hex dec Descript ion
01h 1 Negative limit switch with index pulse
1)
1. If negative limit switch inactive:
Run at search speed in negative direction to
the negative limit switch.
2. Travel at creep speed in a positive direc tion
until the limit 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
Negative limit switch
02h 2 Positive limit switch with index pulse
1)
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 direc tion
until the limit 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
Positive limit switch
07h 7 Reference switch in positive direction with index
pulse
1)
1. If reference switch inactive:
Travel at search speed in positive 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 negative direc tion
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
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.
