App. 15 When using the servo amplifier with the DC power supply input

App. 15.1 Connection example
CAUTION
For the signal and wirings not given in this section, refer to section 3.1.1 to 3.1.3.
(1) MR-J4-10B-RJ to MR-J4-100B-RJ
3-phase or 1-phase
200 V AC to 240 V AC
(Note 2) Forced stop 2
Note 1. For the power supply specifications, refer to section 1.3.
2. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
3. 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. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may
cause the forced stop deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not
required, delay the time to turn off the magnetic contactor.
4. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
5. When not using the STO function, attach the short-circuit connector came with a servo amplifier.
6. 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.
7. Driving the on switch and off switch with the DC power supply meets IEC/EN 60204-1 requirements.
8. Do not use the 24 V DC interface power supply for the magnetic contactor DC power supply. Always use the power supply
designed exclusively for the magnetic contactor.
9. If disabling ALM (Malfunction) output with the parameter, configure the power supply circuit which switches off the magnetic
contactor after detection of alarm occurrence on the servo system controller side.
10. When wires used for L11 and L21 are thinner than wires used for L1 and L3, use a fuse. (Refer to app. 15.4.)
POINT
The DC power supply input is available with MR-J4-_B-RJ servo amplifiers with
software version C2 or later.
When using the MR-J4-_B-RJ servo amplifier with the DC power supply input,
set [Pr. PC20] to "_ _ _ 1".
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.
