12.4.7 Stopper type homing

For the stopper type home position return, the home position is set where the workpiece is pressed against
the stopper of the machine by using the JOG operation, the manual pulse generator operation, or others.
(1) Device/parameter
Set input devices and parameters as follows:
Item
Homing mode selection
Home position return
direction
Home position return speed
Stopper time
Stopper type home position
return - Torque limit value
Acceleration time constant of
homing
Homing position data
Device/parameter to be used
MD0 (Operation mode selection 1)
DI0 (Point table No. selection 1) to DI7 (Point
table No. selection 8)
[Pr. PT45 Home position return types]
[Pr. PT05 Home position return speed]
[Pr. PT10 Stopper type home position return -
Stopper time]
[Pr. PT11 Stopper type home position return -
Torque limit value]
[Pr. PT61 Home position return acceleration
time constant] or [Pr. PT62 Home position
return deceleration time constant]
[Pr. PT08 Home position return position data],
[Pr. PT58 Home position return position data
(extension parameter)]
Switch on MD0.
Switch off DI0 to DI7.
Select the homing direction with [Pr. PT45]. The
setting is shown as follows:
Address increasing direction: -4
Address decreasing direction: -36
Set the rotation speed until the workpiece is pressed
against the mechanical stopper.
Set the time from when the home position data is
obtained after the machine presses against its stopper
until when ZP (home position return completion) is
outputted.
Set the servo motor torque limit value when executing
the stopper type homing.
The acceleration/deceleration time constant of [Pr.
PT61] or [Pr. PT62] is used.
Set [Pr. PT60 Function selection T-8] to select the
parameters to be used.
Set the current position at the time of homing
completion.
