Load profiles and thermal margin
The 3AXD50000115297: Three duty ratings are defined: light-overload at 315 kW / 320 A, normal-use at 315 kW / 330 A, and heavy-duty at 250 kW / 271 A. Ambient temperature tops out at +55 °C, and the drive is rated for installation up to 4000 m altitude without derating — a useful margin for high-altitude sites. Standby loss is 214 W; full-load power consumption is 5485 W at the listed apparent power of 394 kV·A.
The control unit includes 2 analog inputs, 2 analog outputs, 6 digital inputs, and 2 digital outputs. Communication is via CAN; there is no onboard Industrial Ethernet interface. The unit ships with a lithium coin cell (CR2032, 220 mAh) for real-time-clock backup — two cells are fitted, total 6 g.
