17h 23 Reference switch in positive direction
1. If reference switch inactive:
Travel at search speed in positive direction to
the reference switch.
If the stop or limit switch is approached:
Travel at search speed in positive direction to
the reference switch.
2. Travel at creep speed in negative direction un-
til the homing 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.
Homing Switch
1Bh 27 Reference switch in negative direction
1. If reference switch inactive:
Travel at search speed in negative direction to
the reference switch.
If the stop or limit switch is approached:
Travel at search speed in positive direction to
the reference switch.
2. Travel at creep speed in positive direction until
the homing switch becomes inactive. This pos-
ition is taken as the homing point.
3. If this is parameterised: travel at positioning
speed to the axis zero point.
Homing Switch
21h 33 Index pulse in negative direction
1)
1. Travel at creep speed in negative direction un-
til the index pulse. This position is taken as
the homing point.
2. If this is parameterised: travel at positioning
speed to the axis zero point.
Index pulse
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.
