Duty ratings and real-world fit
The 3AXD50000956678: For heavy-duty use the drive is rated 2.2 kW at 9.3 A, and for light-overload use it holds 3.0 kW at 11.6 A. The UL listing mirrors these: 3.0 Hp normal-use, 3.0 Hp heavy-duty, and 3.0 Hp light-overload, with corresponding currents of 12.2 A, 9.8 A, and 11.6 A. That means the drive handles a 3.0 kW fan or pump continuously, and can sustain a 2.2 kW constant-torque load without derating.
Communications and I/O
BACnet is the onboard protocol, with 2 analog inputs and 1 analog output for sensor feedback, plus 4 digital inputs and 2 digital outputs for discrete control. No industrial Ethernet interface is built in — the drive relies on BACnet MS/TP or similar serial for BMS integration. The 47.5…63 Hz frequency range covers 50/60 Hz mains without adjustment.
