13.1.10 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 (L1, L2,
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 the power regeneration common converter, set parameter No. 0 to "01
".
(1) Selection
The power regeneration common converter FR-CV can be used with 750W 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 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.
(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.
