Note 1. Always connect P1 and P2. (Factory-wired.) The power factor improving DC reactor cannot be used.

2. Always connect P and D. (Factory-wired.) 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.
