PT57
ZSTH
Home position
shift distance
(extension
parameter) This parameter is the extension parameter of [Pr. PT07].
When [Pr. PT57] is used, the home position shift distance is calculated
as follows.
Home position shift distance = [Pr. PT07] + ([Pr. PT57] × 65536)
The unit will be as follows depending on the positioning mode.
For point table method
It will be change to [μm], 10 -4 [inch], or [pulse] with the setting of [Pr.
PT01].
Indexer method
It will be command unit [pulse]. (unit of a load-side rotation expressed
by the number of servo motor resolution pulses)
Refer to the Function column of [Pr. PA10] for the command unit.
Additionally, when a value equal to or more than "1001" is set, the value
will be clamped to "1000".
Setting range: 0 to 32767

PT58
ZPSH
Home position
return position
data
(Extended
parameters) This parameter is the extension parameter of [Pr. PT08].
When [Pr. PT58] is used, the home position shift distance is calculated
as follows.
Home position return position data = [Pr. PT08] + ([Pr. PT58] x 65536)
The unit is changed to 10
STM [μm], 10 (STM-4) [inch], or [pulse] with the
setting of [Pr. PT01].
Additionally, when the following parameters are changed, the home
position return position data is changed. Execute the home position return
again.
"Position data unit" in [Pr. PT01]
"Feed length multiplication (STM)" in [Pr. PT03]
"Home position return type" in [Pr. PT45]

DCTH
Travel
distance after
proximity dog
(extension
parameter) This parameter is the extension parameter of [Pr. PT09].
When [Pr. PT59] is used, the travel distance after proximity dog is
calculated as follows.
Travel distance after proximity dog = [Pr. PT09] + ([Pr. PT59] × 65536)
The unit is changed to 10
STM [μm], 10 (STM-4) [inch], or [pulse] with the
setting of [Pr. PT01].
Setting range: 0 to 32767

Function
selection T-8 _ _ _ x Home position return - Deceleration time constant selection
Select a parameter used for setting the deceleration time constant at
home position return.
The acceleration time constant is fixed to [Pr. PT61].
0: Using [Pr. PT61] as deceleration time constant.
1: Using [Pr. PT62] as deceleration time constant.
