11.5 FR-CV Power regenerative common converter
POINT
For details of the power regenerative common converter FR-CV, refer to the FR-
CV-(H) Installation Guide (IB(NA)0600075).
Do not supply power to the main circuit power supply terminals (L1, L2, and L3)
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.
When using FR-CV, set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1).
When using the power regenerative common converter, set [Pr. PA02] to "_ _ 0 1".

(2) Selection example
The power regenerative common converter FR-CV can be used for the servo amplifier of 200 V class
with 750 W to 7 kW. The following shows the restrictions on using 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] × 2 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.
