12.5 Power regenerative common converter 

POINT 

 

Use the FR-CV for the servo amplifier of 200V class and the FR-CV-H for that of 
400V class. 
For details of the power regenerative common converter FR-CV-(H), refer to the 
FR-CV-(H) Installation Guide (IB(NA)0600075). 
Do not supply power to the main circuit power supply terminals (L

, L

2

, L

) of the 

servo amplifier. Doing so will fail the servo amplifier and FR-CV-(H). 
Connect the DC power supply between the FR-CV-(H) and servo amplifier with 
correct polarity. Connection with incorrect polarity will fail the FR-CV-(H) and servo 
amplifier. 
Two or more FR-CV-(H)'s cannot be installed to improve regeneration capability. 
Two or more FR-CV-(H)'s cannot be connected to the same DC power supply line.

 

 
When using the power regenerative common converter, set parameter No.PA02 to "

01".

(2) Selection 

The power regenerative common converter FR-CV can be used for the servo amplifier of 200VAC class 
with 750 to 22kW and that of 400VAC class with 11k to 22kW. The following shows the restrictions on using 
the FR-CV-(H). 

 

(a) Up to six servo amplifiers can be connected to one FR-CV-(H). 

 

(b) FR-CV-(H) capacity [W] Total of rated capacities [W] of servo amplifiers connected to FR-CV-(H). 

 

(c) The total of used servo motor rated currents should be equal to or less than the applicable current [A] of 

the FR-CV-(H). 

 

(d) Among the servo amplifiers connected to the FR-CV-(H), the servo amplifier of the maximum capacity 

should be equal to or less than the maximum connectable capacity [W].
