It carries the SAFUR125F500 braking resistor paired with the NBRA-656C chopper at 4 Ohm (Rsel), which is what gives the drive a peak braking capacity of 113 kW (Ppeak) — the number that governs how hard the DC-link can absorb regenerated energy during a fast decel or an overhauling load. The output stage is built around an FOCH-0260-70 output choke rated 289 A thermal, with motor cable runs permitted up to 300 m whether the choke is fitted or not — so the EMC strategy and the motor-cable reach can be planned off the same ceiling. ## Braking loop and decel envelope Ppeak of 113 kW against a 9 kW continuous rating is the figure that tells you this drive was specified for high-inertia or overhauling loads where regenerated energy has to go somewhere fast — the SAFUR125F500 / NBRA-656C chain is sized for that peak, not for the running duty. Rsel of 4 Ohm is the resistor value the chopper is configured against; if the field retrofits a different resistor later, the chopper setpoint has to move with it, otherwise the brake current profile shifts and the thermal margin on the resistor changes. ## Sourcing posture Planners should allow the lead-time envelope of 6 to 10 weeks that the supply channel reports, with the SAFUR125F500 resistor and NBRA-656C chopper considered part of the same sourcing decision — splitting them across two orders risks a commissioning hold if one lands late.","metaTitle":"ABB ACS510-01-157A-4 drive, 157 A, 9 kW cont.","metaDescription":"ABB ACS510-01-157A-4 standard drive, 157 A I2N, 9 kW continuous / 113 kW peak, R6 frame, with SAFUR125F500 / NBRA-656C braking chain.
