Power supply
Note 1. When not using the phase detection terminals, fit the jumpers across RX-R, SX-S and TX-T. If the jumpers remain
removed, the FR-RC-(H) will not operate.
2. When using servo amplifiers of 5kW and 7kW, always remove the lead of built-in regenerative resistor connected
to P terminal and C terminal.
3. When setting not to output Trouble (ALM) with parameter change, configure power supply circuit for turning
magnetic contactor off after detecting an occurrence of alarm on the controller side.
4. Always connect P

2
(For 11k to 22kW, connect P
1
-P). (Factory-wired.) When using the power factor improving
DC reactor, refer to section 11.13.
5. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class in 400V class servo
amplifiers.
6. Refer to section 1.3 for the power supply specification.
