Note 1. Always connect P and D. When using the regenerative option, refer to section 11.2.
2. For the encoder cable, use of the option cable is recommended. Refer to section 11.1 for selection of the cable.
3. If deactivating output of malfunction (ALM-A/ALM-B) with parameter change, configure up the power supply circuit which switches
off the magnetic contactor after detection of alarm occurrence on the controller side. In this connection example, the operation
continues in the other axis when an alarm occurs in the A-axis or the B-axis. To stop both axes in an alarm occurrence, connect
RA1 and RA2 in series.
4. For the sink I/O interface. For the source I/O interface, refer to section 3.7.3.
5. For the power line connection, refer to section 3.10.
6. Configure the circuit to shut down the main circuit power supply simultaneously with the turn off of forced stop (EM1) using the
external sequence.
7. This connection example is a connection using a rotary servo motor. Turn SW3 off (factory setting). (Refer to section 3.14.)
8. 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.
9. For 1-phase 200V to 230VAC, connect the power supply to L

and leave L

open. Refer to section 1.3 for the power supply
specification.
10. Connecting a servo motor for different axis to the CNP3A or CNP3B connector may cause a malfunction.
