The 3AXD50000035920: The normal-use rating (22 kW, 50 A) is the continuous duty point for typical fan or pump loads. The heavy-duty rating (18.5 kW, 43 A) applies for constant-torque loads like conveyors or extruders, where the drive must deliver rated torque across the speed range. The light-overload rating matches the normal-use current (50 A) at 22 kW, indicating that the drive can handle occasional overloads up to that level without derating the output. Ambient temperature is limited to 40 °C maximum; above that, derate per the thermal curve in the manual. The IP21 enclosure and NEMA Type 1 rating suit indoor, clean environments — not washdown or outdoor locations.
The drive provides 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 2 digital outputs. Communication is via CAN protocol; there is no onboard industrial Ethernet interface. The control unit handles the I/O mapping and fieldbus interface; for Ethernet connectivity, an optional fieldbus adapter module is required.
