Display (Note 2) Servo amplifier status and alarm number are displayed.

Station number setting part (Note 2) Select the station with the station number selection rotary switches (SW2 and SW3). USB communication connector (CN5) Connect with a personal computer, and use MR Configurator2. Parameter setting and monitoring are possible. Use an optional USB cable (MR-J3USBCBL3M).

Molded-case circuit breaker (MCCB) This protects the power supply line.

STO I/O signal connector (CN8)

Magnetic contactor (MC) This turns off the main circuit power supply to the servo amplifier when an alarm is triggered. Power factor improving DC reactor (option) This boosts the power factor of servo amplifier and reduces the power supply capacity.

Connect MR-J3-D05 safety logic unit or an external safety relay. Use an option STO cable (MR-D05UDL3M-B).

I/O signal connector (CN3) Connect the forced stop input, the in-position, the electromagnetic brake interlock, and the malfunction signals.

Regenerative option (option)

Servo motor power cable (option)

Ethernet cable (Note 3)

Battery connector (CN4) Connect MR-BAT6V1SET-A battery when configuring absolute position detection system. CN2L connector is available only on MR-J4-GF-RJ servo amplifier. Refer to pp. 1-31 to 1-36 in this catalog for the connection. Load-side encoder connector (CN2L) Charge lamp The lamp lights when the main circuit power supply is charged. Encoder connector (CN2) Connect the servo motor encoder using an option cable or connector set.

Notes: 1. The connection with the peripheral equipment is an example for MR-J4-350GF/MR-J4-350GF-RJ or smaller servo amplifiers. Refer to "MR-J4-_GF_(-RJ) Servo Amplifier Instruction Manual (Motion Mode)" for the actual connections. 2. This picture shows when the display cover is open. 3. For specifications of the Ethernet cable, refer to "Ethernet Cable Specifications" on p. 5-31 in this catalog.
