Note 1. To prevent an electric shock, always connect the protective earth
(PE) terminal (terminal marked
protective earth (PE) of the control box.
2. Connect the diode in the correct direction. If it is connected
reversely, the servo amplifier or the MR-J3-D01 will be faulty and
will not output signals, disabling the forced stop (EMG) and other
protective circuits.
3. The forced stop switch (normally closed contact) must be installed.
4. Supply 24VDC 10% 150 mA current for interfaces of the servo
amplifier from the outside. 150 mA is the value applicable when
all I/O signals are used. The current capacity can be decreased by
reducing the number of I/O points. Refer to section 3.8.2 (1) of "MR-
J3-_T/MR-J3-D01 Servo Amplifier Instruction Manual" that gives the
current value necessary for the interface."MR-J3-_T/MR-J3-D01
5. When starting operation, always turn on forced stop (EMG) and
Forward/Reverse rotation stroke end (LSP/LSN). (Normally closed
contacts)
6. Trouble (ALM) turns on in normal alarm-free condition.
7. Use MRZJW3-SETUP 211E.
8. Personal computers or parameter modules can also be connected
via the CN3 connector, enabling RS-422 communication.
Note that using the USB communication function (CN5 connector)
prevents the RS-422 communication function (CN3 connector) from
being used, and vice versa. They cannot be used together.

9. For the sink I/O interface. For the source I/O interface, refer to
section 3.8.3 of "MR-J3-_T/MR-J3-D01 Servo Amplifier Instruction
Manual".
10. In this case, select a power supply capacity suitable for the number
of input and output signals used. One 24 V DC power supply can be
used for the input and output signals and the servo amplifier.

Short-circuit connector
(Packed with the servo amplifier)
Note 1. To prevent an electric shock, always connect the protective earth
(PE) terminal (marked
earth (PE) of the cabinet.
2. Connect the diode in the correct direction. If it is connected
reversely, the servo amplifier will malfunction and will not output
signals, disabling EM2 (Forced stop 2) and other protective circuits.
3. The forced stop switch (normally closed contact) must be installed.
4. Supply 24 V DC ± 10% to interfaces from outside. The total current
capacity is up to 500 mA. 500 mA is the value applicable when all
I/O signals are used. The current capacity can be decreased by
reducing the number of I/O points. Refer to section 3.9.2 (1) of
"MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual" that gives the
current value necessary for the interface. A 24 V DC power supply
can be used for both input signal and output signal.
5. When starting operation, always turn on EM2 (Forced stop 2), LSP
(Forward rotation stroke end) and LSN (Reverse rotation stroke
end) (normally closed contact).
6. ALM (Malfunction) turns on in normal alarm-free condition (normally
closed contact).
7. The pins with the same signal name are connected in the servo
amplifier.
8. TLA will be available when TL (External torque limit selection) is
enabled with [Pr. PD04], [Pr. PD06], [Pr. PD08], [Pr. PD10], [Pr.
PD12], [Pr. PD14], [Pr. PD18], [Pr. PD20], [Pr. PD22], [Pr. PD44],
and [Pr. PD46]. (Refer to section 3.6.1 (5) of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual".)
9. Use SW1DNC-MRC2-_. (Refer to section 11.7 of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual".)
10. Controllers or parameter units can also be connected via the CN3
connector with the RS-422/RS-485 communication. Note that using
the USB communication function (CN5 connector) prevents the RS-
422 communication function (CN3 connector) from being used, and
vice versa. They cannot be used together.
