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. For the servo amplifiers of 5k and 7kW, always remove the wiring (across P-C) of the built-in regenerative resistor.
3. Refer to the power return converter FR-RC instruction manual (IB(NA)-66330) for the power factor improving reactor to be
used.
When using FR-RC with the servo amplifier of 11k to 22kW, do not use the power factor improving reactor (FR-BEL) together.
4. When using the servo amplifier of 11k to 22kW, make sure to connect P
5. Refer to section 1.3 for the power supply specification.
