Product Overview

The Schneider Electric ATS490C41Y Soft Starter is a high-current motor starting and stopping device from the Altivar Soft Starter ATS490 family. It is designed for industrial three-phase asynchronous motors where controlled acceleration, controlled stopping, reduced mechanical stress, and integration with automation systems are required.

The ATS490C41Y is intended for demanding motor-driven equipment such as pumps, fans, compressors, conveyors, mixers, material-handling equipment, and process machinery. By controlling the motor during startup and stopping, the soft starter can provide a smoother transition than conventional direct-on-line starting.

What Is the ATS490C41Y?

The ATS490C41Y is installed between the industrial power system and a three-phase motor.

A typical system arrangement is:

Three-Phase AC Supply

Protection / Disconnect Device

ATS490C41Y Soft Starter

Three-Phase Motor

Pump / Fan / Conveyor / Compressor / Machine

The primary purpose of the soft starter is to manage the motor’s transition from standstill to normal operating speed.

A large industrial motor can produce a substantial electrical and mechanical impact when connected directly to the supply. The ATS490C41Y provides controlled starting behavior, allowing engineers to adapt acceleration to the characteristics of the motor and driven machine.

This is particularly useful where sudden torque changes can cause:

  • Mechanical shock
  • Belt tension changes
  • Coupling stress
  • Gearbox stress
  • Shaft stress
  • Hydraulic pressure fluctuations
  • Excessive process disturbance

410 A High-Current Motor Control

The ATS490C41Y belongs to the higher-current range of the ATS490 family.

The supplied model designation corresponds to a 410 A normal-duty current class.

For correct selection, the motor’s actual rated current must be compared with the starter’s applicable current rating.

Engineers should not select the starter solely according to motor horsepower.

The following factors should also be evaluated:

  • Motor rated current
  • Motor voltage
  • Motor frequency
  • Starting torque
  • Load torque
  • Acceleration time
  • Number of starts per hour
  • Duty cycle
  • Ambient temperature
  • Installation altitude
  • Cabinet cooling
  • Heavy-duty requirements

A motor with the same nominal power as another motor can require a different starter size if its load and starting conditions are different.


Motor Voltage Compatibility

The ATS490 platform is designed for a wide industrial motor supply range.

The applicable range for this product family is:

208–690 V AC

Before installation, always compare the motor nameplate with the electrical system design.

Verify:

  • Rated motor voltage
  • Rated motor current
  • Frequency
  • Motor connection
  • Motor power
  • Operating duty

Incorrect voltage or current configuration can cause starting problems and protective trips.


Main Functions

Controlled Starting

The ATS490C41Y regulates motor acceleration to reduce the abrupt electrical and mechanical impact associated with direct starting.

Torque Control

Torque control provides greater flexibility when adapting the starting process to the connected machine.

Controlled Stopping

Controlled deceleration can be useful when sudden stopping could negatively affect the process or mechanical equipment.

Internal Bypass

The internal bypass allows the starter to transition to normal motor operation after the starting sequence.

Motor Monitoring

The ATS490 platform provides information that can help operators and maintenance personnel evaluate motor operation.

Power and Energy Monitoring

Operational information can assist with energy management and process monitoring.

Communication

The ATS490C41Y can be incorporated into automation networks using communication technologies such as:

  • Modbus Serial
  • Modbus TCP
  • EtherNet/IP

Diagnostic Functions

Diagnostic information can help technicians distinguish between electrical, mechanical, configuration, and communication problems.


How the ATS490C41Y Works

1. Start Command

The starter receives a start command from a local control circuit, PLC, HMI, SCADA system, or other control source.

The system verifies the relevant enable and interlock conditions.


2. Controlled Acceleration

The ATS490C41Y controls the motor’s acceleration according to the configured starting parameters.

The objective is to provide sufficient torque to accelerate the motor while avoiding unnecessary mechanical impact.


3. Motor Reaches Operating Speed

As the motor approaches normal operating conditions, the starting phase is completed.

The starter transitions toward its normal running condition.


4. Bypass Operation

The integrated bypass function allows the motor to operate efficiently after starting.

This is particularly valuable in applications where the motor remains continuously operational for long periods.


5. Normal Motor Operation

During normal operation, the control system can monitor:

  • Running state
  • Fault state
  • Motor information
  • Communication status
  • Process information
  • Diagnostic information

6. Controlled Stop

When a stop command is received, the ATS490C41Y applies the configured stopping behavior.

The exact response depends on the application and programmed settings.


Industrial Applications

Pumping Systems

The ATS490C41Y can be used for appropriately rated pump motors in:

  • Water treatment
