Product Overview

The Schneider ATS22C32S6 Soft Starter for Asynchronous Motor is an Altistart 22 motor-control device used to manage the starting and stopping process of asynchronous motors in industrial equipment.

In practical installations, direct-on-line starting can create a sudden electrical and mechanical response. The ATS22C32S6 is used where the motor needs a more controlled transition into operation, helping reduce the impact of starting on the motor, coupling, transmission components, and driven machinery.

Typical applications include pumps, fans, compressors, conveyors, material-handling equipment, and other industrial machines where controlled motor acceleration and stopping are preferred. Its primary role is starting and stopping control rather than continuous variable-speed regulation.

Working Principle

The ATS22C32S6 is installed in the power circuit between the incoming electrical supply and the asynchronous motor.

A simplified arrangement is:

Incoming Power → ATS22C32S6 → Asynchronous Motor → Mechanical Load

During startup, the soft starter controls the electrical conditions applied to the motor so that acceleration takes place progressively rather than through an abrupt direct connection.

This operating method is useful when the driven equipment is sensitive to sudden torque. A conveyor, for example, may require gradual belt acceleration, while a pump system may benefit from a smoother transition when the motor starts.

The starter can also manage the stopping process where the application requires a controlled reduction in motor operation.

The ATS22C32S6 should therefore be viewed as a motor starting and stopping controller, rather than a replacement for a variable-frequency drive in applications requiring continuous speed adjustment.

Industrial Applications

The ATS22C32S6 can be used across a variety of industrial motor-control applications.

The appropriate application should be evaluated according to the motor characteristics, starting conditions, and mechanical load.

Compatible System Components

The ATS22C32S6 normally operates as part of a complete motor-control system.

The starter, motor, protection devices, control circuit, and driven machinery should be evaluated together during system design or replacement.

Installation and Maintenance

The ATS22C32S6 is intended for installation in a suitable industrial electrical enclosure. Its stated 33 kg weight should be considered when planning cabinet mounting, handling, and mechanical support.

Before installation or replacement, confirm the complete model number and check that the starter matches the motor-control application.

Recommended maintenance checks include:

• Confirm the complete ATS22C32S6 model number.
• Verify motor and incoming supply requirements.
• Check power-terminal connections.
• Inspect motor cables and terminals.
• Verify control wiring.
• Check grounding arrangements.
• Ensure adequate 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 difficulties 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 identifying the starter as the source of the problem.

Recommended Related Models

Related Altistart 22 models can be considered according to the motor rating, electrical configuration, and application duty.

A related model should not be selected solely because it has similar dimensions. Motor requirements, electrical supply, starting duty, and load characteristics should be checked before substitution.

Technical FAQs

What is the primary function of the ATS22C32S6?

The ATS22C32S6 is used to manage the starting and stopping of asynchronous motors. It is suitable for machinery where a gradual motor transition is preferable to direct starting.

Why is a soft starter useful for high-inertia equipment?

High-inertia machinery can require a substantial torque response to begin moving. Controlled acceleration makes the transition more gradual and can reduce mechanical stress on couplings, belts, shafts, and other transmission components.

Can the ATS22C32S6 provide continuous motor-speed adjustment?

No. The ATS22C32S6 is primarily a soft starter for controlled acceleration and stopping. Continuous variable-speed operation requires a different type of motor-control device, such as a variable-frequency drive.

What should be checked before installing an ATS22C32S6?

The motor characteristics, incoming supply, starting duty, control wiring, protection arrangement, mechanical load, and complete starter model should be verified. Proper enclosure ventilation and mechanical support should also be considered.
