The ATV9A0C31T4 is an active-production Altivar Process ATV900 modular drive rated for 500 hp at 480 V normal duty and 400 hp at 480 V heavy duty, with corresponding line currents of 528 A and 427 A. It drives both asynchronous and synchronous motors and includes an integrated EMC filter compliant with IEC 61800-3 category C3 for cable runs up to 300 m. Control power comes from a 24 V DC external supply for digital inputs (19...30 V) and a separate 24 V DC internal supply for digital inputs and STO (21...27 V). A 10.5 V DC reference supply is available for a 1 to 10 kOhm potentiometer.
Fieldbus and safety integration
The drive ships with dual RJ45 ports for Ethernet IP/Modbus TCP on the control block and one RJ45 for Modbus serial. Slot A accepts communication option cards for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, or CANopen (RJ45, SUB-D 9, or screw terminals). Slots A, B, and C support digital/analog I/O extension and relay output modules; slot B also accepts encoder interface modules (5/12 V digital, analog, or resolver).
