It delivers 12.7 A continuous output at 4 kHz for normal duty, and 9.3 A at 4 kHz for heavy duty. The IP55 enclosure with integrated EMC filter and braking chopper makes it suited for standalone installation in process environments where dust and hose-down are present. For heavy-duty cycles (e.g., extruders or crushers with higher starting torque), the drive derates to 9.3 A at the same switching frequency. IP55 means the drive withstands water jets and dust ingress — suitable for washdown areas in food-and-bev or chemical processing without a separate cabinet. The drive carries CE marking and complies with UL 508C, IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonic limits), IEC 60721-3 (environmental), IEC 61508, and IEC 13849-1 (functional safety). Integrated EMC filter meets conducted emission limits for industrial environments without an external filter in most installations. ## Integration notes Wall-mount enclosed assembly with screw terminals for line, motor, DC bus, and control wiring. Control terminals accept 0.5...1.5 mm²; power terminals accept 4...6 mm². Three option slots (A, B, C) accept communication modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, Ethernet Powerlink, plus digital/analog I/O and relay extension modules. Slot B also accepts encoder interface modules (digital 5/12 V, analog, resolver). Communication ports include EtherNet/IP, Modbus TCP, and Modbus serial. The integrated braking chopper handles dynamic braking without an external module for applications requiring rapid deceleration or overhauling loads.","metaTitle":"ATV950U55N4 Altivar Process ATV900 VSD, 5.5 kW ND, IP55","metaDescription":"ATV950U55N4 variable speed drive, 5.5 kW normal duty / 4.0 kW heavy duty, 380-480 V 3-phase, IP55, integrated EMC filter, braking chopper, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Supply":"External supply for digital inputs: 24 V DC (19...30 V), Internal supply for reference potentiometer (1 to 10 kOhm): 10.5 V DC +/- 5 %, Internal supply for digital inputs and STO: 24 V DC (21...27 V), 1 MOhm 500 V DC for 1 minute to earth","Marking":"CE","Variant":"With braking chopper Standard version","Standards":"UL 508C IEC 61800-3 IEC 61800-5-1 IEC 61000-3-12 IEC 60721-3 IEC 61508 IEC 13849-1","EMC filter":"Integrated With EMC plate option","Data format":"8 bits, configurable odd, even or no parity","Noise level":"52 dB","Maximum THDI":"<48 % full load conforming to IEC 61000-3-12","Exchange mode":"Half duplex, full duplex, autonegotiation Ethernet IP/Modbus TCP","Mounting mode":"Wall mount","Option Module":"Slot A: communication module for Profibus DP V1 Slot A: communication module for PROFINET Slot A: communication module for DeviceNet Slot A: communication module for EtherCAT Slot A: communication module for CANopen daisy chain RJ45 Slot A: communication module for CANopen SUB-D 9 Slot A: communication module for CANopen screw terminals Slot A/slot B/slot C: digital and analog I/O extension module Slot A/slot B/slot C: output relay extension module Slot B: 5/12 V digital encoder interface module Slot B: analog encoder interface module Slot B: resolver encoder interface module communication module for Ethernet Powerlink","Assembly style":"Enclosed","Motor power kW":"5.5 kW for normal duty 4.0 kW for heavy duty","Regulation loop":"Adjustable PID regulator","lifecycle_stage":"current","Pollution degree":"2","Range of product":"Altivar Process ATV900","Shock resistance":"15 gn for 11 ms conforming to IEC 60068-2-27","Relative humidity":"5...95 % without condensation conforming to IEC 60068-2-3","Transmission rate":"10, 100 Mbits 4.8 kbps 9600 bit/s 19200 bit/s","Device application":"Industrial application","Operating altitude":"1000...4800 m with current derating 1 % per 100 m","Operating position":"Vertical +/- 10 degree","Number of addresses":"1...247","Product destination":"Synchronous motors Asynchronous motors","Degree of protection":"UL type 1","Overvoltage category":"III","Type of polarization":"No impedance","Vibration resistance":"1.5 mm peak to peak (f= 2...13 Hz) conforming to IEC 60068-2-6 1 gn (f= 13...200 Hz) conforming to IEC 60068-2-6","Electrical connection":"Control: screw terminal 0.5...1.5 mm²/AWG 20...AWG 16 DC bus: screw terminal 2.5...6 mm²/AWG 14...AWG 10 Motor: screw terminal 4...6 mm²/AWG 12...AWG 10 Line side: screw terminal 4...6 mm²/AWG 12...AWG 10","Nominal Output Current":"12.7 A","IP degree of protection":"IP55","Network number of phases":"3 phases","Continuous output current":"12.7 A at 4 kHz for normal duty 9.3 A at 4 kHz for heavy duty","Product or component type":"Variable speed drive","[Us] rated supply voltage":"380...480 V","Communication port protocol":"EtherNet/IP Modbus TCP Modbus serial","Environmental characteristic":"Chemical pollution resistance class 3C3 conforming to IEC 60721-3-3 Dust pollution resistance class 3S3 conforming to IEC 60721-3-3","Product specific application":"Process for industrial","Electromagnetic compatibility":"Electrostatic discharge immunity test level 3 conforming to IEC 61000-4-2 Radiated radio-frequency electromagnetic field immunity test level 3 conforming to IEC 61000-4-3 Electrical fast transient/burst immunity test level 4 conforming to IEC 61000-4-4 1.2/50 µs -
