Resistor braking (D)

Brake choppers (D150)

The option contains brake chopper(s) for feeding braking energy to brake resistors
to be dissipated there.
The customer must connect brake resistors to the drive.
ACS800-07/U7 frames R5 to R8: The brake choppers are located inside the drive
module.
Standard option for ACS800-07 frame 2×R8i and ACS800-37 frames up to 2×R8i.
The brake choppers are located in their own cubicles. The number of the choppers
depends on the drive size. The choppers are of type NBRA.
ACS800-07 and ACS800-37 frames 3×R8i and above: Application-engineered
option
Not available for ACS800-17.

and Start-up Guide (3AFY58920541 [English])

Brake resistors (D151)

The option contains brake resistors. The number of the brake resistors depends on
the drive size. The resistors are of type SAFUR.
