Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Schneider Electric ATS480C17Y is an Altivar ATS480 series soft starter designed for controlled starting, torque management, and controlled deceleration of 3-phase asynchronous motors. Operating with a rated current of 170 A across main line supply voltages from 208 V AC to 690 V AC, this motor controller supports motor power outputs up to 45 kW at 230 V AC, 90 kW at 400 V AC, 110 kW at 500 V AC, and 160 kW at 690 V AC. Control logic is powered by an auxiliary supply input of 110 V AC to 230 V AC. Engineered as the modern successor to legacy Altivar ATS48 units, it maintains physical footprint alignment for straightforward mechanical retrofits in industrial equipment such as centrifugal pumps, ventilation fans, screw compressors, and conveyor systems.
Integrating the ATS480C17Y into an existing panel relies on matching both its network interfaces and control terminal wiring. The unit features dual embedded RJ45 10/100 Mbps switched Ethernet ports supporting Modbus TCP and EtherNet/IP with embedded web server diagnostics, alongside an RS-485 Modbus RTU serial line. System connectivity can be expanded using optional fieldbus modules for PROFINET (VW3A3627), PROFIBUS-DP (VW3A3607), or CANopen (VW3A3608/18/28). Physical terminal resources include four programmable 24V DC digital inputs, one dedicated STOP/RUN input, three relay outputs (R1, R2, R3), and one configurable analog input and output (0-10 V, 0-20 mA, 4-20 mA). Commissioning and parameter transfers are handled via Schneider Electric SoMove software, EcoStruxure PLC suites, or the optional VW3A1111 graphic display terminal. ABC Industrial Parts can support maintenance teams requiring tested replacement starters or parameter extraction from existing field hardware.
Operational monitoring and fault identification are supported on-device and through network protocols. Integrated status LEDs report motor execution state, network activity, and detected fault conditions, while specific error codes are displayed on the front terminal or accessible via web diagnostic interfaces. Basic field checks for external trips include verifying line supply stability, motor thermal settings, phase continuity, and digital input circuits. However, internal hardware errors such as microcontroller or power board circuit failures cannot be serviced in the field; if a red fault condition remains active following a complete power cycle, replacing the soft starter or arranging unit repair through ABC Industrial Parts provides the safest path to restore operation.

Programming and Configuration
Parameter setup and commissioning for the Schneider Electric ATS480C17Y soft starter are supported using Schneider Electric SoMove software, EcoStruxure Control Expert, or EcoStruxure Machine Expert PLC engineering suites. All configuration parameters, ramp profile settings, and motor protection curves are stored in non-volatile flash memory to retain drive data through complete power interruptions. Local configuration can also be performed via the optional VW3A1111 graphic display terminal or using web browser diagnostic pages provided by the internal web server.
For maintenance operations replacing an installed Altivar ATS48 unit, the ATS480 platform offers parameter migration compatibility. Parameter backup files from ATS48 units can be imported, adjusted, and uploaded through SoMove software to streamline setup. Prior to placing a replacement soft starter into active control, technicians should verify motor thermal current limits, start/stop ramp times, and digital assignment functions to ensure correct system behavior under load.
Communication and System Integration
The ATS480C17Y includes dual switched RJ45 Ethernet ports operating at 10/100 Mbps, enabling daisy-chain topologies without external industrial switches. Built-in network capabilities feature Modbus TCP and EtherNet/IP protocols alongside an embedded web server for real-time monitoring and parameter status access. Cybersecurity architecture complies with the IEC 62443 standard to prevent unauthorized system modifications across connected network infrastructures.
Serial automation links are provided via an RJ45 RS-485 interface operating Modbus RTU at baud rates up to 115.2 kbps. For integration into alternative fieldbus environments, optional communication modules can be installed into the starter slot, including VW3A3627 for PROFINET, VW3A3607 for PROFIBUS-DP, and VW3A3608, VW3A3618, or VW3A3628 for CANopen networks.
Diagnostics and Status Indication
System diagnostic visibility is provided through status LEDs, front keypad error codes, web browser pages, and fieldbus diagnostic registers. Real-time parameters such as operating state, fault logs, and input/output statuses can be continuously monitored within the SoMove commissioning environment or through PLC master diagnostic reads.
Front-panel LED indicators give direct visual feedback on the operational state. The RUN indicator signals motor state during starting, acceleration, bypass, and deceleration phases. The NET / COMM indicator shows fieldbus and Ethernet communication link status. Detected faults activate the red FAULT / ERROR LED, triggering a corresponding error code on the display terminal or fieldbus network.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RUN | Variable | Indicates motor operation status (starting, acceleration, bypass, deceleration) |
| FAULT / ERROR | Red - Solid or Flashing | Indicates detected error or fault condition. A persistent red fault state upon power cycle signals an internal hardware failure requiring repair or replacement |
| NET / COMM | Variable | Indicates status of fieldbus and Ethernet communication connection and activity |
Replacement and Spare Part Considerations
The ATS480C17Y serves as the direct upgrade and replacement path for legacy Altivar ATS48 soft starters. It uses an identical mounting footprint to equivalent ATS48 models, allowing engineers to replace faulty units in control cabinets without modifying panel cutouts, backplate drilling, or power busbar structures.
Before applying power to a replacement soft starter, ensure that main supply voltage (208 to 690 V AC) and control supply (110 to 230 V AC) line connections match system specifications. Uploading a verified parameter configuration file using SoMove software ensures correct setup of motor rated current, acceleration times, and digital input control mappings.
