12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 5
Note 1. To prevent an electric shock, be sure to 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 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-_C 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. When LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end) are not assigned to the input devices, set
automatic on for LSP and LSN in [Pr. PD01 Input signal automatic on selection]. When assigning to the input devices, set with
[Pr. PD05 Input device selection 1L] to [Pr. PD28 Input device selection 8H].
6. ALM (Malfunction) turns on in normal alarm-free condition (normally closed contact).
7. Use SW1DNC MRC2-_. (Refer to section 11.4 of "MR-JE-_C Servo Amplifier Instruction Manual".)
8. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
9. Recommended device assignments are shown. The devices can be changed with [Pr. PD29 Output device selection 1] to [Pr.
PD32 Output device selection 4].
10. For communication function, refer to the "MR-JE-_C Servo Amplifier Instruction Manual (Network)".
11. Modbus/TCP can be used on servo amplifiers with software version A3 or later. Modbus RTU can be used on servo amplifiers
with software version A4 or later.
12. Ethernet communication (CC-Link IE field network Basic, SLMP, and Modbus/TCP) and RS-485 communication (Modbus
RTU) are exclusively independent functions. Only the communication function selected in [Pr. PN08] "Communication function
selection" can be used.
13. If the servo amplifier to be connected is the last axis, terminate the servo amplifier with a 150 Ω resistor between DA and DB.
For wiring, refer to "MR-JE-_C Servo Amplifier Instruction Manual (Network)".
14. When CN3-6 and CN3-19 pins are used as the input devices of sink interface, of 24 V DC to CN3-18 pin (OPC:
power input for open-collector sink interface).
