The ATV9B0C80T4 is a modular Altivar Process ATV900 drive sized for 1100 HP at 480 V normal duty, 900 HP at 480 V heavy duty. Line current runs 1049 A normal duty, 862 A heavy duty at 480 V; regenerative mode pulls 929.1 A normal duty, 756.3 A heavy duty. The internal supply rails are separate: 24 V DC (19…30 V) for digital inputs, 10.5 V DC ±5 % for a reference potentiometer (1 to 10 kΩ), and a dedicated 24 V DC (21…27 V) rail for digital inputs and STO.
Safety and compliance
The drive carries CE marking and complies with IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, UL 61800-5-1. Integrated EMC filter meets IEC 61800-3 category C3 for 300 m cable runs. Pollution degree 2 per IEC 61800-5-1.
Fieldbus and I/O expansion
Slot A accepts communication modules for Profibus DP V1, PROFINET, DeviceNet, CANopen (daisy chain RJ45, SUB-D 9, or screw terminals), and EtherCAT. Slot A/B/C accept digital/analog I/O extension modules and output relay extension modules. Slot B accepts 5/12 V digital encoder, analog encoder, and resolver encoder interface modules. Dual RJ45 ports for Ethernet IP/Modbus TCP; one RJ45 for Modbus serial. Modbus serial runs 2-wire RS-485 at 4.8, 9.6, 19.2, 38.4 kbit/s, RTU frame, 1…247 addresses.
