0B 11 Reference switch in negative direction with index
pulse
1)
1. If reference switch inactive: Travel at search
velocity in negative direction to the reference
switch.
If the stop or limit switch is approached:
Travel at search velocity in positive direction
to the reference switch.
2. Travel at crawling velocity in positive direction
until the reference switch becomes inactive,
then continue to the first index pulse. This po­
sition is taken as the homing point.
3. If this is parameterised: travel at positioning
velocity to the axis zero point.

Negative limit switch
1. If negative limit switch inactive:
Run at search velocity in negative direction to
the negative limit switch.
2. Travel at crawling velocity in positive direction
until the limit switch becomes inactive. This
position is taken as the homing point.
3. If this is parameterised: travel at positioning
velocity to the axis zero point.
Negative limit switch
12h 18 Positive limit switch
1. If positive limit switch inactive:
Run at search velocity in positive direction to
the positive limit switch.
2. Travel at crawling velocity in negative direction
until the limit switch becomes inactive. This
position is taken as the homing point.
3. If this is parameterised: travel at positioning
velocity to the axis zero point.
Positive limit switch
1) Only possible for motors with encoder/resolver with index pulse.
2) Limit switches are ignored during travel to the stop.
3) Since the axis is not to remain at the stop, the travel to the axis zero point must be parameterised and the axis zero point offset
must be ≠ 0.
