Note. 0: ST1/ST2-SG off (open)
1: ST1/ST2-SG on (short)
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.
SP1 <Internal speed control mode>
Used to select the command speed for operation.
When using SP1 to SP3, make it usable by making the setting of
parameter No. 43 to 48.

PC Connect PC-SG to switch the speed amplifier from the proportional
integral type to the proportional type.
If the servo motor at a stop is rotated even one pulse due to any
external factor, it generates torque to compensate for a position
shift. When the servo motor shaft is to be locked mechanically after
positioning completion (stop), switching on the proportion control
signal (PC) upon positioning completion will suppress the
unnecessary torque generated to compensate for a position shift.
When the shaft is to be locked for a long time, switch on the
proportion control signal and torque control signal (TL) at the same
time to make the torque less than the rated by the analog torque
limit.
