Note 1. Always connect P
1
and P
2
. (Factory-wired.) When using the power factor improving DC reactor, refer to section 14.11.
2. Connect the regenerative resistor. When using the regenerative option, refer to section 14.2.
3. For encoder cable, use of the option cable is recommended. Refer to section 14.1 for selection of the cable.
4. For the sink I/O interface. For the source I/O interface, refer to section 4.8.3.
5. Refer to section 4.10.
6. Servo amplifiers do not have BW when the cooling fan power supply is 1-phase.
7. For the cooling fan power supply, refer to section 4.10.2 (3) (b).
8. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
9. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
10. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80ms or less.
11. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at emergency stop. Ensure the safety in the entire equipment.
