11.4 Power regeneration converter
POINT
When using the FR-RC-(H) power regenerative converter, refer to "Power
Regeneration Converter FR-RC Instruction Manual (IB(NA)66330)".
When using the power regeneration converter, set "
01" in parameter No.PA02.
(1) Selection
The converters can continuously return 75% of the nominal regenerative power. They are applied to the
servo amplifiers of the 5k to 22kW.

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. Between P
1
and P
2
(P
1
and P for 11kW to 22kW) is connected by default.
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.
7. For selection of power factor improving AC reactors, refer to "Power Regeneration Converter FR-RC Instruction Manual
(IB(NA)66330)".

(4) Mounting hole machining dimensions
When the power regeneration converter is fitted to a totally enclosed type box, mount the heat generating
area of the converter outside the box to provide heat generation measures. At this time, the mounting hole
having the following dimensions is machined in the box.
