13.1.10 Power regeneration common converter

When using the power regeneration common converter, set parameter No. 0 to "01
(1) Selection
The power regeneration common converter FR-CV can be used with 750 to 22kW servo amplifiers.
There are the following restrictions on use of the FR-CV.
(a) Up to six servo amplifiers can be connected to one FR-CV.
(b) FR-CV capacity [W] Total of rated capacities [W] of servo amplifiers connected to FR-CV
(c) The total of used servo motor rated currents should be equal to or less than the applicable current
[A] of the FR-CV.
(d) Among the servo amplifiers connected to the FR-CV, the servo amplifier of the maximum capacity
should be equal to or less than the maximum connectable capacity [W].
The following table lists the restrictions.
Item
Maximum number of connected servo amplifiers
Total of connectable servo amplifier capacities [kW]
Total of connectable servo motor rated currents [A]
Maximum servo amplifier capacity [kW]
When using the FR-CV, always install the dedicated stand-alone reactor (FR-CVL).

POINT
For details of the power regeneration common converter FR-CV, refer to
the FR-CV Installation Guide (IB(NA)0600075).
Do not supply power to the main circuit power supply terminals (L
of the servo amplifier. Doing so will fail the servo amplifier and FR-CV.
Connect the DC power supply between the FR-CV and servo amplifier
with correct polarity. Connection with incorrect polarity will fail the FR-
CV and servo amplifier.
Two or more FR-CV's cannot be installed to improve regeneration
capability. Two or more FR-CV's cannot be connected to the same DC
power supply line.
