3.1.3 100 V class
MCCB
1-phase
100 V AC to
120 V AC
(Note 10)
(Note 5) Forced stop 2
(Note 9)
Short-circuit connector
(Packed with the servo amplifier)
Note 1. The power factor improving DC reactor cannot be used.
2. Always connect between P+ and D terminals. (factory-wired) When using the regenerative 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 disabling ALM (Malfunction) output with the parameter, configure up the power supply circuit which switches off the
magnetic contactor after detection of alarm occurrence on the controller side.
5. This diagram is for sink I/O interface. For source I/O interface, refer to section 3.8.3.
6. For connecting 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 magnetic 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 using 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 and L2, use a molded-case circuit breaker. (Refer to
section 11.10.)
11. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
12. 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.
