Product details

The ATV950D45N4E variable speed drive from the Altivar Process ATV900 series is rated 45 kW for normal duty and 37 kW for heavy duty, with a continuous output current of 88 A at 4 kHz. The 88 A figure governs feeder cable sizing and thermal margin for sustained motor loads. The drive accepts 380-480 V three-phase and is IP55 enclosed for washdown or dusty environments.

Mounting and installation constraints

Mounts wall-vertical within ±10°. Terminal capacity on motor and line side is 35-50 mm² screw terminals. Expect current derating of 1% per 100 m above 1000 m altitude. Vibration resistance 1.5 mm at 2–13 Hz, 1 gn at 13–200 Hz. Shock resistance 15 gn for 11 ms.

Fieldbus and control interfaces

Embedded protocols include EtherNet/IP, Modbus TCP, and Modbus serial. Slot A accepts optional communication modules for Profibus DP, PROFINET, DeviceNet, EtherCAT, CANopen, or Ethernet Powerlink. Digital inputs accept 24 V DC supply (19–30 V external or 21–27 V internal for STO). Internal 10.5 V DC supply for external reference potentiometer (1–10 kOhm).

Frequently asked questions

What are the main electrical ratings for this drive?

It delivers 45 kW for normal duty, 37 kW for heavy duty, with a continuous output of 88 A at 4 kHz switching frequency, on 380-480 V three-phase supply.

Which communication protocols are built in?

EtherNet/IP, Modbus TCP, and Modbus serial are integrated. Additional protocol modules (Profibus, PROFINET, DeviceNet, etc.) can be added via slot A.

What safety and compliance standards does this drive meet?

It complies with UL 508C, IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and IEC 13849-1, among others.

What are the supply voltage options for the digital inputs?

Digital inputs can use an external 24 V DC supply (19–30 V) or the internal 24 V DC supply (21–27 V) which also powers STO. A separate 10.5 V DC supply is provided for an external reference potentiometer.
