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 Device/parameter to be used Setting
Homing mode selection MD0 (Operation mode selection 1) Switch on MD0.
DI0 (Point table No. selection 1) to DI7 (Point
table No. selection 8) Switch off DI0 to DI7.
Home position return
direction [Pr. PT45 Home position return types] Select the homing direction with [Pr. PT45]. The
setting is shown as follows:
Address increasing direction: -4
Address decreasing direction: -36
Home position return speed [Pr. PT05 Home position return speed] Set the rotation speed until the workpiece is pressed
against the mechanical stopper.
Stopper time [Pr. PT10 Stopper type home position return -
Stopper time] 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.
Stopper type home position
return - Torque limit value [Pr. PT11 Stopper type home position return -
Torque limit value] Set the servo motor torque limit value when executing
the stopper type homing.
Acceleration time constant of
homing [Pr. PT61 Home position return acceleration
time constant] or [Pr. PT62 Home position
return deceleration time constant] 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.
Homing position data [Pr. PT08 Home position return position data],
[Pr. PT58 Home position return position data
(extension parameter)] Set the current position at the time of homing
completion.
