14.5 Power regeneration common converter
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
1
, L
2
, L
3
) 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 the power regeneration common converter, set parameter No. PA02 to " 01".
(1) Model
Applicable servo amplifier capacity [kW]
(2) Selection
The power regenerative common converter FR-CV can be used for the servo amplifier of 200VAC class
with 750W to 22kW. 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] of servo amplifiers connected to FR-CV2.
(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.
