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. 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.
