6.4.2 Torque limit changing dog type home position return
This is a home position return method using an external limit. Deceleration starts at the external limit
detection. The position specified by the first Z-phase signal, or the position of the first Z-phase signal shifted
by the specified home position shift distance is used as the home position.
(1) Device/parameter
Set input devices and parameters as follows.
Item Used
device/parameter
Setting
Home position return mode
selection
MD0 (Operation mode selection 1)
Switch off MD0.
MD1 (Operation mode selection 2)
Switch off MD1.
Torque limit changing dog
type home position return
[Pr. PT04]
Select "_ _ _ 0" (Torque limit changing dog type).
Home position return speed
[Pr. PT05]
Set the rotation speed specified until an external
limit is detected.
Creep speed
[Pr. PT06]
Set the rotation speed specified after an external
limit is detected.
Home position shift distance
[Pr. PT07]
Set this item to shift the home position, which is
specified by the first Z-phase signal after the
external limit is detected.
Acceleration time
constant/Deceleration time
constant
RT (Second acceleration/deceleration
selection)
1. When RT is turned off
Acceleration time constant: setting value of [Pr.
PC01 Acceleration time constant 1]
Deceleration time constant: setting value of [Pr.
PC02 Deceleration time constant 1]
2. When RT is turned on
Acceleration time constant: setting value of [Pr.
PC30 Acceleration time constant 2]
Deceleration time constant: setting value of [Pr.
PC31 Deceleration time constant 2]
Station home position shift
distance (Note 1, 2)
[Pr. PT40]
Set a shift distance of the station home position
(station No. 0) for the home position return
completion.
Note 1. The setting of the station home position shift distance is disabled at home position return. Cycling the power will
enable the setting.
2. [Pr. PT40 Station home position shift distance] is enabled as an offset to the position that the home position return
is performed. If a larger value than the in-position range is set to [Pr. PT40], the completion output of positioning will
not turn on (short circuit) at the first power on after home position return.
