Torque limit selection disconnecting TL-SG makes internal torque
limit 1 (parameter No. 28) valid and connecting them makes
analog torque limit (TLA) valid.

TL1 When using this signal, make it usable by making the setting of
parameter No. 43 to 48.
For details, refer to (5), Section 3.4.1.
DI-1
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 CN1B

0 0 Stop (servo lock)
01 CCW
10 CW
1 1 Stop (servo lock)
Reverse rotation
start
ST2 CN1B
9
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.
