Configure the wirings so that the main circuit power supply is shut off and SON (Servo-on) is turned off after
deceleration to a stop due to an alarm occurring, enabled servo forced stop, etc.

Note 1. Use reinforced insulating type for 24 V DC and 48 V DC power supply.
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 is for the sink I/O interface. For source I/O interface, refer to section 3.9.3.
4. For connecting servo motor power wires, refer to "Servo Motor Instruction Manual (Vol. 3)".
5. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the
servo amplifier.
6. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
7. The illustration of the 24 V DC power supply is divided between input signal, output signal, and external emergency
stop circuit for convenience. However, they can be configured by one. For 24 V DC power for I/O signal, use power
other than 24 V DC power of servo amplifier control circuit power supply.
8. The noiseless grounding (
) terminals and E terminals are connected in the servo amplifier. Be sure to ground
from the noiseless grounding (
) terminal of CNP1 to the grounding terminal of the cabinet.
9. Circuit protectors are required for protection of power supplies, wires, servo amplifiers and others. When not using
a circuit protector, configure an external protective circuit such as a power supply with protection function.
