[21] Default movement direction for excitation-phase signal detection (Parameter No.28)
No. Name Symbol Unit Input Range
Default factory
setting
28 Default movement direction for
excitation-phase signal detection
PHSP –
0 : Reversed
direction
1 : Forward
direction
In accordance
with actuator
Excitation detection (Note) starts when the servo is turned ON for the first time after the power is
supplied. Define the detection direction at this time.
Even though it is generally unnecessary to change this setting, set this to the direction which
the motor is easy to move when the actuator interferes with the mechanical end or peripheral
object at the time the power is supplied.
If the direction not interfering is the same direction as the home return direction, set the same
values as set to Parameter No.5 Home Return Direction. If the direction is opposite, set the
other values from Parameter No.5. (If No.5 is 0, set 1. If No.5 is 1, set 0.)
(Note) For Simple Absolute Type, the excitation detection is performed at the end of home
return operation.
[22] Excitation-phase signal detection time (Parameter No.29)
No. Name Symbol Unit Input Range
Default factory
setting
29 Excitation-phase signal detection
time
PHSP msec 1 to 999
In accordance
with actuator
Excitation detection (Note) starts when the servo is turned ON for the first time after the power is
supplied. Define the detection direction at this time.
Even though it is generally unnecessary to change this setting, changing the setting of this
parameter may be effective when excitation error is generated or abnormal operation is
confirmed.
Please contact us in the case a change is necessary to this parameter.
(Note) For Simple Absolute Type, the excitation detection is performed at the end of home
return operation.
[23] Excitation detection type (Parameter No.30)
No. Name Symbol Unit Input Range
Default factory
setting
30 Excitation detection type PHSP –
0 : Conventional
method
1 : New method 1
(For vertical
mount
installation)
2 : New method 2
(For horizontal
mount
installation)
In accordance
with actuator
Excitation detection (Note) starts when the servo is turned ON for the first time after the power is
supplied. In the new method, this operation was made smoother, thus quieter than ever (if
compared with our existing products).
In the case the new method 2 (horizontal mount installation) is set and the actuator is mounted
vertically, the slider or the rod may drop at the excitation operation. Follow the instructed
orientation to install. If the slide or rod drops with the mentioned way of installation, set with the
current setting.
(Note) For Simple Absolute Type, the excitation detection is performed at the end of home
return operation.
