Mitsubishi Electric 800 Series Instruction Manual page 70

Common bus regeneration mode with harmonic suppression enabled
(Pr.416 = "1")
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 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 the Instruction Manual (Detailed) of the FR-A800 inverter.)
