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.
