The ATV9B0C71R4 is a modular cabinet-mount drive from the Altivar Process ATV900 family, rated for 710 kW at 440 V normal duty (560 kW heavy duty) with a corresponding line current of 995 A normal duty (789 A heavy duty). It supports both synchronous and asynchronous motors, and the switching frequency is adjustable from 2.5 to 8 kHz with derating.
Control supply and safety
Control wiring requires an external 24 V DC supply (19...30 V) for digital inputs, and an internal 24 V DC supply (21...27 V) powers the STO (safe torque off) circuit, which is certified to SIL 3. The drive also provides a 10.5 V DC ±5 % reference for a 1 to 10 kΩ potentiometer. Insulation resistance is 1 MΩ at 500 V DC for 1 minute to earth.
Fieldbus and option slots
Native communication includes dual RJ45 for Ethernet IP/Modbus TCP (10/100 Mbit/s) and one RJ45 for Modbus serial (4.8 to 38.4 kbit/s, RTU, 2-wire RS-485). Three option slots (A, B, C) accept fieldbus modules for Profibus DP V1, PROFINET, DeviceNet, CANopen, EtherCAT, as well as digital/analog I/O or relay extension modules. Slot B also supports encoder or resolver interface modules.
Cabinet mount, IP00 (requires IP21 or IP54 enclosure). Forced convection cooling. Operating altitude 0 to 4800 m with derating above 1000 m. Ambient humidity 5 to 95 % non-condensing. Shock resistance 4 gn for 11 ms; vibration resistance 1.5 mm peak-to-peak at 2-13 Hz and 0.5 gn at 13-200 Hz. Noise level 78 dB.
