4. OPERATION
(b) ST1 coordinate system selection (parameter No.1)
Choose the servo motor rotation direction at the time when the forward rotation start (ST1) signal
or reverse rotation start (ST2) signal is switched on.
Parameter No.1 setting
ST1:ON
CCW
(c) Feed length multiplication selection (parameter No.1) Set the unit multiplication factor (STM) of
position data.
Parameter No.1 setting
(3) Operation
Choose the point table using DI0 to DI4 and short ST1-SG to make a motion in the forward rotation
direction over the distance of the position data under the conditions of the preset speed, acceleration
time constant and deceleration time constant. Short ST2-SG to make a motion in the reverse rotation
direction in accordance with the point table settings.
