• FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher
Regeneration unit
Without regenerative function
Brake unit (FR-BU2 (MT-BR5))
Power regeneration converter (MT-RC)
High power factor converter (FR-HC2)
Multifunction regeneration converter
(FR-XC) (power regeneration mode 1 or
2)
• FR-A842-07700(315K) or higher
Without regenerative function (FR-CC2)
Brake unit (FR-CC2+FR-BU2 (MT-BR5))
High power factor converter (FR-HC2)
*1 For the FR-A820-00490(7.5K) or lower and FR-A840-00250(7.5K) or lower.
*2 For the FR-A820-00630(11K) or higher, and FR-A840-00310(11K) or higher.
*3 The built-in brake is installed on FR-A820-00490(7.5K) or lower and FR-A840-00250(7.5K) or lower.
*4 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.
NOTE
• For the use of a brake resistor other than the FR-ABR, contact your sales representative.
 When using the built-in brake resistor or brake unit (FR-BU2, BU, FR-BU)
(FR-A820-03160(55K) or lower, FR-A840-01800(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". The Pr.70 setting is invalid. At this time, the regenerative brake duty
is as follows.
FR-A820-00250(3.7K) or lower
FR-A820-00340(5.5K), FR-A820-00490(7.5K)
FR-A840-00250(7.5K) or lower
Other than the above
NOTE
• The built-in brake resistor is equipped for the FR-A820-00490(7.5K) or lower, and the FR-A840-00250(7.5K) or lower.
 When using the high-duty brake resistor (FR-ABR) (FR-A820-01250(22K)
or lower, FR-A840-00620(22K) or lower)
• Set "1, 11, or 21" in Pr.30.
• Set Pr.70 as follows.
FR-A820-00490(7.5K) or lower, FR-A840-00250(7.5K) or lower
FR-A820-00630(11K) or higher, FR-A840-00310(11K) or higher
 When using the brake unit (FR-BU2) (FR-A820-03800(75K) or higher, FR-
A840-02160(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.
