Connection Of The Multifunction Regeneration Converter (Fr-Xc) - Mitsubishi Electric FR-A800 Series 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
72.)
• 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.
2.10.6 Connection of the multifunction regeneration
 Common bus regeneration mode with harmonic suppression disabled
(Pr.416 = "0")
When connecting the multifunction regeneration converter (FR-XC) to improve the braking capability, perform wiring securely
as follows. Failure to do so will damage the converter and the inverter.
Turn ON switch 1 (connection mode setting switch) in the function selection switch assembly (SW2). If the switch setting does
not match the actual wiring, the connection mode fault "E.T" occurs.
