3. SIGNALS AND WIRING
(1) Using 3-phase 200 V AC to 240 V AC power supply
(a) When not using ALM (Malfunction)
3-phase
200 V AC to
240 V AC
(Note 3) Forced stop 2
Note 1. Be sure to connect between P+ and D terminals (factory-wired). 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 "HG-KN_/HG-SN_ Servo Motor
Instruction Manual".
3. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
4. For connecting servo motor power wires, refer to "HG-KN_/HG-SN_ Servo Motor Instruction Manual".
5. Configure the power supply circuit which switches off the magnetic contactor after detection of alarm occurrence on the
controller side. When using the forced stop deceleration function, shut off the main circuit power supply and turn off the servo-
on command after deceleration to a stop due to an alarm occurrence, an enabled servo forced stop, or an enabled controller
forced stop.
6. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
7. When not using the STO function, attach the short-circuit connector packed with a servo amplifier.
8. 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 11.7.)
9. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
10. 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 power supply voltage and operation pattern, the bus voltage may drop, causing
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.
POINT
Configure the power supply circuit which turns off magnetic contactors of all
servo amplifiers after detection of alarm occurrence on the controller side at
alarm occurrence.
