Used to start the servo motor in any of the following directions:
(Note) Input signals
ST2 ST1

Note.0: OFF (ST1/ST2-SG open)
1: ON (ST1/ST2-SG shorted)
If both ST1 and ST2 are switched on or off during operation, the
servo motor will be decelerated to a stop according to the
parameter No. 12 setting and servo-locked. When the analog
speed command (VC) is 0V, starting the servo motor will not
generate servo lock torque.
