What it is
Mass is 15.42 kg on the spec row, which is the figure that decides whether two people can wrestle it onto a backplate or whether a single technician needs a lift. For an ACS800-01-0050-3 that's going into a retrofit panel next to existing ABB drives, that handling note is more useful than any number off the rating plate. The category trail — Motors & Motor Controls → Drives → Motor Drives — is how this drive is filed, and it tells you what kind of BOM line it answers: a low-voltage industrial AC drive for a single motor on a three-phase bus.
Application fit — constant vs. variable torque, cable, harmonics
The order code ACS800-01-0050-3 identifies a specific rating slot on the ACS800-01 wall-mount platform. The retrofit question is the load profile — constant-torque versus quadratic-torque — because that is what sets the parameter set and the brake-chopper resistor. If the cable run pushes past the documented maximum, plan a dV/dt or sinus filter on the output. For panel integration, treat the ACS800-01-0050-3 as a closed device: power terminals land on the input contactor/breaker side, motor terminals on the output, and the control terminals take the start/stop, reference, and any fieldbus option. Confirm the fieldbus option card slot is populated to match the PLC side (Profibus, Modbus, DeviceNet, or Ethernet — the platform takes the same option cards as other ACS800-01 drives). If the line has been migrated to ACS880 control, expect a firmware and option-card gap, not a terminal-strip gap.
Cross-reference: ACS800-01-0050-3 vs. the ACS880-01 line
The ACS880-01 series — listed here as ACS880-01-040A-5 (18.14 kg), ACS880-01-034A-5 (10.43 kg), and ACS880-01-027A-5 (10.41 kg) — sits in the same Motor Drives line. Treat the ACS880-01 candidates as second-source substitutes only after verifying current rating, voltage class, frame depth, and fieldbus option card compatibility against the existing BOM line — not as an automatic swap.
