. (Factory-wired.) When using the power factor improving DC reactor, refer to Section 11.13.
2. When using the regenerative brake 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. There is no BW if HA-LP11K24 is used.
8. For the cooling fan power supply, refer to (3) (b) in Section 3.10.2.
