[28] Default movement direction for excitation-phase signal detection
(Parameter No.34)
No. Name Symbol Unit Input Range
Default factory

34 Default movement direction for
excitation-phase signal detection
PHSP –
0: Reverse
1: Forward
In accordance
with actuator
Excitation detection
(Note)
starts when the servo is turned ON for the first time after the power is
supplied. Detection direction at this time is determined.
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.17 Home Return Direction. If the direction in opposite, set the
other values from Parameter No.17. (If No.17 is 0, set 1. If No.17 is 1, set 0.)
(Note) In Simple Absolute Type, the excitation phase signal detection is executed at the
home-return operation complete.
[29] Exicitation-phase signal detection time (Parameter No.35)
No. Name Symbol Unit Input Range

35 Exicitation-phase signal detection

In accordance
with actuator
Excitation detection
(Note)
starts when the servo is turned ON for the first time after the power is
supplied. Detection direction at this time is determined.
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) In Simple Absolute Type, the excitation phase signal detection is executed at the
home-return operation complete.

Excitation detection
(Note)
is executed at the first servo-on after the power is supplied, and in the
new method, we succeeded to make this operation smoother and 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.
