Operation
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 signals, such as encoder output pulses, output from the multi-winding drive unit 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.
