Power and duty ratings for motor control
The ATV930D15N4: Rated 15.0 kW normal duty and 11.0 kW heavy duty at 380...480 V 3-phase input, with a nominal output current of 31.7 A (normal duty at 4 kHz) and 23.5 A (heavy duty at 4 kHz).
Fieldbus and I/O expansion options
Three option slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (daisy chain RJ45 or SUB-D 9 or screw terminals), and Ethernet Powerlink, plus digital/analog I/O extension and encoder interface modules (5/12 V digital, analog, resolver). The base unit includes Modbus serial, Modbus TCP, and EtherNet/IP ports with auto-negotiation at 10/100 Mbits.
Built-in braking chopper for deceleration control
Standard version includes a braking chopper — no external chopper module needed for dynamic braking. On fast stops or overhauling loads (cranes, centrifuges), the chopper dumps regenerated energy into an external resistor, preventing DC-bus overvoltage trips. The DC bus screw terminals (10...16 mm²) are sized for the resistor connection.
