SIRIUS Soft Starter ES (TIA Portal) is software from Siemens Automation. The Soft Starter ES (TIA Portal) helps you to configure, commission, operation, and diagnostics of the Siemens SIRIUS soft starters devices. We can connect the PC or programming device to the Siemens SIRIUS soft starter devices via the local interface on the Soft starter HMI High Feature.
Due to its exceptional functionality, the intelligent SIRIUS 3RW55 soft starter can solve even the most difficult starting and stopping tasks simply and particularly gently. Integrated smart functions (for example, pump cleaning, pump stopping, automatic parameterization, condition monitoring) help operators to run their pumps smoothly. Thanks to the SIRIUS 3RW55 Failsafe soft starters with integrated Safe Torque Off (STO) functionality, safety-related applications can also be realized.
Test the new generation of 3RW55 soft starters and simply experience how easy commissioning is. With the SIRIUS Soft Starter ES software, you can set parameters, monitor and perform diagnostics for service tasks quickly and easily. You can set the device parameters of the 3RW55 directly from your PC or laptop.
One considerable advantage of SIRIUS 3RW55 soft starters is their media redundancy thanks to the new Profinet High Feature communication module and its integrated Ethernet switch. It provides a ring topology in which communication can be maintained via a second port even if the power fails.
All SIRIUS soft starter have a wide-range voltage versions, so that even if there is a voltage dip, the continued operation of the soft starter, the motor and the application is ensured. This level of electrical ruggedness means that operation is secured even in power supply systems with sporadic voltage dips.
A soft starter is an additional device that can be added to a typical AC electric motor that will allow the motor to use a different startup method. The purpose of this device is to reduce the strain put on the motor during the typical power-up phase of a motor.
To accomplish this, a soft starter will slowly and gradually begin applying increasing voltages to the motor. This allows for a smooth acceleration of power instead of a sudden and violent burst of power that could potentially cause damage to the motor and the machine as a whole.
Essentially, a motor soft starter works by controlling the amount of voltage running through the motors circuits. It does this by limiting torque in the motor. This in turn allows the soft starter to reduce the voltage and allows it to gradually stop reducing the voltage to allow for a smooth progression of current.
In addition to this, certain soft starter models may use solid-state devices. These devices are another means of controlling the amount of electrical current allowed to flow through the motor. This lets the soft starter control the current in three separate, distinct phases to allow for more precise levels of control.
Mechanical soft starters rely on clutches and different couplings that use fluids, steel shot or magnetic forces to reduce the amount of torque in the motor. As discussed earlier, this limits the voltage allowed to surge through the motor and allows it to power up more gently and easily.
However, there are plenty of motors that will greatly benefit from having a soft starter installed and some motors will benefit more than others. This is because certain motors are more susceptible to breaking down and wearing out due to excess amounts of electrical current during their startup phase. Here are just a few of the places where soft starters are commonly used to ease the startup process:
Reducing the amount of energy your machines require is always an ideal goal. It only makes sense that a soft starter would contribute to this. With a conventional start, the motor immediately begins expending the maximum amount of energy and continues to do so for the entire time the motor is running.
A VFD has some similarities to a soft starter, but there are enough differences to put it in a class of its own. Officially known as a Variable Frequency Drive , a VFD is a motor control device that controls the speed of an AC induction motor. This means it can control how fast the motor is running during both the start and stop cycles, as well as during the ordinary run cycle. 2b1af7f3a8
