The ATV950C11N4F is a 110 kW normal-duty / 90 kW heavy-duty variable speed drive from the Altivar Process ATV900 series, designed for industrial applications with synchronous or asynchronous motors. Rated supply voltage is 380...440 V three-phase, so it lands squarely on standard European and North American 400 V class industrial networks. The IP54 enclosure means it handles dust and splashing water — suitable for floor-standing installation in a panel or machine bay where occasional washdown or airborne particulates are a concern, but not for direct outdoor exposure or high-pressure spray.
Control wiring and supply architecture
Digital inputs need an external 24 V DC supply (19...30 V range). There is also an internal 24 V DC supply (21...27 V) for the digital inputs and the STO safety circuit, plus a separate 10.5 V DC reference supply for a 1 to 10 kOhm potentiometer. That means you can run the control logic from the drive's own supply for basic setups, but if you need isolated control or a longer cable run, plan on an external 24 V source. The control terminals are removable screw terminals accepting 0.5...1.5 mm² — standard for panel wiring. The drive ships with an integrated EMC filter (with an optional EMC plate), which simplifies compliance with IEC 61800-3 for conducted emissions in industrial environments. The built-in Modbus serial port and dual Ethernet ports (EtherNet/IP and Modbus TCP) handle most fieldbus integration out of the box, with option slots for Profibus DP, PROFINET, DeviceNet, EtherCAT, CANopen, and Ethernet Powerlink if your line requires a specific protocol.
What the standards tell you about fit
The drive is designed to IEC 61800-2 (adjustable speed drives), IEC 61800-3 (EMC), and IEC 61800-5-1 (safety), which covers the electrical safety and performance requirements for variable-speed drives in industrial environments. The CE marking confirms conformity for the European market.
