The Schneider ATV9B0C40R4 is an Altivar Process ATV900 modular drive rated 400 kW at 440 V normal duty, 315 kW heavy duty. Line current hits 563 A at 440 V normal duty, 446 A heavy duty. The control supply architecture is split: external 24 V DC (19...30 V) for digital inputs, an internal 10.5 V DC reference for a 1 to 10 kOhm potentiometer, and a separate 24 V DC (21...27 V) rail for digital inputs and STO.
Duty and safety
Apparent power is 429 kVA at 440 V normal duty, 340 kVA heavy duty. The drive includes STO (safe torque off) rated SIL 3. Switching frequency is adjustable 2 to 8 kHz with derating above 2.5 kHz. Integrated EMC filter meets IEC 61800-3 category C3 for 300 m cable runs.
Fieldbus and I/O slots
Three option card slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, CANopen (RJ45, SUB-D 9, or screw terminals), EtherCAT, plus digital/analog I/O extension and output relay modules. Slot B also supports 5/12 V digital encoder, analog encoder, or resolver interface. Built-in Ethernet IP/Modbus TCP on two RJ45 ports; one separate RJ45 for Modbus serial (RTU, 2-wire RS485, 4.8 to 38.4 kbit/s).
