Note 1. Always connect P1 and P. (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 c able.

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. Cooling fan power supply of the HA-LP11K2 servo motor is 1-phase. Power supply specification of the cooling fan is different

from that of the servo amplifier. Therefore, separate power supply is required.
