2.8.4
When connecting the high power factor converter (FR-HC2) to suppress power harmonics, perform wiring securely as follows.
Incorrect connection will damage the high power factor converter and the inverter.
After making sure that the wiring is correct and secure, set the rated motor voltage in Pr.19 Base frequency voltage (under
V/F control) or Pr.83 Rated motor voltage (under other than V/F control) and "2 or 102" 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 Instead of connecting the terminals to the AC power supply, the control circuit can be powered by connecting terminal R1/L11 to terminal P/+ and
terminal S1/L21 to terminal N/-. In this case, do not connect the terminals to the AC power supply. Doing so will damage the inverter.
*3 When the FR-HC2 is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-HC2 can be connected with the
jumper connected (initial setting). Refer to
*4 Do not install an MCCB across terminals P/+ and N/- (between terminals P and P/+ or between terminals N and N/-). Connecting the opposite
polarity of terminals N/- and P/+ will damage the inverter.
*5 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 (X11) signal. (Refer to
For RS-485 or any other communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the
time of an instantaneous power failure.
*6 Assign the IPF signal to a terminal on the FR-HC2. (Refer to the FR-HC2 Instruction Manual.)
*7 Always connect terminals R/L1, S/L2, and T/L3 on the FR-HC2 to the power supply. Operating the inverter without connecting them will damage
the FR-HC2.
*8 Do not install an MCCB or MC across terminals (R/L1, S/L2, T/L3) on the reactor 1 and terminals (R4/L14, S4/L24, T4/L34) on the FR-HC2. Doing
so disrupts proper operation.
*9 Securely perform grounding (earthing) by using the grounding (earthing) terminal.
*10 Installation of a fuse is recommended. (Refer to the FR-HC2 Instruction Manual.)
*11 Outside box is not available for the FR-HC2-H280K or higher. Connect filter capacitors, inrush current limit resistors, and magnetic contactors.
(Refer to the FR-HC2 Instruction Manual.)
NOTE
• The voltage phases of terminals R/L1, S/L2, and T/L3 and the voltage phases of terminals R4/L14, S4/L24, and T4/L34 must
be matched.
• The control logic (sink logic/source logic) of the high power factor converter and the inverter must be matched. (Refer to
64.)
• Do not connect a DC reactor (FR-HEL) to the inverter when the FR-HC2 is connected.
CAUTION
• 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-HC2.
