Power stage and duty-cycle rating
The ATV9B0C31N6: The line current at 500 V normal duty is 278 A; heavy duty drops to 204 A, and regenerative modes carry their own lower figures (231 A normal, 167 A heavy). Apparent power follows the same pattern: 241 kVA normal duty, 176 kVA heavy duty, with regenerative-mode ratings at 200 kVA and 145 kVA respectively. The 50 kA prospective line Isc rating means the input circuit must coordinate with upstream protection capable of interrupting that fault level.
Safety, compliance, and fieldbus integration
The integrated EMC filter handles 300 m cable runs at Category C3 per IEC 61800-3, which covers second-environment industrial installations. Three option-card slots (Slot A, B, C) accept fieldbus modules for Profibus DP V1, PROFINET, DeviceNet, CANopen, or EtherCAT, plus digital/analog I/O and output relay expansion. The native Modbus serial port (2-wire RS-485, RTU) and dual RJ45 Ethernet IP/Modbus TCP ports are on the terminal block — no extra card needed for basic Ethernet comms.
