PT07
ZST
Home
position shift
distance Set a shift distance from the Z-phase pulse detection position in the encoder.
Up to 2
31 can be set with [Pr. PT69].
The unit will be as follows depending on the positioning mode.
In the point table method
The unit can be changed to [µm], 10 -4 [inch], or [pulse] with the setting of [Pr. PT01].
In the indexer method
It will be command unit [pulse]. (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.
Setting range: 0 to 65535
0
Refer to

PT09
DCT
Travel
distance after
proximity dog Set a travel distance after proximity dog at home position return for the count type (front
end detection, Z-phase reference) (Homing method -2, -34) and dog reference.
Up to 2
31 can be set with [Pr. PT71].
The following shows the home position return of the dog reference.
Dog type rear end reference home position return (Homing method -6, -38)
Count type front end reference home position return (Homing method -7, -39)
Dog type front end reference home position return (Homing method -10, -42)
Homing without index pulse (Homing method 19, 20, 21, 22, 23, 24, 27, 28)
The unit can be changed to 10 STM [ μ m], 10 (STM-4) [inch], or [pulse] with the setting of [Pr.
PT01].
Setting range: 0 to 65535

Rough match
output range Set a range of the command remaining distance which outputs rough match.
The unit will be as follows depending on the positioning mode.
In the point table method
The unit can be changed to 10 STM [µm], 10 (STM-4) [inch], or [pulse] with the setting of [Pr.
PT01].
In the indexer method
It will be command unit [pulse]. (A load-side rotation expressed by the number of servo
