11. OPTIONS AND AUXILIARY EQUIPMENT
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].
