Product Overview
The ABB PSE142-600-70 1SFA897110R7000 Soft Starter is an electronic motor starting and stopping device for controlling three-phase induction motors. It limits the electrical and mechanical stress that can occur during direct-on-line starting by controlling the motor voltage during acceleration.
The PSE Series is suited to applications where motors drive pumps, fans, compressors, conveyors, and other equipment that benefit from controlled starting and stopping. In pump systems, for example, controlled motor acceleration and deceleration can help reduce abrupt changes in flow and mechanical shock.
Unlike a conventional contactor that applies full line voltage immediately, a soft starter manages the motor’s starting profile through power semiconductor switching. Once the motor reaches the required operating condition, the starter can operate with reduced semiconductor losses through its bypass arrangement.
The PSE142-600-70 can be incorporated into motor control panels where the starter works alongside protective devices, control circuitry, and the driven machine. Proper selection should consider the motor rating, starting duty, load characteristics, and applicable installation requirements.

Working Principle
The soft starter controls the voltage applied to the motor during the starting sequence. Power semiconductor devices regulate the electrical waveform so that the motor voltage increases progressively rather than being applied at full level immediately.
As the applied voltage rises, motor torque increases and the motor accelerates toward operating speed. The acceleration behavior depends on the motor characteristics, load torque, and configured starting parameters.
During stopping, the soft starter can control the motor voltage according to the configured stopping method. This is particularly useful for loads where an abrupt removal of motor power can produce undesirable mechanical effects.
Incoming Power → PSE142 Soft Starter → Motor → Mechanical Load
After the starting sequence, the bypass function can transfer the motor current through a lower-loss path while the motor continues to operate. The exact operating behavior depends on the starter configuration and application.
Role in a Motor Control Architecture
The PSE142-600-70 occupies the motor-starting and stopping layer between the electrical supply and the motor. It normally works together with upstream protection, control commands, and downstream motor equipment rather than replacing the complete motor protection system.
Power Supply → Protection / Switching → PSE142 Soft Starter → Motor → Driven Equipment
| System Element | Function |
|---|---|
| Incoming Power Supply | Provides electrical power to the motor circuit |
| Circuit Protection | Protects the electrical installation against faults |
| Control System | Provides start, stop, and operating commands |
| PSE142 Soft Starter | Controls motor acceleration and stopping |
| Motor | Converts electrical energy into mechanical power |
| Driven Equipment | Performs the required pumping, conveying, compressing, or fan operation |
| Monitoring / Protection | Supervises motor and system operating conditions |
The starter can therefore be integrated into a conventional motor control center or machine control panel while the higher-level controller manages operating commands and process sequencing.
Industrial Applications
| Application | Typical Use |
|---|---|
| Water Pumps | Controlled pump starting and stopping |
| HVAC Fans | Reduced mechanical stress during fan startup |
| Industrial Fans | Controlled acceleration of ventilation equipment |

| Material Handling | Reduced starting shock in motor-driven equipment |
| Process Machinery | Motor control within automated production systems |
| Industrial Motor Panels | Soft-start control for three-phase induction motors |
Installation and Maintenance
- Verify that the PSE142-600-70 is correctly selected for the motor and application duty.
- Check the motor nameplate and compare its electrical requirements with the starter configuration.
- Confirm the incoming supply and motor wiring against the approved electrical schematic.
- Install appropriate upstream circuit protection and switching equipment.
- Ensure power and control terminals are correctly identified before energizing the starter.
- Route power and control wiring according to the control-panel installation requirements.
- Verify that the motor rotation and mechanical load direction are correct during commissioning.
- Configure the starting and stopping parameters according to the motor and driven load.
- Test the acceleration sequence under controlled operating conditions.
- Check the starter and motor for abnormal current, heating, noise, or vibration during operation.
- Inspect electrical connections and ventilation conditions during scheduled maintenance.

Technical FAQs
When should the PSE142-600-70 be selected instead of a direct-on-line starter?
A soft starter is useful when the motor or driven equipment requires reduced starting stress, controlled acceleration, or a more gradual stopping sequence. The application should be evaluated based on motor rating, load characteristics, starting frequency, and required starting torque.
Can the PSE142 be used for a pump with frequent starts and stops?
It can be applied to pump systems where controlled starting and stopping are beneficial, but the actual suitability depends on the motor duty, pump characteristics, number of starts per hour, and the configured operating conditions. These factors should be checked before final selection.
What can cause a soft starter to trip during motor acceleration?
Possible causes include an unsuitable motor/load combination, excessive starting demand, incorrect configuration, electrical supply problems, wiring issues, or motor-related faults. Checking the motor current and starter operating conditions during acceleration can help identify the cause.
Why is a bypass arrangement used with a soft starter?
A bypass path can reduce the losses associated with the power semiconductor switching devices once the motor has completed its starting sequence. This allows the starter to provide controlled acceleration while supporting normal motor operation through a lower-loss current path.
