8.4.1 Servomotor Rotation Direction
The servomotor rotation direction can be reversed with parameter Pn000.0 without changing the polarity of
the speed/position reference. The standard setting for forward rotation is counterclockwise (CCW) as viewed
from the load end of the servomotor.
Note: SigmaWin for Σ-V-SD (MT) trace waveforms are shown in the above table.
