Drive specifications and motor ratings
The ATV9A0C25T6 is a modular Altivar Process ATV900 drive rated for 250 hp at 600 V normal duty and 200 hp at 600 V heavy duty, drawing 218 A and 179 A line current respectively. Apparent power is 227 kVA (normal) / 186 kVA (heavy) at 600 V. Prospective line Isc is 50 kA, which sets the SCCR requirement for upstream protection. The drive supports both synchronous and asynchronous motors, with adjustable switching frequency from 2 kHz to 4.9 kHz (derated). Forced convection cooling keeps it within a 0-2000 m altitude envelope, derating above 1000 m. The integrated EMC filter meets IEC 61800-3 category C3 for 300 m cable runs, suitable for industrial installations with isolated neutral or IT mains.
Control supplies, communication, and safety
Drive control logic requires an external 24 V DC supply (19...30 V) for digital inputs, plus a separate 24 V DC supply (21...27 V) for STO and internal digital input power. An internal 10.5 V DC reference supply is provided for a 1-10 kΩ potentiometer. Communication options are extensive: slot A accepts module cards for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (RJ45, SUB-D 9, or screw terminal), and Ethernet IP/Modbus TCP. Slots A/B/C can host digital/analog I/O or relay expansion modules. Slot B accepts encoder interface modules (digital 5/12 V, analog, or resolver). The drive comes with a built-in Modbus serial port (2-wire RS 485, RTU, 1-247 addresses, configurable parity). Ethernet IP/Modbus TCP interface supports half/full duplex and 10/100 Mbit/s. No Modbus bridge inside—fieldbus protocol is determined by the option card in slot A. The drive also provides extensive protective functions: thermal protection for motor and drive, motor phase break, overcurrent, overspeed, line supply undervoltage/phase loss, and earth fault protection.
Standards, compliance, and sourcing
This drive is CE-marked and complies with IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, IEC 13849-1, and UL 61800-5-1. It carries IP00 protection as standard, intended for IP21 or IP54 cabinet integration UL Type 1 or Type 12 when mounted in an enclosure. The modular kit includes a control unit, mechanical mounting kit, power connection set, set of fuses, 200 kW power module, and front cover. All terminal connections are screw-type (control: 0.5-1.5 mm²; line and motor: M10 bars).
