Motor starting is a deceptively important part of industrial automation. Although the motor itself may operate reliably once running, the transition from standstill to full operating condition can produce substantial electrical and mechanical demands.
The ABB PSE142-600-70 1SFA897110R7000 Soft Starter addresses this part of the motor-control process by providing controlled starting and stopping for compatible applications.
A soft starter can be especially useful where a motor does not require continuous speed adjustment. For example, a pump may normally operate at a fixed speed, but uncontrolled starting can create pressure changes and mechanical stress. A conveyor may also run at a fixed operating speed while still benefiting from smoother acceleration.
The PSE142-600-70 is therefore positioned between simple motor starting and more advanced variable-speed control. It provides dedicated starting control without making continuous speed regulation the central function.
For system integrators, correct application selection is essential. The motor rating, load characteristics, starting frequency, environmental conditions, electrical supply, and required control behavior should all be evaluated before installation.
Maintenance teams should also pay attention to the relationship between the soft starter and the motor. A starter fault does not necessarily mean the starter itself has failed. Motor insulation problems, overloaded machinery, incorrect connections, supply disturbances, and mechanical issues can all produce symptoms that appear to originate from the motor-control device.
The physical design of the PSE142-600-70 is well suited to industrial cabinet installation. Its listed dimensions are 295 × 130 × 220 mm, and its weight is 4.40 kg (9.70 lb).
For industrial users seeking controlled motor starting in fixed-speed applications, the ABB PSE142-600-70 offers a focused and practical motor-control solution.

Large motor applications
The ABB PSE142-600-70 1SFA897110R7000 Soft Starter is a dedicated motor-starting solution for compatible three-phase industrial applications. Measuring 295 × 130 × 220 mm and weighing 4.40 kg (9.70 lb), it combines a practical cabinet footprint with controlled motor-starting functionality. For pumps, fans, compressors, conveyors, and other fixed-speed machinery, the PSE142-600-70 can help provide smoother acceleration and stopping while reducing the impact of motor starting on connected equipment.
Applications
The ABB PSE142-600-70 1SFA897110R7000 Soft Starter is an industrial motor-control device designed to provide controlled starting and stopping for three-phase motors. Instead of applying full motor voltage immediately, a soft starter manages the electrical conditions during acceleration and deceleration, helping reduce the mechanical and electrical stress associated with direct-on-line starting.
The PSE series is well suited to motor-driven equipment where smooth acceleration, controlled stopping, and reduced starting impact are important. Typical applications include pumps, fans, compressors, conveyors, blowers, and other industrial machinery that can benefit from controlled motor starting.
For pump applications in particular, controlled starting and stopping can help reduce sudden changes in the mechanical system. In conveyor and fan installations, smoother acceleration can also contribute to improved equipment behavior and reduced stress on couplings, belts, shafts, and other mechanical components.
The PSE142-600-70 provides a practical solution for installations that require dedicated motor starting equipment without necessarily requiring the full functionality of a variable frequency drive.
With listed dimensions of 295 × 130 × 220 mm and a weight of 4.40 kg (9.70 lb), the unit provides a compact cabinet-mounted solution for industrial motor-control applications.
Advantages
Controlled Motor Starting
One of the main advantages of the ABB PSE142-600-70 is its ability to provide a more controlled motor-starting process than conventional full-voltage starting. Limiting the starting impact can help reduce stress on both the electrical supply and the driven mechanical equipment.
This is particularly useful where large motors are connected to electrical systems that need to manage starting current carefully.
Reduced Mechanical Shock
Sudden motor acceleration can place significant stress on shafts, couplings, gearboxes, belts, and pumps. A soft starter allows the motor to accelerate progressively, helping create a smoother transition from standstill to normal operation.
For industrial machinery with frequent starts, this can be a valuable operational advantage.
Suitable for Common Industrial Motor Loads
The PSE platform is designed for applications involving common motor-driven equipment. Pumps, fans, compressors, conveyors, and similar machinery can benefit from controlled starting and stopping.
This broad application range makes the PSE142-600-70 a practical choice for many industrial motor-control cabinets.
Compact Cabinet Integration
The unit measures 295 × 130 × 220 mm, providing a relatively compact solution for motor-control panels. At 4.40 kg (9.70 lb), it can also be handled conveniently during installation and maintenance.
A Practical Alternative to Conventional Starting Methods
Where speed regulation is not required, a soft starter can provide controlled motor starting without the same application requirements associated with a variable frequency drive. This makes the PSE142-600-70 particularly attractive for fixed-speed motor applications where controlled acceleration is the primary requirement.
Technical FAQs
1. What is the ABB PSE142-600-70 soft starter used for?
It is used to control the starting and stopping process of compatible three-phase motors, helping reduce starting stress on electrical and mechanical systems.
2. What is the difference between a soft starter and a variable frequency drive?
A soft starter primarily manages motor acceleration and deceleration, while a variable frequency drive can control motor speed continuously by adjusting frequency and voltage.
3. Which industrial loads are suitable for a soft starter?
Common applications include pumps, fans, compressors, conveyors, and other fixed-speed motor-driven machinery where smoother starting is beneficial.
4. Why use a soft starter instead of direct-on-line starting?
Direct-on-line starting applies full supply voltage to the motor immediately and can produce high starting current and mechanical shock. A soft starter provides a more controlled transition.
5. Can the PSE142-600-70 control motor speed during normal operation?
A soft starter is not intended to provide continuous variable-speed control like a VFD. Its principal function is controlled starting and stopping.
6. What can cause a soft starter to trip during motor acceleration?
Possible causes include excessive motor load, unsuitable starting parameters, supply problems, motor faults, wiring issues, thermal conditions, or an application that exceeds the starter's capabilities.
7. Why is motor-load selection important?
The starter must be correctly matched to the motor's electrical characteristics and application duty. Incorrect selection can result in nuisance trips, overheating, or unreliable starting.
8. What should be checked if a motor fails to start?
Check incoming power, control signals, motor connections, protection status, starter diagnostics, motor condition, and the configured starting parameters.
9. Can frequent motor starts affect soft-starter operation?
Yes. Repeated starts can increase thermal loading. The permitted starting frequency and application duty should be considered during system design.
10. What should be verified after installing the PSE142-600-70?
Verify motor and supply connections, control wiring, protection settings, starting parameters, fault status, and the motor's acceleration behavior before placing the equipment into normal service.
