Note 1. Always connect P1 and P2. (Factory-wired.) When using the power factor improving DC reactor, refer to section 12.13. Use only
one of power factor improving DC reactor or power factor improving AC reactor.
2. When using the regenerative option, refer to section 12.2.
3. For the encoder cable, use of the option cable is recommended. Refer to section 12.1 for selection of the cable.
4. For the sink I/O interface. For the source I/O interface, refer to section 3.8.3.
5. Refer to section 3.10.
6. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
7. A cooling fan is attached to the HA-LP6014 and the HA-LP701N4 servo motors. For power supply specification of the cooling
fan, refer to section 3.10.2 (3) (b).
8. Configure the circuit to shut down the main circuit power supply simultaneously with the turn off of emergency stop (EMG) using
the external sequence.
9. Be sure to use a magnetic contactor with an operation delay time of 80ms or less. The operation delay time is the time interval
between current being applied to the coil until closure of contacts.
