Variable Speed Drive Schneider ATV950

In autonomous power supply systems, frequency converters are widely used, which are able to simultaneously increase or decrease the frequency of the current, and stabilize the voltage of the power source. These positive properties of frequency converters make it possible to improve the operational and technical characteristics of an autonomous power supply system in the complex. In this article, we will take a closer look at one of the advanced models of variable speed drives – Schneider Electric Altivar Process ATV950.

Schneider Electric Altivar Process ATV950

Variable speed drives are used to regulate the operation of an asynchronous motor in order to prevent a decrease in its efficiency, special devices are used - a frequency converter. Their job is that they smoothly change the speed of rotation of the engine by changing the frequency of the supply voltage.

In an asynchronous motor, the voltage for operation is most often supplied through a circuit breaker connected in series. That is, this way of starting the engine is called differently - soft start. Thus, this provokes a high increase in the current of the starting winding, which will end very badly for the equipment.

The frequency converter has an important relation to this - it controls the current of the electric motor. Forming the required voltage of the desired amplitude and frequency, the frequency converter supplies them to the engine.

Altivar Process is a new series of frequency converters from Schneider Electric that provides high-quality vector control of motors in almost all industries.

Schneider Altivar 950 frequency converters have a large set of hardware and software. In particular, integrated or can be added:

  • Safety and automatic control functions that meet the requirements of most process plant control systems.
  • Additional communication modules that allow the frequency converter to be used in systems built using the main industrial protocols.
  • The number of configurable inputs/outputs is sufficient to implement control.
  • Clear commissioning algorithm using a graphical terminal.
  • Local and remote control of parameters using the built-in web server.
  • Energy-saving modes, ensure a low level of distortion of the mains.
  • Built-in EMC filter.

Depending on the version, Altivar Process ATV950 frequency converters are available in several mounting options and protection levels. ATV 950 drives for wall mounting. This model has an IP55 degree of protection, power range from 0.37kW to 75kW, ready for use in harsh conditions indoors or outdoors to reduce the length of the motor cable.

Schneider offers following main series: ATV950C, ATV950D, ATV950U.

Also in the line is a frequency converter model for outdoor installation ATV950F, with a degree of protection IP54. This model supports a power range from 90 kW to 250 kW. The ATV950F is a packaged device with minimum overall dimensions, suitable for use in normal or harsh environments.

Frequency converters have a wide scope, more and more enterprises of various activities are starting to use frequency converters more often. as there are many advantages to this, but more on that below:

  • Oil and gas industry (pumps, fans, compressors, etc.).
  • Metallurgy and mining (smoke exhausters, conveyors, water supply, crushers).
  • Food industry (mixers, centrifuges, separators, pumps).
  • Civil engineering (ventilation, water supply).

Schneider Altivar ATV950 Setting

The adjustment of the variable speed drive is carried out strictly according to the manufacturer's instructions and taking into account the specifics of the task, which is solved by means of the equipment in which the engine is installed.

For example, if a scalar-type induction motor is used, then the signal amplitude and output frequency are set according to a certain formula. For other types of motor, motor shaft speed sensors are usually used. Therefore, before installing this device, be sure to read the Schneider Altivar ATV650 manual.
