Note 1. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar
between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor
improvin
g
AC reactor cannot be used simultaneousl
y
.
2. When usin
g
the re
g
enerative option, refer to section 11.2.
3. For the encoder cable, use of the option cable is recommended. For selecting cables, refer to "Servo Motor Instruction Manual
(
Vol. 3
)
".
4. If ALM (Malfunction) output is disabled with the parameter, configure up the power supply circuit which switches off the
ma
g
netic contactor after detection of alarm occurrence on the controller side.
5. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3 in MR-J4-_B(-RJ) Servo Amplifier
Instruction Manual.
6. For connectin
g
servo motor power wires, refer to "Servo Motor Instruction Manual
(
Vol. 3
)
".
7. 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, slow the time to turn off the ma
g
netic contactor.
8. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
9. When not usin
g
the STO function, attach the short-circuit connector came with a servo amplifier.
10. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker. (Refer to
section 11.10.
)
11. Connectin
g
a servo motor for different axis to U, V, W, or CN2 of the servo amplifier ma
y
cause a malfunction.
12. Stepdown transformer is required for coil volta

13. For the servo motor with a coolin
g
fan.
14. For the coolin

, refer to "Servo Motor Instruction Manual

)
".
15. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be confi

one.
16. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the
safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to chapter 8. For wiring
of the external d
y
namic brake, refer to section 11.17.
17. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake
interlock) in [Pr. PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an
instantaneous power failure occurs.
18. Do not
g
round L11 and L21.
