ABB ACS580-01 - Resistor Braking, Frames R4; Planning the Braking System

230 Resistor braking
Resistor braking, frames R4…R9
 Planning the braking system
Frames R4…R9 need external brake choppers and resistors. The table below lists
suitable choppers and resistors.
For more information, see NBRA-6xx Braking Choppers Installation and start-up
guide (3AFY58920541 [English]) and ACS-BRK Brake Units Installation and start-up
guide (3AFY61514309 [English]).
