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 the 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. BW is not available when a 1-phase power supply is used.
7. For the cooling fan power supply, refer to section 4.10.2 (3) (b).
8. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
9. 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.
10. 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.
