Product Overview

The Schneider ATS22C32Q Altistart Soft Starter is a motor-control unit from the Altistart 22 family, used to manage the starting and stopping of asynchronous motors in industrial equipment.

In an actual motor-control cabinet, this type of starter is typically installed between the incoming power circuit and the motor. It is useful when direct-on-line starting would create a sharp current demand or a sudden transfer of torque to the driven machinery. Pumps, fans, compressors, conveyors, and other motor-driven equipment can benefit from a more controlled transition during startup.

The ATS22C32Q is intended for applications where the motor normally operates at its supply frequency and the main requirement is to control acceleration and stopping, rather than continuously adjust motor speed.

Working Principle

The ATS22C32Q sits in the motor power circuit and manages the electrical conditions applied to the motor during starting.

A typical arrangement is:

Incoming Power → ATS22C32Q → Asynchronous Motor → Mechanical Load

With direct starting, the motor is subjected to the supply immediately. The resulting starting current and torque can place additional stress on the electrical system and mechanical transmission.

With the ATS22C32Q, the startup transition is controlled so that the motor accelerates progressively. This is useful on equipment where sudden acceleration can cause belt movement, coupling shock, pressure changes, or unnecessary stress on the driven machinery.

The starter can also manage the stopping process when the application requires a controlled deceleration.

Unlike a variable-frequency drive, the ATS22C32Q is primarily concerned with starting and stopping control rather than continuous speed adjustment.

Industrial Applications

The ATS22C32Q can be used in industrial installations where asynchronous motors require a controlled starting process.

The actual application should be evaluated according to the motor characteristics and mechanical load.

Compatible System Components

The ATS22C32Q normally operates as one part of a complete motor-control installation.

The soft starter should be selected together with the motor, electrical protection, control system, and driven equipment.

Installation and Maintenance

The ATS22C32Q is intended for installation in a suitable industrial electrical enclosure. The stated 33 kg weight should be taken into account when planning cabinet mounting and mechanical support.

Before commissioning or replacing the unit, verify the complete model number and the requirements of the motor-control application.

Recommended checks include:

• Confirm the complete ATS22C32Q model number.
• Verify the motor and incoming supply requirements.
• Check power connections and terminals.
• Inspect motor cables.
• Verify control wiring.
• Check grounding arrangements.
• Confirm suitable cabinet 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 remain.
• Perform a controlled test run after installation.

If the motor does not accelerate correctly, the motor, load, power supply, wiring, protection devices, and starter configuration should all be considered during troubleshooting.

Recommended Related Models

For an Altistart 22 installation, related models should be selected according to motor requirements and application conditions.

A related model should not be selected solely according to physical dimensions. Motor requirements, electrical configuration, starting duty, and load characteristics should be checked before substitution.

Technical FAQs

What is the ATS22C32Q used for?

The ATS22C32Q is used to manage the starting and stopping of asynchronous motors. It is suitable for industrial machinery where direct motor starting would create an undesirable electrical or mechanical transition.

Why would a conveyor system use a soft starter?

A conveyor can experience a sudden mechanical load when its motor starts directly. Controlled acceleration can make the transition less abrupt and reduce the starting impact on belts, couplings, and other transmission components.

Can the ATS22C32Q regulate motor speed during normal operation?

The ATS22C32Q is a soft starter rather than a variable-frequency drive. Its primary function is to control motor starting and stopping, not to provide continuous variable-speed operation.

What should be checked when replacing an ATS22C32Q?

The complete model number, motor requirements, incoming power, starting duty, control wiring, protection arrangement, and mechanical load should be checked. The replacement should match the actual application rather than being selected only by physical size.
