Step 7 Drive Es Simotion Download

Drive ES Basic is a software for starting, parameterizing, optimizing and diagnosing Siemens actuators (DriveMonitor / SIMOCOM U). The Drive starters (DriveMonitor; SIMOCOM U / A, Starter) have the full range of components in Drive ES Basic, thus allowing the user to deal with the actuators at the same time as Siemens automation engineering. The management data of both the automatic and the technical drive match. That ensures normal data storage. With the Drive ES software, the Siemens actuators are fully integrated into the TIA.

This helps to identify the cause of a breakdown or failure and greatly facilitates the diagnosis of equipment. Analysis of errors or warning codes is the first step in determining the causes of a breakdown or failure. Correct decoding helps to understand and eliminate the malfunction or failure of the frequency converter and all elements of the electric drive. Today we will consider what frequency converters are manufactured by Siemens and what error codes occur when this equipment fails.

The Siemens frequency converter is designed to control the speed of motors that drive various technological installations in production, construction, household, and transport.

The variety of proposed solutions for frequency converters for asynchronous electric motors creates opportunities for solving any problems of the electric drive. Digitalization of technical solutions makes it possible to control the speed and torque of the actuator with high accuracy and efficiency. This ensures efficiency and productivity along with ease of commissioning and maintenance. There are both monoblock designs that allow the most compact placement, and modular devices with wide functionality. Modular elements allow, depending on the required parameters, to create various combinations of power and control elements, and select various communication interfaces for use - PROFIBUS-DP, PROFINET, CANopen and connect external devices.

In the range of branded products, you can find a siemens frequency converter for any field of operation. For example, one of the most widespread and demanded model lines is sinamics G110. It serves to control the speed of three-phase motors with a power of 120 W - 3.0 kW in single-phase networks. micromaster 420 regulates the speed of standard drives and generally helps to automate the technical process. There is an exclusive siemens pump and fan series - these are micromaster 430 frequency converters. The largest control range is for the micromaster 440 series.

Benefits of using Siemens frequency converters:

Brushless DC motors that are commutated with traditional "6-step" control are susceptible to increased instability and therefore noise at the Hall sensor boundaries. As the motor rotates, when entering each new Hall state, the current flowing through the coils changes abruptly. This is what advances the commutation as the motor rotates.

While not every application can support the cost of a direct drive motor (and they have their own control challenges anyways), it may be that your machine just needs the next level of ball screw quality, a better coupling, more rigid framing, or some weight redistribution.

A less painful way of minimizing current ripple or 'saw toothing' is to increase the switching frequency of your drive, or select a new drive with a higher switching frequency. A higher switching frequency will reduce the magnitude of the current ripple due to switching, and thus lower waste heat generation.

This may only be possible if you are building your own drive, but switching amplifier configurations such as H-Bridges, which are commonly used to control step motor and DC Servo motor coils, can be controlled in several different ways. While a full description is beyond the scope of this article, different techniques have different heat generation characteristics.

When actually moving a load, step motors generally have a heat disadvantage compared to servo motors because step motors must be driven with a current that is able to overcome the axis' highest possible resistive force, whether or not that force is present at any given moment.

For example, if a machine is designed to lift a load of 2 kg but is only loaded with a load of 1 kg, the step motor is still driven with enough current to lift the 2 kg load, whereas the servo motor will apply exactly enough energy to lift the 1 kg load.

Despite these fundamental challenges, one approach to lowering step motor heat generation is to recognize that in dynamic operation many axes of the machine will have downtime. In this case, switching the step motor to a lower 'holding command' will reduce average heat generation. You want enough holding torque to keep the load from moving, but a low enough value to lower heat output while the axis is at rest.

Step motors have the reputation of cranking out nice, repeatable steps. But the more you ask of your step motor and controller, the more you will notice that resolution does not equal accuracy or even repeatability.

A primary culprit in step motor accuracy problems stems from the fundamental electromotive force generation inherent to a step motor. When you excite the coils at a certain phase angle, you define a roughly sinusoidal force 'valley' that your motor will settle into. Think of a ball rolling to the bottom of a trough. But if the valley has a gentle slope, as this one does, an outside force will tend to push the axis 'up the hill' to one side or the other. This means you won't quite be at the step location (the exact bottom of the valley) you expected.

Another general solution to the accuracy problem is to use a motor with more phases. A standard step motor has two phases, however motors can also be purchased from various vendors that provide 3 or 5 phases. More phases means a narrower force 'valley' and therefore better accuracy.

This is an expensive trick in the sense that it will cost you move time, but both step motors and servo motors can benefit in their final positioning accuracy by always approaching from the same direction.

Another source of accuracy error is that even when presented with a perfectly sinusoidal micro-stepping waveform, step motors do not increment in perfectly linear steps. Over the course of a full step cycle, when measured to a high accuracy, you will find that the actual position differs from the theoretical straightline motion by anywhere from 3 to 20% depending on the motor, and whether it has features like a skewed rotor.

To correct this, you can electronically build a compensating table so that instead of a perfect sinusoid, you drive the motor with a modified waveform that linearizes the motion. Note that this technique will improve, but not eliminate, motor-specific non-linearities. 006ab0faaa
