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

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)".

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.

11.5 Power regeneration common converter
POINT
Use the FR-CV for the servo amplifier of 200V class and the FR-CV-H for that
of 400V class.
For details of the power regeneration common converter FR-CV-(H), refer to
the FR-CV-(H) Installation Guide (IB(NA)0600075).
Do not supply power to the main circuit power supply terminals (L
1
, L
2
, L
3
) of
the servo amplifier. Doing so will fail the servo amplifier and FR-CV-(H).
Connect the DC power supply between the FR-CV-(H) and servo amplifier
with correct polarity. Connection with incorrect polarity will fail the FR-CV-(H)
and servo amplifier.
Two or more FR-CV-(H)'s cannot be installed to improve regeneration
capability. Two or more FR-CV-(H)'s cannot be connected to the same DC
power supply line.
When using the power regeneration common converter, set parameter No.PA02 to "
01".

(2) Selection
The power regenerative common converter FR-CV can be used for the servo amplifier of 200V class with
750 to 22kW and that of 400V class with 11k to 22kW. The following shows the restrictions on using the
FR-CV-(H).
(a) Up to six servo amplifiers can be connected to one FR-CV-(H).
(b) FR-CV-(H) capacity [W] Total of rated capacities [W] of servo amplifiers connected to FR-CV-(H) 2
(c) The total of used servo motor rated currents should be equal to or less than the applicable current [A] of
the FR-CV-(H).
(d) Among the servo amplifiers connected to the FR-CV-(H), the servo amplifier of the maximum capacity
should be equal to or less than the maximum connectable capacity [W].
