Operation start-up ST (CN3-10) Use this device for the positioning function by the operation start-up signal.
For details, refer to the MR-J4-_TM_ Servo Amplifier Instruction Manual for
each communication method.

Forward rotation
stroke end LSP CN3-2 To start the operation, turn on LSP and LSN. Turn it off to bring the servo motor
to a slow stop and make it servo-locked. DI-1

Setting [Pr. PD01] as follows turn the signals on automatically (always
connected) in the servo amplifier.

When LSP or LSN is turned off, [AL. 99 Stroke limit warning] occurs.
In the torque 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 mode is completed, this signal will be disabled.
Proximity dog DOG CN3-19 Turning off DOG will detect a proximity dog. The polarity for dog detection can
be changed with [Pr. PT29].

Proportional control PC Turn PC on 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 PC (Proportion control) 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 PC (Proportion
control) at the same time to make the torque less than the rated one.
Do not use PC (Proportional control) in the torque mode. When PC
(Proportional control) is used in the torque mode, operation may be performed
at a speed exceeding the speed limit value. DI-1
Gain switching CDP Turn on CDP to use the values of [Pr. PB29] to [Pr. PB36] and [Pr. PB56] to [Pr.
PB60] as the load to motor inertia ratio and gain values. DI-1
Fully closed loop
selection CLD This is used when the semi closed loop control/fully closed loop control
switching is enabled with [Pr. PE01].
Turn off CLD to select the semi closed loop control, and turn on CLD to select
the fully closed loop control. DI-1
