Functions/Applications
I/O
division
ST
Used to start the servo motor in any of the following directions:
(Note) Input signals
ST2 ST1
Servo motor starting direction
Forward rotation
start
ST1 CN1
-3
0 0 Stop (servo lock)
0 1 CCW
10 CW
1 1 Stop (servo lock)
Reverse rotation

ST2 CN1
-5
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.
DI-1
Used to select any of the following servo motor torque generation
directions:
(Note) Input signals
RS2 RS1
