The ABB ACS510-01-246A-4 is a standard drive from the ACS510 line, populated as the R6 frame and rated 245 A nominal (I2N) for 13.5 kW continuous (Prated) operation. On the braking side, the drive ships with the NBRA-658C chopper matched to a SAFUR200F500 braking resistor, with a Ppeak of 198 kW and an Rsel of 2.7 Ohm — the resistor selection is the one that limits peak braking energy in this stack.
Braking envelope and resistor selection
Peak braking on this build is 198 kW (Ppeak) into a 2.7 Ohm resistor selection, which is the figure that defines how much regen energy the chopper can sink on a fast stop or a vertical-axis load — not the continuous kW rating. The continuous power figure of 13.5 kW is the motor-shaft rating, not the resistor dissipation figure; the SAFUR resistor is sized for short, high-peak duty and the chopper handles the gating.
Output choke and motor cable reach
The FOCH-0260-70 output choke is rated at 289 A thermal current, giving headroom over the 245 A drive nominal when the motor cable run is long. Maximum motor cable length is 300 m with the choke and 300 m without it — for an R6 frame at this current that is a generous figure, but bear in mind the choke is what keeps the dV/dt at the motor terminals inside the insulation limit on those longer runs.
