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 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. Refer to section 1.2 for the power supply specification.
