0B 11 Reference switch in negative direction with index
pulse
1)
1. If reference switch inactive:
Travel at search speed in negative direction to
the reference switc h.
If the stop or limit switch is approached:
Travel at search speed in positive direction to
the reference switc h.
2. Travel at creep speed in positive direction until
the homing switch becomes inactive, then
continue to the first index pulse. This position
is taken as the homing point.
3. If this is parameterised: travel at positioning
speed to the axis zero point.
Index pulse
Homing Switch
11h 17 Negative limit switch
1. If negative limit switch inactive:
Run at search speed in negative direction to
the negative limit switch.
2. Travel at creep speed 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
speed to the axis zero point.
Negative limit switch
12h 18 Positive limit switch
1. If positive limit switch inactive:
Run at sea r ch speed in positive direction to
the positive limit switch.
2. Travel at creep speed 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
speed 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
mustbe≠0.
