limit selection
TL CN1-18 Turn TL off to make Forward torque limit (parameter No.PA11) and
Reverse torque limit (parameter No.PA12) valid, or turn it on to
make Analog torque limit (TLA) valid.
For details, refer to section 3.6.1 (5).

limit selection
TL1 When using this signal, make it usable by making the setting of
parameter No.PD03 to PD08, PD10 to PD12.
For details, refer to section 3.6.1 (5).
DI-1
Forward rotation
start
ST1 CN1-17 Used to start the servo motor in any of the following directions.

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.PC02 setting and servo-locked.
When "
1" is set in parameter No.PC23, the servo motor is not
servo-locked after deceleration to a stop.
