• FR-F842-07700(355K) or higher
Regeneration unit
Without regenerative function (FR-CC2)
Brake unit
(FR-CC2+FR-BU2 (MT-BR5))
High power factor converter (FR-HC2)
*1 While the power is supplied only to the control circuit with Pr.30 = "100 or higher", the inverter reset is not performed when the power is supplied
to the main circuit.
 When using a brake unit (FR-BU2, BU, FR-BU) (FR-F820-02330(55K) or
lower, FR-F840-01160(55K) or lower)
• When using the built-in brake, using the FR-BU2 in combination with the GZG/GRZG/FR-BR, or using the BU or FR-BU,
set Pr.30 = "0 (initial value), 10, 20, 100, 110, or 120".
 When using a brake unit (FR-BU2) (FR-F820-03160(75K) or higher,
FRF840-01800(75K) or higher)
• To use the FR-BU2 in combination with the MT-BR5, set as follows.
• Set "1, 11, or 21" in Pr.30.
• Set the brake unit FR-BU2, Pr.0 Brake mode selection = "2".
NOTE
• The stall prevention (overvoltage), oL, does not occur while Pr.30 = "1, 11, or 21".
 When using the power regeneration converter (MT-RC)
• Set "1 or 101" in Pr.30.
 When using the high power factor converter (FR-HC2), multifunction
regeneration converter (FR-XC), power regeneration common converter
(FR-CV), or converter unit (FR-CC2)
• To use the FR-HC2 or FR-CV, set Pr.30 = "2 or 102".
• To use the FR-XC in common bus regeneration mode, set Pr.30 = "2 or 102".
To use the FR-XC in power regeneration mode 1 or 2, set Pr.30 = "0".
• When using the FR-CC2, set Pr.30 = "10" (initial value of the separated converter type).
• Use any of Pr.178 to Pr.189 (Input terminal function assignment) to assign the following signals to the contact input
terminals.
(a) Inverter run enable (X10) signal: FR-HC2 connection, FR-XC connection, FR-CV connection, FR-CC2 connection
To ensure coordinated protection of the FR-HC2, FR-XC (common bus regeneration mode), FR-CV, or FR-CC2, use
the X10 signal to shut off the inverter output.
Input the RDY signal of the FR-HC2 (the RYB signal of the FR-XC, the RDYB signal of FR-CV, or the RDA signal of
FR-CC2).
(b) FR-HC2/FR-CC2 connection, instantaneous power failure detection (X11) signal: FR-HC2 connection, FR-CC2
connection
During the operation using RS-485 communication, with the remote output and analog remote output functions
enabled, the X11 signal is used to store the status when the inverter is set to store the status before an instantaneous
power failure.
Input the FR-HC2/FR-CC2 connection, instantaneous power failure detection signal.
• For the terminal used for the X10 or X11 signal, set "10" (X10) or "11" (X11) in any parameter from Pr.178 to Pr.189 and
assign the function. (For the separated converter type, the X10 signal is assigned to terminal MRS in the initial setting.)
