Connection of the power regeneration common converter (FR-CV)(01160 or
When connecting the power regeneration common converter (FR-CV), make connection so that the inverter terminals
(P/+, N/-) and the terminal symbols of the power regeneration common converter (FR-CV) are the same.
After making sure that the wiring is correct, set "2" in Pr. 30 Regenerative function selection. (Refer to page 102.)
Remove the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 of the inverter, and connect the
control circuit power supply across terminals R1/L11-S1/L21. Always keep the power input terminals R/
L1, S/L2, T/L3 open. Incorrect connection will damage the inverter. (E.OPT (option fault) will occur. (Refer
to page 278.))
Do not insert an MCCB between the terminals P/+
Opposite polarity of terminals N/-, P/+ will damage the inverter.
Assign the terminal for X10 signal using any of Pr. 178 to Pr. 189 (input terminal function selection).
(Refer to page 110)
Be sure to connect the power supply and terminals R/L11, S/L21, T/MC1.
Operating the inverter without connecting them will damage the power regeneration common converter.
Be sure to connect terminal RDYB of the FR-CV to the X10 signal or MRS signal assigned terminal of the
inverter, and connect terminal SE of the FR-CV to terminal SD of the inverter. Without proper connecting,
FR-CV will be damaged.
