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. For the power factor improving reactor (FR-BAL) to be used, refer to POWER REGENERATION CONVERTER FR-RC
INSTRUCTION MANUAL (IB (NA) 67096). When using FR-BAL with the servo amplifier of 11 k to 22 kW, do not use with the
power factor improving reactor (FR-BAL).
4. When using the servo amplifier of 11k to 22kW, make sure to connect P
1
and P. (Factory-wired.)
5. Refer to section 1.3 for the power supply specification.
