600 hp at 480 V — normal and heavy duty profiles
The ATV9B0C40T4 is a modular Altivar Process ATV900 drive rated 600 hp at 480 V in normal duty and 500 hp at 480 V in heavy duty, with corresponding line currents of 578 A and 484 A. The heavy-duty profile gives you headroom for constant-torque loads like conveyors or extruders where the motor draws full current across the speed range.
Built-in safety and EMC compliance
The drive also carries an integrated EMC filter rated for 300 m cable runs to IEC 61800-3 category C3, which covers most industrial installations without an add-on filter. Total harmonic current distortion (THDI) is below 5 % at full load per IEEE 519, so it won't cause nuisance tripping on shared distribution transformers.
Fieldbus and I/O expansion
The drive ships with dual RJ45 Ethernet IP/Modbus TCP ports and one RJ45 Modbus serial port. For Profibus DP, PROFINET, EtherCAT, DeviceNet, or CANopen, the three option-card slots (A, B, C) accept the corresponding communication modules. Slot B also accepts encoder interface modules (digital 5/12 V, analog, or resolver).
Switching frequency and derating
Switching frequency is adjustable from 2 to 8 kHz, with a derating factor applied above 2.5 kHz. Running at 8 kHz quiets motor whine but reduces continuous output current — budget the derating into the drive sizing if the application is noise-sensitive.
