CN1-43 To start operation, turn on LSP and LSN. Turn it off to bring the motor to a
sudden stop and make it servo-locked.
Setting [Pr. PD30] to " _ _ _ 1" will enable a slow stop.

When LSP or LSN turns off, [AL. 99 Stroke limit warning] occurs, and WNG
(Warning) turns on. When using WNG, enable it by the setting of [Pr. PD23]
to [Pr. PD26], [Pr. PD28], and [Pr. PD47]. However, [Pr. PD47] is not
available with MR-J4-03A6 servo amplifiers.
In the torque control mode, this device cannot be used during normal
operation. It can be used during the magnetic pole detection in the linear
servo motor control mode and the DD motor control mode. Also, when the
magnetic pole detection in the torque control mode is completed, this
signal will be disabled.
CN1-18 Turning off TL will enable [Pr. PA11 Forward torque limit] and [Pr. PA12
Reverse torque limit], and turning on it will enable TLA (Analog torque
limit). For details, refer to section 3.6.1 (5).
To select [Pr. PC35 Internal torque limit 2/internal thrust limit 2], enable
TL1 with [Pr. PD03] to [Pr. PD22]. For details, refer to section 3.6.1 (5).
CN1-17 This is used to start the servo motor.
The following shows the directions.

CN1-18 If both ST1 and ST2 are switched on or off during operation, the servo
motor will be decelerated to a stop according to the [Pr. PC02] setting and
servo-locked.
When " _ _ _1" is set in [Pr. PC23], the servo motor is not servo-locked
after deceleration to a stop.
