Note 1. Always connect P1 and P2. (Factory-wired.) When using the power factor improving DC reactor, refer to section 14.11.

2. Always connect P and D. (Factory-wired.) When using the regenerative option, refer to section 14.2.

3. For 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. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
