Connection of the power regeneration common converter (FR-CV)
When connecting the power regeneration common converter (FR-CV), connect the inverter terminals (P/+ and N/-) and power
regeneration common converter (FR-CV) terminals as shown below so that their symbols match with each other.
MC
MCCB
Three-phase
AC power supply
Do not connect anything to the input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the inverter.
Do not insert an MCCB between the terminals P/+ and N/- (between P/L+ and P/+, between N/L- and N/-). Opposite polarity of terminals
N/- and P/+ will damage the inverter.
Always 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.
Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10 and RES signals. (Refer to page 134)
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.
NOTE
The voltage phases of the FR-CV terminals R/L11, S/L21, and T/MC1 and the voltage phases of the inverter terminals
R2/L1, S2/L2, and T2/L3 must be matched.
Use sink logic (initial setting) when the FR-CV is connected. The FR-CV cannot be connected when source logic is
selected.
Do not connect a DC reactor (FR-HEL) to the inverter when FR-CV is connected.
Filterpack connection is not available when FR-CV is connected.
