5. OPERATION
2) ST1 coordinate system selection (parameter No.1)
Choose the servo motor rotation direction at the time when the forward rotation start (RYn1)
signal or reverse rotation start (RYn2) signal is switched on.
Parameter No.1 setting
RYn1:ON
CCW
3) Feed length multiplication selection (parameter No.1) Set the unit multiplication factor (STM) of
position data. The actual moving distance is the result of multiplying the entered position data
by the unit multiplication factor.
Parameter No.1 setting Feed length multiplication STM [Times]

(c) Operation
Choosing the point table using RYnA to RYnE and turning RYn1 ON starts a motion in the
forward rotation direction over the moving distance of the position data at the preset speed and
acceleration time constant.
Turning RYn2 ON starts a motion in the reverse rotation direction according to the values set to
the selected point table.
