[Pr. Pt05_Homing Speed (Zrf)]; [Pr. Pt06_Creep Speed (Crf)]; [Pr. Pt07_Home Position Shift Distance (Zst)]; [Pr. Pt08_Homing Position Data (Zps)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G User Manual

[Pr. PT05_Homing speed (ZRF)]

Initial value
100.00 [r/min], [mm/s]
Set the servo motor speed for homing.
The servo motor speed is clamped at the maximum speed. When changing the speed to the permissible speed, set the speed
in [Pr. PA28.4 Speed range limit selection].
If the set speed exceeds 8000 r/min (mm/s), the speed is clamped at 8000 r/min (mm/s). However, the set speed is clamped
when [Pr. PT02.7 Internal position command - Process speed selection] is set to "0".
This function corresponds to [Speed during search for zero (Obj. 6099h: 2h)].
When the object is mapped to the cyclic communication, do not write values with engineering tools because the controller
overwrites the servo parameter values written with engineering tools.
This function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "0". This function and [Pr.
PV11 Homing speed extension setting] are mutually exclusive.

[Pr. PT06_Creep speed (CRF)]

Initial value
10.00 [r/min], [mm/s]
When performing a homing, set the servo motor speed after proximity dog.
The servo motor speed is clamped at the maximum speed. When changing the speed to the permissible speed, set the speed
in [Pr. PA28.4 Speed range limit selection].
If the set speed exceeds 8000 r/min (mm/s), the speed is clamped at 8000 r/min (mm/s). However, the set speed is clamped
when [Pr. PT02.7 Internal position command - Process speed selection] is set to "0".
This function corresponds to [Speed during search for switch (Obj. 6099h: 1h)].
When the object is mapped to the cyclic communication, do not write values with engineering tools because the controller
overwrites the servo parameter values written with engineering tools.
This function is enabled when [Pr. PT01.1] is set to "0". This function and [Pr. PV13 Creep speed extension setting] are
mutually exclusive.

[Pr. PT07_Home position shift distance (ZST)]

Initial value
0 [pulse]
Set the home position shift travel distance at homing.

[Pr. PT08_Homing position data (ZPS)]

Initial value
0 [pulse]
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 and the profile position mode.
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]
