Drive selection note for the 3AXD50000050481
LV AC cabinet-built drive sized for a 500 kW normal-use induction motor at 880 A output on a 400 V three-phase supply. Heavy-duty use derates to 400 kW and 725 A; light-overload use holds the 500 kW but draws 865 A.
What the duty ratings mean for pump and fan loads
The normal-use (Pn) rating of 500 kW / 880 A is the curve for variable-torque loads — pumps and fans with quadratic torque-speed profiles. The 0.98 power factor reflects the active front-end or integrated filter; expect near-unity PF across the operating band. Sound level is 71 dB(A) — typical for an R11 frame at full load; plan for panel-door attenuation if the drive is in a quiet zone.
I/O and communication at a glance
Two analog inputs and two analog outputs are onboard. Digital I/O counts 6 inputs and 3 outputs. Communication is CAN-based; there are zero Industrial Ethernet interfaces on this variant. Ambient temperature limit is 40 °C maximum; operating humidity spans 5 to 95 % RH. The drive includes a CR2032 lithium coin cell for real-time clock backup — 220 mAh, 3 V, 1 piece, 3 g.
