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 12.2.
3. For encoder cable, use of the option cable is recommended. Refer to section 12.1 for selection of the cable.
4. For the sink I/O interface. For the source I/O interface, refer to section 3.8.3.
5. Refer to section 3.10.
6. Configure the circuit to shut down the main circuit power supply simultaneously with the turn off of emergency
stop (EMG) using the external sequence.
7. Be sure to use a magnetic contactor with an operation delay time of 80ms or less. The operation delay time is
the time interval between current being applied to the coil until closure of contacts.
