
Purpose
l Determination of the final point where the drive stops after homing.
l Avoid reversing while homing
Selection of the final homing point (C1209)
l C1209 = 0 (default setting):
Drive stops at reference point (index pulse / zero position / touch probe) or returns to that
point.
l C1209 = 1:
Drive does not stop until it has reached the real zero point. The distance covered additionally
is determined by the reference offset and the home position.
l C1209 = 61:
Drive does not stop until it has reached the target position VTPOS−NO−60 (parameter
C1301/60). The distance covered additionally is determined by the reference offset, the home
position, and the target position.
l C1209 = 71:
Drive stops at target position VTPOS−NO−70 (function block input). The distance covered
additionally is determined by the reference offset, the home position and the target position.
l C1209 = 101:
Drive stops at target position VTPOS−NO−100 (teach−in value). The distance covered
additionally is determined by the reference offset, the home position, and the target position.
Tip!
When the drive must not reverse during homing:
l Select real zero as final homing point (C1209) and
l Enter reference offset.
Like this, the braking distance after homing is always long enough.
