2.11.5
Connection of the multifunction regeneration
converter (FR-XC)
Common bus regeneration mode with harmonic suppression disabled
(Pr.416 = "0")
When connecting the multifunction regeneration converter (FR-XC) to suppress power harmonics, perform wiring securely as
follows. Incorrect connection will damage the multifunction regeneration 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.
After making sure that the wiring is correct and secure, set "2 or 102" in Pr.30 Regenerative function selection. (Refer to the
Instruction Manual (Detailed) of the FR-A800 inverter.)
