11. MR-D01 EXTENSION I/O UNIT
11 - 32
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) 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 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 of these power supplies must be 500 mA or lower.
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 "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual" section 11.7.)
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/RS-485 communication function (CN3
connector) from being used, and vice versa. They cannot be used together.

11. Use an external power supply when inputting a negative voltage.
12. When not using the STO function, attach the short-circuit connector came with a servo amplifier.
13. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
14. The CN1-10 pin, CN1-12 pin, and CN1-35 pin cannot be used with source input interfaces.
15. The devices can be changed with [Pr. PD04], [Pr. PD06], [Pr. PD08], [Pr. PD10], [Pr. PD12], [Pr. PD14], [Pr. PD18], [Pr.
PD20], [Pr. PD22], [Pr. PD44], and [Pr. PD46].
16. Output devices are not assigned by default. Assign the output devices with [Pr. PD47] as necessary.
17. Recommended device assignments are shown. The devices can be changed by [Pr. PD23] to [Pr. PD26], and [Pr. PD28].
18. DI2 and DI3 are assigned to the CN1-10 and CN1-35 pins by default. When connecting a manual pulse generator, change
them with [Pr. PD44] and [Pr. PD46]. Refer to section 9.1 for details of the manual pulse generator.
19. of 24 DC V to OPC (Power input for open-collector sink interface) when input devices are assigned to the CN1-10 pin
and the CN-35 pin. They cannot be used with source input interface. For the positioning mode, input devices (DI2 and DI3) are
assigned with the initial values.
20. Supply 24 V DC ± 10% to interfaces of the MR-D01 from outside. The total current capacity of these power supplies must be
800 mA or lower. 800 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. For the current required for the interface, refer to section 3.8.2 (1) of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual".
21. As the 24 V DC for the input/output signals, one 24 V DC power supply can be used to supply to the servo amplifier and MR-
D01. In this case, select an appropriate power supply capacity depending on the number of points of the input/output signals to
be used.
22. The CN1-2 pin and CN20-2 pin are exclusive. The CN1-2 pin is set by default. Select this item with [Pr. Po11].
23. The CN1-27 pin and CN20-12 pin are exclusive. The CN1-27 pin is set by default. Select this item with [Pr. Po11].
24. When using program No. selection 3 and program No. selection 4 with a source input interface, configure the circuit as shown
in the figure.
