• FR-A820-03160(55K) or lower, FR-A840-01800(55K) or lower
• FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher
• FR-A842-07700(315K) or higher
 For the FR-A820-00490(7.5K) or lower and FR-A840-00250(7.5K) or lower.
 For the FR-A820-00630(11K) or higher, and FR-A840-00310(11K) or higher.
 Built-in brake is installed on FR-A820-00490(7.5K) or lower, FR-A840-00250(7.5K) or lower.
 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 FR-ABR, contact your sales representative.
When using built-in brake resistor, 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 FR-BU2 in combination with GZG/GRZG/FR-BR, or using BU or FR-BU, set Pr.30 = "0
(initial value), 10, 20, 100, 110, 120". Setting of Pr.70 will become disabled.
At this time, the regenerative brake duty is as follows.
• FR-A820-00250(3.7K) or lower................................3%
• FR-A820-00340(5.5K), FR-A820-00490(7.5K) ........ 2%
• FR-A840-00250(7.5K) or lower................................2%
• Other than above .....................................................0% (without built-in brake resistor)
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.
