The Schneider ATV9A0C71Q4 is an Altivar Process ATV900 modular drive rated for 710 kW at 400 V normal duty and 560 kW at 400 V heavy duty, with a corresponding line current of 1192 A normal duty and 951 A heavy duty. It drives both asynchronous and synchronous motors, with an integrated EMC filter rated for 300 m cable run per IEC 61800-3 Category C3.
Control supply and fieldbus
Control power comes from two separate 24 V DC rails: one for digital inputs (19...30 V) and one for digital inputs and STO (21...27 V). An internal 10.5 V DC supply powers a 1 to 10 kOhm reference potentiometer. The drive ships with dual RJ45 ports for Ethernet IP/Modbus TCP at 10/100 Mbit/s and one RJ45 for Modbus serial (RTU, 2-wire RS485, 4.8 to 38.4 kbit/s). Three option slots (A, B, C) accept fieldbus modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, plus digital/analog I/O or relay extensions.
Cabinet-mount design, IP00 rated for integration into IP21 or IP54 enclosures. Forced convection cooling. Operating altitude up to 4800 m with current derating above 1000 m. Ambient humidity 5...95 % non-condensing. Switching frequency adjustable 2...8 kHz with derating factor. Prospective line Isc rated at 50 kA.
