Note 1. Always connect P1 and P2. (Factory-wired.) When using the power factor improving DC reactor, refer to section 11.13.
2. When using the regenerative option, refer to section 11.2.
3. For the encoder cable, use of the option cable is recommended. Refer to section 11.1 for selection of the cable.
4. If deactivating output of trouble (ALM) with parameter change, configure up the power supply circuit which switches off the
magnetic contactor after detection of alarm occurrence on the controller side.
5. For the sink I/O interface. For the source I/O interface, refer to section 3.7.3.
6. Refer to section 3.10.
7. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
8. A cooling fan is attached to the HA-LP6014 and the HA-LP701M4 servo motors. For power supply specification of the cooling
fan, refer to section 3.10.2 (3) (b).
