0
Set when using a motor for which
forward rotation (encoder) is clockwise
(CW) viewed from the shaft.
Set for the operation at
120 Hz or less.
100
Set for the operation at a
frequency higher than
120 Hz.
1
Set when using a motor for which
forward rotation (encoder) is
counterclockwise (CCW) viewed from
the shaft.
Set for the operation at
120 Hz or less.
101
Set for the operation at a
frequency higher than
120 Hz.
