5.4 Motor Direction Setting

5.4 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.
This causes the rotation direction of the Servomotor to change, but the polarity of the signals,
such as encoder output pulses, output from the SERVOPACK do not change. Set the appropri-
ate direction for your system.
Refer to the following section for details on the encoder divided pulse output.
6.5 Encoder Divided Pulse Output on page 6-9
• Rotary Servomotors
The default setting for forward rotation is counterclockwise (CCW) as viewed from the load end of the Servomotor.
However, for overtravel, the rotation direction is the direction as viewed from the encoder.
Note: The trace waveforms of the SigmaWin+ are shown in the above table for the torque reference and motor speed diagrams. If you
measure them on a measuring instrument, e.g., with an analog monitor, the polarity will be reversed.
• 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 SigmaWin+ are shown in the above table for the force reference and motor speed diagrams. If you mea-
sure them on a measuring instrument, e.g., with an analog monitor, the polarity will be reversed.
