Connection Of The Power Regeneration Common Converter (Fr-Cv) - Mitsubishi Electric FR-F800 Instruction Manual

2.8.5
Connection of the power regeneration common
converter (FR-CV)
When connecting the power regeneration common converter (FR-CV), connect the inverter terminals (P/+, N/-) and the power
regeneration common converter (FR-CV) terminals as shown below so that their symbols match with each other.
The FR-CV is applicable to FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
After making sure that the wiring is correct, set "2" in Pr.30 Regenerative function selection. (Refer to


Remove jumpers between terminals R/L1 and R1/L11 as well as between S/L2 and S1/L21, and connect the power supply for the
control circuit to terminals R1/L11 and S1/L21. Do not connect anything to power input terminals (R/L1, S/L2, T/L3). Incorrect
connection will damage the inverter. (E.OPT (option fault) will occur. (Refer to

Do not insert an MCCB between terminals P/+ and N/- (between terminals P/L+ and P/+ or between N/L- and N/-). Connecting the
opposite polarity of terminals N/- and P/+ will damage the inverter.

Use Pr.178 to Pr.189 (input terminal function selection) to assign the terminals used for the X10 signal. (Refer to

Be sure to connect the power supply and terminals R/L11, S/L21, and T/MC1. Operating the inverter without connecting them will
damage the power regeneration common converter.

Always connect terminal RDYB of the FR-CV to the inverter terminal where the X10 signal or the MRS signal is assigned to. Always
connect terminal SE of the FR-CV to the inverter terminal SD. Not connecting these terminals may damage the FR-CV.
NOTE
• The voltage phases of terminals R/L11, S/L21, and T/MC1 and the voltage phases of terminals R2/L1, S2/L2, and T2/L3 must
be matched.
• Use the sink logic (factory setting) when the FR-CV is connected. It cannot be connected when the source logic is selected.
• Do not connect a DC reactor (FR-HEL) to the inverter when FR-CV is connected.
