Note 1. Always 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 cable selection, 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 3.9.3.
4. For connection of servo motor power wires, refer to "HG-KN/HG-SN Servo Motor Instruction Manual".
5. 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, bus voltage can decrease.
This can shift the mode to the dynamic brake deceleration during forced stop deceleration. When dynamic brake
deceleration is not required, slow the time to turn off the magnetic contactor.
6. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
7. Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
8. 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.
POINT
Connect the 1-phase 200 V AC to 240 V AC power supply to L1 and L2. One of
the connecting destinations is different from MR-JE-100A or less Servo
Amplifier's.
You can use the neutral point of a 3-phase 400 V AC class power supply to
input a 1-phase 200 V AC class power supply to the servo amplifier. Refer to
app. 7 for details.
