Mitsubishi Electric MELSERVO MR-J5 Series User Manual page 68

*1 To prevent an electric shock, connect the protective earth (PE) terminal (the terminal marked with the symbol) of the servo amplifier to
the protective earth (PE) of the cabinet.
*2 Connect the diode in the correct direction. If it is connected reversely, the servo amplifier may malfunction and not output signals,
disabling protective circuits such as EM2 (Forced stop 2).
*3 If the controller does not have the forced stop function, install a forced stop switch (normally closed contact).
*4 When starting operation, always turn on EM2 (Forced stop 2). (normally closed contact)
*5 Use SW1DNC-MRC2-_.
*6 Use SSCNET III cables listed in the following table.
Cable
Standard cord inside cabinet
Standard cable outside cabinet
Long distance cable
*7 The wiring after the second servo amplifier is omitted.
*8 Up to 64 axes of servo amplifiers can be connected. The number of connectable axes depends on the specifications of the controller
being used. For the axis selection setting, refer to "Switch setting and display of the servo amplifier" in the User's Manual (Introduction).
*9 Supply 24 V DC ± 10 % to interfaces from an external source. The total current capacity of these power supplies is 350 mA maximum for
the MR-J5W2-_B and 450 mA maximum for the MRJ5W3-_B. These values are applicable when all I/O signals are used. Reducing the
number of I/O points decreases the current capacity. For the current required for interfaces, refer to the following.

Although the diagram shows the input signal and the output signal each using a separate 24 V DC power supply for illustrative purposes,
the system can be configured to use a single 24 V DC power supply.
*10 CALM (AND malfunction) turns on in a normal state where no alarms have occurred. (normally closed contact)
*11 In the initial setting, CINP (AND in-position) is assigned to this pin. The device of the pin can be changed with [Pr. PD08].
*12 The devices of these pins can be changed with [Pr. PD07] and [Pr. PD09].
*13 Devices can be assigned to these pins with the controller setting. For the setting method, refer to each controller manual.
*14 To prevent an unexpected restart of the servo amplifier, configure a circuit that turns off EM2 when the main circuit power supply is
turned off.
*15 If not using the STO function, attach the short-circuit connector that came with the servo amplifier.
*16 This pin cannot be used on MR-J5 2-axis servo amplifiers.
*17 The diagram is for the MR-J5 3-axis servo amplifier.
*18 This signal cannot be used for the MR-J5W3-_B.
*19 When using a linear servo motor or direct drive motor, use MBR (Electromagnetic brake interlock) for the external brake mechanism.
*20 This device is used for forced stop of the servo amplifier (common to all axes). Perform an emergency stop of the whole system on the
controller side.
*21 Cover the unused CN1B connector with a cap.
