5.2.2 Servomotor Rotation Direction
The servomotor rotation direction can be reversed with parameter Pn000.0 without changing the polarity of
the speed/position reference. This causes the rotation direction of the servomotor to change, but the polarity of
the signal, such as encoder output pulses, output from the SERVOPACK does not change. (refer to 5.3.6
Encoder Output Pulses. )
The standard setting for forward rotation is counterclockwise (CCW) as viewed from the load end of the ser-
vomotor.
Note: SigmaWin+ trace waveforms are shown in the above table.
