The ATV6A0C20T4: The 200 kW normal-duty rating covers most 300 hp induction motors at 480 V; the heavy-duty 160 kW figure is the one to use for constant-torque loads like conveyors or extruders. The integrated EMC filter meets IEC 61800-3 category C3 for 300 m shielded cable, which saves adding an external filter for most industrial installations. Safe torque off (STO) is rated SIL 3 per IEC 61508, so you can wire the STOA/STOB inputs directly to a safety PLC or light curtain without a separate safety relay.
Integration notes
Cabinet-mount forced-convection cooling. The control unit accepts a communication module in Slot A — Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, or CANopen variants — and digital/analog I/O or relay extension modules in Slot A or B. The embedded Modbus serial port runs at 4.8 to 38.4 kbit/s, RTU frame; the Ethernet port handles Modbus TCP at 10/100 Mbit/s with half/full duplex and autonegotiation. Six discrete inputs (DI1–DI4 sampled at 2 ms, DI5–DI6 at 5 ms) plus three analog inputs (12-bit, voltage or current configurable) cover most process signals without an expansion card.
