Part 5: Review on Replacement of MR-J2S-30 kW or Higher Capacity Models with MR-J4-DU_
5 - 51
Note 1. For the power supply specifications, refer to Part 7 "Common Reference Material".
2. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80 ms or less. Bus voltage decreases according to the voltage and operation pattern of the main circuit, and there
may be a shift in dynamic brake deceleration during forced stop deceleration. If dynamic brake deceleration is not desired,
delay the time to turn off the electromagnetic contactor.
3. P1 and P2 are connected in factory. When using the power factor improving DC reactor, remove the short-circuit bar across
P1 and P2 before connecting the reactor. For details, refer to Chapter 7 in Part 9.
4. Make sure that the connection destinations of the P/+ terminal and N/- terminal of a brake unit are correct. Otherwise a
malfunction will occur to a converter unit or brake unit.
5. For 400 V class, use a step-down transformer.
6. Contact rating: 1a normally open contact, 5 A at 110 V AC/3 A at 220 V AC
Normal: TH1 and TH2 are disconnected. Abnormal: TH1 and TH2 are connected.
7. Contact rating: 230 V AC_0.3 A/30 V DC_0.3 A
Normal: B and C are connected/A and C are disconnected. Abnormal: B and C are disconnected/A and C are connected.
8. Install an overcurrent protection device (molded-case circuit breaker or fuse) to protect the branch circuit. (Refer to Section 5.3
in Part 5.)
9. Do not connect multiple wires directly to L+ and L- terminals of TE2-1 of a converter unit.
10. Make sure to connect between BUE and SD. (Wired in factory.)
11. Make sure that the connection destinations of MSG terminal and SD terminal of a brake unit are correct. Otherwise a
malfunction will occur to a converter unit or brake unit.
12. Connect L+ and L- terminals of a converter unit to terminal blocks by using wires described in (4) of this section.
13. In order to prevent unexpected restarting of the drive unit, configure the circuit so that EM2 is also turned off when the main
circuit power supply is turned off.
14. This wiring diagram is for MR-J4-DU_B_. The way to interface MR-J4-DU_ is the same as MR-J4-_. Refer to each servo
amplifier instruction manual.
