Homing methods

EEh -18 Positive stop
1)2)3)
1. Travel at search speed in positive direction to
the stop. This position is taken as the homing
point.
2. If this is parameterised: travel at positioning
speed to the axis zero point.
E9h -23 Reference switch in positive direction with travel
to stop or limit switch.
1. Run at search speed in positive direction to
stop or limit switch .
2. Travel at search speed in negative direction to
the reference switch.
3. Travel at creep speed in negative direction un-
til the homing switch becomes inactive. This
position is taken as the homing point.
4. If the axis zero point ≠ 0: Travel at positioning
speed to the axis zero point.
Homing Switch
E5h -27
Reference switch in negative direction with
travel to stop or limit switch
1. Run at search speed in negative direction to
stop
or limit switch
.
2. Travel at search speed in positive direction to
the reference switch.
3. Run at crawl speed in positive direction until
reference switch becomes active. This posi-
tion is taken as the homing point.
4. If this is parameterised: travel at positioning
speed to the axis zero point.
Homing 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.
