Product Overview
The Schneider ATS22C32S6U Soft Starter for Asynchronous Motor is an Altistart 22 motor-control device used to manage the starting and stopping of asynchronous motors in industrial equipment.
It is particularly useful in motor-driven systems where direct starting can produce a sudden current demand and abrupt mechanical torque. By controlling the motor’s transition into operation, the ATS22C32S6U can help make startup more gradual and reduce the impact placed on mechanical transmission components and driven equipment.
Typical applications include pumps, fans, compressors, conveyors, material-handling systems, and general industrial machinery. The unit is intended primarily for controlled starting and stopping rather than continuous variable-speed operation.

Working Principle
The ATS22C32S6U is connected in the motor power circuit between the incoming electrical supply and the asynchronous motor.
A simplified system arrangement is:
Incoming Power → ATS22C32S6U → Asynchronous Motor → Mechanical Load
During startup, the soft starter manages the electrical conditions applied to the motor so that acceleration takes place progressively. This avoids the abrupt transition associated with conventional direct starting.
The controlled acceleration can be beneficial on equipment with belts, couplings, shafts, pumps, or other mechanical components that are sensitive to sudden torque.
During stopping, the starter can also provide a controlled transition where the application requires it.
The ATS22C32S6U is therefore primarily a soft starting and stopping device. It should not be treated as a variable-frequency drive for applications requiring continuous motor-speed regulation.
Industrial Applications
The ATS22C32S6U can be used in a variety of industrial motor-control systems.
| Application | Typical Use |
|---|---|
| Pump Systems | Controlled motor startup and stopping |
| Industrial Fans | Gradual fan acceleration |
| Compressors | Controlled starting under load |
| Conveyor Systems | Reduced starting shock |
| Material Handling | Controlled motor acceleration |
| HVAC Equipment | Motor starting control |
| Process Machinery | Controlled asynchronous motor startup |
| General Industrial Equipment | Soft start and stop |
The actual suitability depends on the motor characteristics, starting conditions, and connected mechanical load.
Compatible System Components
The ATS22C32S6U normally forms part of a complete motor-control installation.
| Component | Function |
|---|---|
| ATS22C32S6U | Controls motor starting and stopping |
| Asynchronous Motor | Converts electrical power into mechanical rotation |
| Circuit Protection | Protects the incoming power circuit |
| Motor Protection Device | Provides motor protection |
| Main Contactor | Switching and electrical isolation |
| Control System | Provides start and stop commands |
| Motor Cable | Connects the starter to the motor |
| Mechanical Load | Receives the motor’s mechanical output |
The starter should be evaluated together with the motor, protection equipment, control system, and mechanical load during installation or replacement.
Installation and Maintenance
The ATS22C32S6U is intended for installation in a suitable industrial electrical enclosure. Its stated 33 kg weight should be considered when planning cabinet mounting and mechanical support.
Before installation or replacement, verify the complete model number and the requirements of the motor-control application.
Recommended checks include:
- Confirm the complete ATS22C32S6U model number.
- Verify motor and incoming supply requirements.
- Check power-terminal connections.
- Inspect motor cables and terminals.
- Verify control wiring.
- Check grounding arrangements.
- Ensure sufficient enclosure ventilation.
- Inspect terminals for looseness or overheating.
- Review the starter configuration after replacement.
- Check the mechanical load if acceleration is abnormal.
- Inspect the motor if starting problems continue.
- Perform a controlled test run after installation.
If abnormal starting occurs, the motor, load, electrical supply, protection devices, control signals, and starter configuration should all be checked before determining that the soft starter is defective.

Technical FAQs
What is the ATS22C32S6U used for?
The ATS22C32S6U is used to control the starting and stopping of asynchronous motors. It is suitable for industrial machinery where a gradual motor transition is preferred.
How does the ATS22C32S6U help during motor startup?
It manages the motor’s startup conditions so acceleration occurs more progressively. This can reduce sudden mechanical torque and make startup less abrupt for the connected equipment.
Is the ATS22C32S6U suitable for variable-speed applications?
It is primarily a soft starter for controlled starting and stopping. It does not serve the same purpose as a variable-frequency drive used for continuous motor-speed adjustment.
What should be checked before replacing an ATS22C32S6U?
Verify the complete model number, motor characteristics, incoming supply, starting duty, control wiring, protection equipment, and mechanical load. These factors determine whether the replacement is appropriate for the application.
