Option 1: Homing to a Home Switch

Legend
A = Stop Position/Marker Pulse
B = Acceptance of New Position (Norming of the Absolute Position)
V1 = Parameter - Homing Velocity
V2 = 25% of the Parameter - Homing Velocity
V3 = max. 10 increments/controller cycle (system velocity)
V4 = max. 1 increment/controller cycle (system velocity)
X = > 1/16 and < 15/16 Feed Constant
1.): If the carriage is not positioned on the home switch cam, it is
moved to the home switch cam using the homing velocity
designated in Parameter Ax24.
2.): As soon as the cam switch is activated, the carriage reverses and
moves off the cam using 1/4 of the Parameter Homing Velocity.
After leaving the cam, the carriage is reversed again and moved
to the cam at 10 increments per controller cycle (see Parameter
B010), until the first marker pulse from the incremental encoder
has been evaluated. Now the carriage is reversed again, and
moved to the exact position of the marker pulse (± 1 increment) at
1 increment per controller cycle.
