5. OPERATION
2) Forward rotation direction selection (parameter No.PA14)
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.

3) Feed length multiplication selection (parameter No.PA05)
Set the unit multiplication factor (STM) of position data.
Parameter No.PA05 setting
(c) Operation
Choosing the point table using RYnA to RYnE, RY(n 2)3 to RY(n 2)5 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.
