After making sure that the wiring is correct and secure, set "2" in Pr.30 Regenerative function selection. (Refer to
Three-phase
AC power
supply
*1 Remove jumpers across terminals R/L1 and R1/L11 as well as across terminals 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, and T/L3). Incorrect connection will damage
the inverter. (The E.OPT fault (option fault) occurs. (Refer to
*2 Do not install an MCCB across 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.
*3 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 signal. (Refer to
*4 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.
*5 Always connect terminal RDY on the FR-HC2 to a terminal where the X10 signal or MRS signal is assigned on the inverter. Always connect
terminal SE on the FR-HC2 to terminal SD on the inverter. 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 the FR-CV is connected.
