The 3AXD50001109523: The drive carries three duty ratings: normal use at 1.5 kW / 4 A, heavy-duty at 1.1 kW / 3.3 A, and light-overload at 1.5 kW / 3.8 A. For UL-listed installs, the light-overload output is 2 Hp at 3.5 A. The 0.98 power factor and IE2 efficiency level keep line draw clean and losses low. Standby loss is 14 W — relevant if the drive idles for long periods in a pumping station. The 2 analog inputs and 2 analog outputs give you pressure or flow transducer feedback plus a speed reference or status signal. The 6 digital inputs and 3 digital outputs handle start/stop, fault reset, and run indication without an extra I/O block.
Enclosure, mounting, and environment
Rated IP66 and NEMA 4X, so it handles hose-down, dust, and corrosive atmospheres common in water treatment. Maximum ambient is 40 °C — derate if the pump room runs hotter. Wall-mounted, no floor stand needed. The lithium coin cell (CR2032, 220 mAh) keeps the real-time clock and parameter backup alive during power loss; it's user-replaceable.
