3. SIGNALS AND WIRING
3 - 4
Note 1. Between P+ and D is connected by default. When using the regenerative option, refer to section 11.2.
2. For the encoder cable, use of the option cable is recommended. For selecting cables, refer to Servo Motor
Instruction Manual (Vol. 3).
3. This circuit is an example of stopping all axes when an alarm occurs. If disabling CALM (AND 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.
4. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
5. For connecting servo motor power wires, refer to Servo Motor Instruction Manual (Vol. 3).
6. 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.
7. For 1-phase 200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open. For power supply
specifications, refer to section 1.3.
8. Configure up 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 a short-circuit connector supplied 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. For the MR-J4 3-axis servo amplifier
12. Connecting a servo motor for different axis to the CNP3A, CNP3B, or CN3C connector may cause a malfunction.
13. 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.
