11.5.2 Selection example
(1) 200 V class
FR-CV power regeneration common converter can be used for the 200 V class servo amplifier of 100 W
to 22 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.
