[Pr. PT08_Homing position data (ZPS)]

Initial value
0 [Refer to the text below for the unit.]
Set the address that is to be the reference point of the machine coordinate system.
Subtracting the setting value of this servo parameter from the machine home position gives the coordinate of the home
position. The value in [Position actual value (Obj. 6064h)] changes at the same time as the homing completion.
The setting value of this servo parameter is reflected at completion of homing or when the servo amplifier is connected to a
network.
This function is enabled in the cyclic synchronous position mode, profile position mode, and positioning mode (point table
method).
The unit is the command unit. The unit can be changed to 0.001 mm, 0.0001 inch, 0.001 degree or pulses with [Pr. PT01.2
Unit for position data].
If [Pr. PT01.2] is changed, the homing position data will also be changed. Execute homing again.
This function corresponds to [Home offset (Obj. 607Ch)]. The relation between [Home offset] and this servo parameter is as
follows.
[Home offset] = - [Pr. PT08]
The value that is set in this servo parameter is not reflected when the homing is incomplete.
Setting this servo parameter will compensate the software position limit.
After compensation, [Max position range limit (607Dh: 02h)] = [Max position range limit] - [Home offset]
After compensation, [Min position range limit (607Dh: 01h)] = [Min position range limit] - [Home offset]
Min position

The setting range is 0 to 359.999 degrees for the degree unit. If a value out of the setting range is set, the value will be
converted as shown in the table below.
