The ABB 3AXD50000707263 is an ACQ80-04-02kW2-4 low-voltage AC drive module purpose-built for solar pump applications. It delivers 2.2 kW output power at 5.6 A in normal (light-overload) use, and 1.5 kW at 4 A in heavy-duty use — the rating that governs continuous motor operation in hot, high-irradiance conditions. Input accepts 380-480 V three-phase, 47.5-63 Hz, so it handles both 50 Hz and 60 Hz grids without derating. The drive includes a control unit, mounts as a module (Frame R0), and is rated IP20 for clean indoor panel environments.
Normal-use output (2.2 kW / 5.6 A) matches the pump motor's nameplate for most solar tracking and booster applications. Heavy-duty output (1.5 kW / 4 A) is the rating to size against when ambient temperature hits 50 °C or the pump sees sustained overload — the drive's maximum ambient is 50 °C, so in a hot cabinet that heavy-duty number is the one that keeps the drive online. Standby loss is 15 W, power consumption at full load is 91 W — low enough that cabinet ventilation requirements are modest for a 2.2 kW class drive.
The drive provides 2 analog inputs, 2 analog outputs, 6 digital inputs, and 3 digital outputs — enough for pressure transducer feedback, start/stop from a PLC or float switch, and a run-status relay. Communication is CAN-based, not Ethernet; if the site uses Modbus TCP or PROFINET, a separate gateway or option module is needed. The lithium coin cell (CR2032, 220 mAh) keeps real-time clock and parameter backup alive during power loss.
