The 3AXD50000043928: The 25 A normal-use current (In) is the headline number for a standard variable-torque pump/fan application. For a constant-torque or high-starting-duty load, use the 17 A heavy-duty figure (IhD) — that is the rating that governs the real-world thermal limit. The 7.5 kW heavy-duty power (PhD) tells you the motor size this drive can handle continuously under full torque. Input voltage range is 380–415 V, so it fits standard 400 V three-phase grids. Frequency tolerance is 47.5–63 Hz, covering both 50 Hz and 60 Hz systems. The drive is IE2 efficiency class, which is the baseline for regenerative units; note the ecodesign exemption for regenerative drives means no energy-efficiency data is required under EU 2019/1781.
Integration notes
The drive has 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 2 digital outputs. Communication is via CAN — there is no onboard industrial Ethernet interface. The control unit is included. Standby loss is 39 W; power consumption at full load is 822 W. Apparent power output is 17 kVA. The drive is rated for installation at altitudes up to 4000 m (derating applies above 1000 m per standard practice). Operating temperature range goes to +55 °C, humidity 5–95% non-condensing. Sound level is 57 dB(A). The internal battery is a CR2032 lithium coin cell, 220 mAh, 3 V, two pieces. The WEEE category is 5 (small equipment).
