12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 41
12.4.12 Dog type last Z-phase reference home position return
After the front end of the proximity dog is detected, the position is shifted away from the proximity dog at the
creep speed in the reverse direction and then specified by the first Z-phase signal. The position of the first Z-
phase signal is set as the home position.
(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: -9
Address decreasing direction: -41
Dog input polarity [Pr. PT29 Function selection T-3] Refer to section 12.4.1 (2) (b) to select the dog input
polarity.
Home position return speed [Pr. PT05 Home position return speed] Set the rotation speed until a dog is detected.
Creep speed [Pr. PT06 Creep speed] Set the rotation speed after a dog is detected.
Home position shift distance [Pr. PT07 Home position shift distance], [Pr.
PT57 Home position shift distance (extension
parameter)] Set this to shift the home position, which is specified
by the Z-phase signal.
Acceleration time constant/
deceleration 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.
