[Pr. PT01]
0
Absolute value command method
2) Rotation direction selection ([Pr. PA14])
Select the servo motor rotation direction when "Controlword bit 4 (New set-point)" is switched on.
[Pr. PA14] setting
Servo motor rotation direction
"Controlword bit 4 (New set-point)" on
0
CCW rotation with + position data
CW rotation with - position data
1
CW rotation with + position data
CCW rotation with - position data
CW
CCW
3) Position data unit ([Pr. PT01])
Set the unit of the position data.
[Pr. PT01] setting Position data unit
_ 0 _ _ mm
_ 1 _ _ inch
_ 3 _ _ pulse
4) Feed length multiplication ([Pr. PT03])
Set the feed length multiplication factor (STM) of the position data.
[Pr. PT03] setting
Position data input range (Note 1)
[mm] [inch] [pulse] (Note 2)
_ _ _ 0 - 999.999 to + 999.999 - 99.9999 to + 99.9999
_ _ _ 1 - 9999.99 to + 9999.99 - 999.999 to + 999.999
- 999999 to + 999999
_ _ _ 2 - 99999.9 to + 99999.9 - 9999.99 to + 9999.99
_ _ _ 3 - 999999 to + 999999 - 99999.9 to + 99999.9
Note 1. The "-" sign has different meanings under the absolute value command method and the incremental value
command method. Refer to section 7.2.1 for details.
2. The feed length multiplication setting ([Pr. PT03]) is not applied to the unit multiplication factor.
Adjust the unit multiplication factor in the electronic gear setting ([Pr. PA06] and [Pr. PA07]).
