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.
Before you set this parameter, make sure that Pn080 = n.X (Motor Phase
Sequence Selection) is set correctly.

6.6 Setting the Linear Encoder Pitch
If you connect a linear encoder to the SERVOPACK through a Serial Converter Unit, you
must set the scale pitch of the linear encoder in Pn282.
If a Serial Converter Unit is not connected, you do not need to set Pn282.
