Product Overview
The Schneider ATS480D32Y Soft Starter is an industrial motor-control solution from the Altivar Soft Starter ATS480 family, designed for controlled starting and stopping of three-phase asynchronous motors. The model is rated at 32 A and is designed for motor applications across a broad 208–690 V AC supply range, with a 110–230 V AC control supply.
Instead of applying full motor voltage instantaneously, the ATS480D32Y manages the acceleration process to provide smoother motor startup. This can reduce electrical stress and mechanical shock on equipment such as pumps, fans, compressors, conveyors, and other rotating machinery.
The ATS480 platform also provides torque-control functionality for managing acceleration and deceleration. Depending on the application, it can be used for both in-line and inside-delta motor connections, providing flexibility when designing motor-control systems.
The supplied physical specifications for the ATS480D32Y are 275 × 160 × 203 mm and 4.9 kg. These dimensions correspond to a width of 160 mm, height of 275 mm, and depth of 203 mm.

The published dimensional information places the ATS480D32Y in the ATS480 frame-size-A group, sharing the same 160 × 275 × 203 mm overall dimensions as several other D-series models.
Motor Application Range
The ATS480D32Y has a rated operational current of 32 A. Published ATS480 technical data lists the model for motor applications including approximately 9 kW at 230 V and 18.5 kW at 400 V in the specified heavy-duty/inside-delta configuration data. The actual usable motor rating depends on the connection method, duty, ambient conditions, motor characteristics, and application requirements.
For this reason, motor selection should always be based on motor current and application duty rather than relying solely on motor power.
How the ATS480D32Y Works
The ATS480D32Y uses controlled semiconductor switching to manage the voltage delivered to an asynchronous motor during acceleration and deceleration.
A simplified installation can be represented as:

Normal Operating Condition
During startup, the ATS480D32Y progressively controls the motor’s electrical conditions rather than subjecting the motor to an abrupt full-voltage start.
This can help reduce:
- Starting current
- Torque shock
- Mechanical stress
- Voltage disturbances
- Belt and coupling stress
- Pump and compressor shock
The ATS480 platform also uses torque-control functionality to manage acceleration and deceleration, which is particularly useful for applications where smooth motor behavior is important.
Key Functions
The ATS480D32Y is designed to provide:
- Soft motor starting
- Controlled motor stopping
- Acceleration control
- Deceleration control
- Current management
- Motor protection functions
- Fault monitoring
- Digital control integration
- Modbus communication
- In-line motor connection
- Inside-delta motor connection
The ATS480 family is designed for process, infrastructure, and industrial-machine applications.
Industrial Applications
Pumping Systems
The ATS480D32Y is well suited to applications where smooth motor acceleration and stopping are desirable.
Typical examples include:
- Water pumps
- Cooling pumps
- Process pumps
- Wastewater systems
- Circulation pumps
Controlled stopping can also be valuable where abrupt changes in motor speed could disturb a fluid-handling process.
Fans and Blowers
Industrial fans and blowers often have significant rotating inertia. A controlled acceleration profile can reduce mechanical shock during startup.
Applications include:
- Industrial ventilation
- Exhaust systems
- Process-air systems
- Cooling systems
- Dust extraction equipment
Compressors
The ATS480D32Y can be integrated into compressor motor-control systems where controlled starting is required.
Proper configuration should consider the compressor type, motor characteristics, starting frequency, and mechanical load.
Conveyors
Conveyor systems can benefit from gradual acceleration because abrupt motor torque can cause:
- Belt tension
- Product movement
- Coupling stress
- Gearbox loading
- Mechanical shock
Mixers and Process Machinery
Mixers and other rotating process equipment may require controlled acceleration to prevent sudden torque application.
Installation Guide
1. Verify the Product
Before installation, confirm:
Schneider ATS480D32Y
Inspect the unit for:
- Physical damage
- Cracked housing

- Width: 160 mm
- Depth: 203 mm
Allow additional cabinet space for:
- Power cables
- Control wiring
- Ventilation
- Protective devices
- Cable bending radius
- Maintenance access
Do not design the cabinet around the device dimensions alone.
4. Mounting
The ATS480D32Y belongs to the ATS480 frame-size-A group.
The installation documentation specifies four mounting points using M6 mounting screws for this frame size.
Before tightening the mounting hardware, verify:
- Correct vertical orientation
- Panel strength
- Mounting-hole alignment
- Adequate ventilation
- Cable access
- Maintenance clearance
5. Electrical Isolation
Before electrical installation:
- Disconnect incoming power.
- Apply lockout/tagout procedures.
- Verify absence of hazardous voltage.
- Isolate the motor.
- Confirm stored electrical energy has been safely discharged.

- Stop command
- Reset
- Fault output
- Run status
- External interlocks
- PLC signals
- Emergency-stop logic
Separate control wiring from high-current power conductors where practical.
8. Communication Integration
The ATS480D32Y provides serial communication capability through its control architecture, including Modbus communication.
When integrating with a PLC or supervisory system, verify:
- Communication address
- Baud rate
- Serial settings
- Network wiring
- Control permissions
- Communication status
A communication fault should be distinguished from a power-stage or motor fault.
9. Parameter Configuration
Configure the soft starter according to the actual motor and application.
Important settings may include:
- Motor rated current
- Starting parameters
- Acceleration time
- Deceleration time
- Current limitation
- Protection settings
- Stop mode
- Control source
