Product Overview
The Schneider ATS22D62S6 Soft Starter is a reliable motor control device from the Schneider Electric Altistart 22 (ATS22) series, developed to provide smooth starting and stopping for three-phase induction motors used in industrial automation systems. By controlling the motor voltage during acceleration and deceleration, the soft starter reduces electrical inrush current while protecting both the motor and connected mechanical equipment from excessive stress.
Instead of applying full voltage immediately like a conventional direct-on-line starter, the ATS22D62S6 gradually increases motor voltage during startup. This significantly reduces torque shock, minimizes wear on transmission components, and improves the overall reliability of pumps, conveyors, compressors, fans, and other rotating machinery.
As part of the Altistart 22 family, this soft starter is widely used in manufacturing facilities, water treatment plants, HVAC installations, mining operations, and process industries where dependable motor starting is essential.
With compact dimensions of 295 × 145 × 207 mm and a weight of approximately 12 kg, the ATS22D62S6 is designed for installation inside industrial control cabinets and motor control centers while maintaining excellent accessibility for maintenance and servicing.

Function and Working Principle
The ATS22D62S6 controls motor acceleration by gradually increasing the voltage delivered to the motor windings. Rather than exposing the motor to a sudden surge of current, the soft starter allows the motor to reach operating speed progressively.
The operating sequence can be simplified as:
Power Supply
↓
ATS22D62S6 Soft Starter
↓
Three-Phase Motor
↓
Industrial Equipment
During startup, semiconductor devices regulate the output voltage according to preset acceleration parameters. This allows the motor torque to build smoothly while limiting starting current.
When the motor reaches normal operating speed, the motor continues running under full supply conditions according to the system configuration.
During stopping, the soft starter gradually reduces voltage, allowing controlled deceleration and reducing mechanical impact on the driven equipment.
Role in Industrial Automation Systems
Within an industrial control system, the ATS22D62S6 functions as the motor starting interface between the electrical distribution system and the motor.
A typical control architecture includes:
Power Distribution
↓
Circuit Breaker
↓
ATS22D62S6 Soft Starter
↓
Three-Phase Motor

Industrial Machine
The PLC determines when the motor should start or stop, while the soft starter manages acceleration and deceleration to protect both electrical and mechanical systems.
This arrangement improves equipment reliability while reducing maintenance requirements.
