5.5 Motor Direction Setting
5-16
5.5
Motor Direction Setting
You can reverse the direction of Servomotor rotation by changing the setting of Pn000 =
n.
X (Direction Selection) without changing the polarity of the speed or position reference.
•
Rotary Servomotors
The default setting for forward rotation is counterclockwise (CCW) as viewed from the load end
of the Servomotor.
Note: The trace waveforms of the S are shown in the above table for the torque reference and motor
speed diagrams.
•
Linear Servomotors
Before you set this parameter, make sure that Pn080 = n.
X
(Motor Phase Sequence
Selection) is set correctly.
Note: The trace waveforms of the S are shown in the above table for the force reference and motor speed
diagrams.
