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 amplifier of 5kW and 7kW, always remove the lead of built-in regenerative resistor connected to P terminal
and C terminal.
3. For sink input-output interface. Refer to section 3.8.3 for source input-output interface.
4. Always connect P

). (Factory-wired.) When using the power factor improving DC reactor,
refer to section 12.13.
5. For 400VAC class, the stepdown transformer is required.
6. For the specification of power supply, refer to section 1.3.
