Braking chopper and resistor stack
The ACS510-01-290A-4: Braking is handled by the NBRA-658C chopper paired with a 2xSAFUR210F575 resistor stack, which is the R-type combination shipped with this build; the resistor set is selected at 1.7 Ω to match the chopper rating for the 229 kW peak dissipation window.
Output filtering and cable runs
The drive pairs with an FOCH-0320-50 output choke rated at 445 A thermal current, with a 300 m maximum motor cable length both with and without the choke installed — meaning the EMC ceiling is set by the choke choice rather than by cable distance on this build.
