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 (L
1, 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 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 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.
