Product introduction

The ABB PSTX570-600-70 is a high – performance soft starter that belongs to ABB’s advanced PSTX series. Soft starters play a crucial role in the smooth start – up and shutdown of electric motors, and the PSTX570-600-70 is no exception. It is designed to provide precise control over the starting and stopping process of three – phase motors, ensuring reduced mechanical stress and electrical current surges.

With a rated maximum operational current of 570 A and an operating voltage range from 208 to 600 V AC, the PSTX570-600-70 can handle a wide variety of medium – to – large – sized motor applications. Its three – phase control mechanism enables a safe and gradual start – up for motors, which is essential for protecting both the motor and the connected equipment. This soft starter also features a built – in bypass, which not only simplifies the installation process but also contributes to energy savings during normal motor operation.

Core advantages and technical highlights

Torque control for pump applications

The ABB PSTX570-600-70 offers excellent torque control, making it particularly suitable for pump applications. In pumping systems, precise torque control ensures smooth operation, reduces water hammer effects, and extends the lifespan of pumps and related piping. For example, in a water treatment plant, the soft starter can regulate the torque to start and stop the pumps gently, preventing sudden pressure changes that could damage the pipes or the pumps themselves.

Coated circuit boards for durability

Featuring coated circuit boards, the PSTX570-600-70 is highly resistant to dust, moisture, and corrosive air. This makes it suitable for use in harsh industrial environments such as chemical plants or food processing facilities where the presence of contaminants could otherwise affect the performance and lifespan of the equipment. The protective coating on the circuit boards helps maintain the integrity of the electrical components, reducing the need for frequent maintenance and ensuring reliable operation over time.

Multiple communication options

This soft starter comes with a wide range of communication capabilities. It has a built – in Modbus RTU interface, which allows for easy integration with other industrial devices in a network. Additionally, optional Anybus modules can be added to support major communication protocols like Profinet, Profibus, Modbus TCP, and Ethernet IP. This flexibility in communication enables seamless connectivity with different types of control systems, such as PLCs or SCADA systems, facilitating centralized monitoring and control of motor operations in large – scale industrial automation setups.

User – friendly interface

The PSTX570-600-70 is equipped with a detachable full – graphic display that has an IP66 protection rating, making it suitable for both indoor and outdoor use. The display provides clear and detailed information about the soft starter’s operation, including status indicators, parameter settings, and diagnostic messages. With 14 languages available, it is easy for operators around the world to set up and monitor the soft starter. The three programmable digital inputs and hardwire inputs for start/stop/reset of faults also offer convenient ways to control the device.

Typical application scenarios

Pumping systems

In water supply networks, the ABB PSTX570-600-70 is widely used to start and stop pumps. For instance, in a large – scale irrigation project, multiple pumps are used to distribute water over a vast area. The soft starter’s ability to provide a smooth start – up and stop helps prevent water hammer, which could cause damage to the pipes and pumps. Its torque control feature also ensures that the pumps operate efficiently, reducing energy consumption and maintenance costs. In wastewater treatment plants, the soft starter can control the pumps that transfer sewage, handling the high – inertia loads of the pumps with ease and ensuring continuous operation.

Compressor applications

Compressors in industrial settings, such as those in manufacturing plants or gas refineries, require a smooth start – up to avoid sudden mechanical stress. The PSTX570-600-70 is ideal for this purpose. When starting a compressor, the soft starter gradually increases the voltage and torque, minimizing the inrush current. This not only protects the compressor motor but also the power supply system. In a natural gas processing plant, the compressors that increase the pressure of the gas for transportation need to start and stop smoothly. The ABB PSTX570-600-70 can be programmed to meet the specific requirements of these compressors, ensuring stable operation and reliable performance.

Conveyor systems

Conveyor belts are commonly used in industries like mining, logistics, and manufacturing to transport materials. The ABB PSTX570-600-70 can be used to control the motors that drive these conveyor belts. In a mining operation, large – capacity conveyor belts are used to transport ore from the mining site to the processing plant. The soft starter’s ability to provide a controlled start – up and stop helps prevent the belts from jerking, which could lead to material spillage or damage to the conveyor system. The jog function of the soft starter also allows for easy positioning and adjustment of the conveyor belt during maintenance or loading operations.

Related model recommendations

• PSTX300-600-70: A lower – current variant of the PSTX series. It is suitable for applications where the motor current requirements are less than those of the PSTX570-600-70. It has a similar feature set but with a lower rated operational current, making it a cost – effective option for smaller – scale industrial processes.
• PSTX720-600-70: An upgrade in terms of current – handling capacity compared to the PSTX570-600-70. It can be used in applications where larger motors with higher current demands need to be controlled. It offers the same advanced features such as torque control and multiple communication options but is designed for more power – hungry motors.
• PSS Universal series: This series is also from ABB and offers a range of soft starters suitable for different motor sizes. The PSS series has different models that can be used as alternatives or in complementary setups with the PSTX570-600-70. For example, in a large industrial complex where there are motors of various sizes, the PSS series can be used for smaller motors, while the PSTX570-600-70is reserved for larger, more critical motor applications.
• PSR Compact series: ABB’s PSR series is a compact – sized option. It is more space – efficient and can be used in applications where physical space is limited. Although it may have different form factors and some differences in features compared to the PSTX570-600-70, it can still be used in certain scenarios where the requirements are less demanding, such as in small – scale manufacturing units or in equipment with tight installation spaces.
• ACS580 Inverter: While not a soft starter like the PSTX570-600-70, the ACS580 inverter from ABB can be used in applications where variable – speed control of motors is required. In some cases, depending on the application needs, a combination of the PSTX570-600-70for smooth start – up and an ACS580 for variable – speed operation can provide an optimal solution for motor control in industrial processes.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing the ABB PSTX570-600-70, ensure that the installation environment meets the requirements. The ambient temperature should be within the range of – 25°C to +60°C, and the relative humidity should be appropriate to avoid condensation. The installation area should be free from excessive dust, moisture, and corrosive substances. Use appropriate tools such as torque wrenches to fasten the connections securely.
