2. SIGNALS AND WIRING
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked
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 300 mA or lower.
300 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-JE-_A Servo Amplifier Instruction Manual" that gives the current value
necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output signal for
convenience. However, they can be configured by one.
5. ALM (Malfunction) turns on in normal alarm-free condition (normally closed contact).
6. The pins with the same signal name are connected in the servo amplifier.
7. TLA will be available when TL (External torque limit selection) is enabled with [Pr. PD03], [Pr. PD11], [Pr. PD13], [Pr. PD17],
and [Pr. PD19]. (Refer to section 3.6.1 (5) of "MR-JE-_A Servo Amplifier Instruction Manual".)
8. Use SW1DNC MRC2-_. (Refer to section 11.4 of "MR-JE-_A Servo Amplifier Instruction Manual".)
9. To prevent an unexpected restart of the servo amplifier, configure a circuit to turn off EM2 when the power is turned off.
10. The USB communication function and RS-422/RS-485 communication function are mutually exclusive. They cannot be used
together.
11. Recommended device assignments are shown. The device can be changed by [Pr. PD24] to [Pr. PD25], and [Pr. PD28].
12. MD0 and DOG 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.
13. Supply + 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 (MD0 and DOG)
are assigned by default.
