12.4.17 Automatic positioning to home position function
POINT
The automatic positioning to the home position cannot be performed from
outside the setting range of position data. In this case, perform the homing again
using the homing.
When returning to the home position again with the home position fixed after power-on, this function enables
a high-speed automatic positioning to the home position.
If the automatic positioning to the home position is executed without completing the homing, [AL. 90.1 Home
position return incomplete warning] occurs.
After the power-on, perform the homing in advance.
(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 speed [Pr. PT05 Home position return speed] Set the servo motor speed to move to the home
position.
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.
