150 hp at 480 V with dual duty ratings
The ATV9A0C11T4 is a modular Altivar Process ATV900 drive rated 150 hp at 480 V normal duty and 125 hp at 480 V heavy duty, with corresponding line currents of 168 A and 145 A. Apparent power is 140 kVA normal duty, 121 kVA heavy duty.
STO SIL 3 and integrated EMC filter
The integrated EMC filter meets IEC 61800-3 category C3 for 300 m cable runs, which covers most industrial motor cable lengths without an add-on filter. The drive supports both synchronous and asynchronous motors, and the switching frequency is adjustable from 2 to 8 kHz with derating above 2.5 kHz — raising it quiets motor whine but reduces continuous output current.
Communication slots and control supply
Three option slots (A, B, C) accept fieldbus modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (RJ45, SUB-D 9, or screw terminals), plus digital/analog I/O and relay extension modules. Slot B also accepts encoder interface modules (digital 5/12 V, analog, resolver). The control block has dual RJ45 for Ethernet IP/Modbus TCP and one RJ45 for Modbus serial. Digital inputs need an external 24 V DC supply (19...30 V); the drive provides a 10.5 V DC reference for a potentiometer and a separate 24 V DC supply for digital inputs and STO.
Active production, quoted to order
The drive carries CE marking and complies with IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonics), IEC 60721-3 (environmental), IEC 61508, and IEC 13849-1 (functional safety). Prospective line short-circuit current rating is 50 kA.
