It supports CANopen and Modbus protocols via an RJ45 connector, includes an integrated Class C2 EMC filter, and is rated IP20 for cabinet mounting. ## Applications As an Altivar 32 drive, it provides variable-speed control for three-phase asynchronous motors in applications such as conveyors, pumps, fans, and packaging machinery. The drive communicates via CANopen and Modbus, enabling integration into distributed automation networks without additional gateways. An adjustable PID regulator allows closed-loop process control for pressure, flow, or level regulation directly from the drive. Built-in protections include input phase loss, output phase-to-earth overcurrent, overheating, motor short-circuit, and thermal overload, reducing the need for external motor protection relays.","metaTitle":"Schneider ATV32H055N4437 Altivar 32 VFD, 550 W, 500 V, CANopen/Modbus","metaDescription":"Schneider Altivar 32 ATV32H055N4437 variable speed drive: 550 W, 500 V, 1.9 A output, CANopen/Modbus, IP20, integrated C2 EMC filter.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Depth":"245 mm","Width":"45 mm","Height":"325 mm","Supply":"Internal supply for reference potentiometer (1 to 10 kOhm): 10.5 V DC +/- 5 %, <10 mA, protection type: overload and short-circuit protection","Marking":"CE","Accuracy":"+/- 0.2 % (AI1, AI2, AI3) for a temperature of -10...60 °C +/- 0.5 % (AI1, AI2, AI3) for a temperature of 25 °C +/- 1 % (AO1) for a temperature of 25 °C +/- 2 % (AO1) for a temperature of -10...60 °C","Standards":"EN 55011 class A group 1 EN 61800-3 environments 1 category C2 EN 61800-3 environments 2 category C2 EN/IEC 61800-3 EN/IEC 61800-5-1","EMC filter":"Class C2 EMC filter integrated","Insulation":"Electrical between power and control","Noise level":"43 dB conforming to 86/188/EEC","Option card":"Communication card for CANopen daisy chain Communication card for CANopen open style Communication card for DeviceNet Communication card for EtherNet/IP Communication card for Profibus DP V1","Speed range":"1...100 for asynchronous motor in open-loop mode","Line current":"2.2 A for 500 V 3 phases 0.55 kW / 0.75 hp 2.8 A for 380 V 3 phases 0.55 kW / 0.75 hp","Functionality":"Mid","Response time":"LI1...LI6 8 ms, tolerance +/- 0.7 ms for logic output(s) R1A, R1B, R1C 2 ms for relay output(s) R2A, R2C 2 ms for relay output(s)","Apparent power":"1.9 kVA at 500 V 3 phases 0.55 kW / 0.75 hp","Assembly style":"With heat sink","Braking torque":"<= 170 % with braking resistor","Component name":"ATV32","Connector type":"1 RJ45 (on front face) for Modbus/CANopen","Motor power hp":"0.75 hp at 380...480 V","Motor power kW":"0.55 kW at 380...480 V","Output voltage":"<= power supply voltage","Speed accuracy":"+/- 10 % of nominal slip 0.2 Tn to Tn","Linearity error":"+/- 0.2...0.5 % of maximum value (AI1, AI2, AI3) +/- 0.3 % (AO1)","Protection type":"Input phase breaks: drive Overcurrent between output phases and earth: drive Overheating protection: drive Short-circuit between motor phases: drive Thermal protection: drive","Regulation loop":"Adjustable PID regulator","Torque accuracy":"+/- 15 %","lifecycle_stage":"current","Local signalling":"1 LED red for drive voltage 1 LED blue for bluetooth 1 LED green for CANopen run 1 LED red for CANopen error 1 LED red for drive fault","Method of access":"Slave CANopen","Output frequency":"0.0005...0.599 kHz","Pollution degree":"2 conforming to EN/IEC 61800-5-1","Range of product":"Altivar 32","Shock resistance":"15 gn for 11 ms conforming to EN/IEC 60068-2-27","Supply frequency":"50...60 Hz -
