The heavy-duty rating governs continuous overload capability for pumps, conveyors, or compressors that see sustained torque; the normal-duty figure applies when the load profile stays below the drive's rated current most of the cycle. ## Safety and compliance backbone The drive also carries CE marking and complies with IEC 61800-3 (EMC), IEC 61800-5-1 (safety), UL 61800-5-1, and IEC 61000-3-12 for harmonic emissions. ## Fieldbus and I/O expansion slots Three option slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, CANopen, EtherCAT, or Ethernet IP/Modbus TCP — the base unit already carries two RJ45 Ethernet ports and one RJ45 Modbus serial port. Slot A/B/C also accept digital/analog I/O extension and output relay modules, so the drive can absorb remote I/O without a separate fieldbus coupler. ## Switching frequency and derating Adjustable carrier from 2 to 8 kHz; the 2.5–8 kHz range carries a derating factor. Running at 8 kHz quiets motor whine but reduces continuous output current — budget the derating into the cable and heatsink sizing if the application demands low audible noise.","metaTitle":"Schneider Electric ATV9B0C20T4 Altivar Process 900, 300 HP","metaDescription":"Schneider Electric ATV9B0C20T4 Altivar Process ATV900 AC drive, 300 HP at 480 V normal duty, 250 HP heavy duty.
