An overview of the

Absolute value encoder

A position encoder that provides the position of the drive system as an absolute real value immediately after it is powered on.If it is a single-turn encoder, the signal acquisition range is one turn;If it is a multi-turn encoder, the signal acquisition range is many turns (for example, 4096 turns is typical).When the absolute value encoder is used as a position encoder, there is no need for a change run after switching on, and therefore no reference switch (for example, BERO) is required.

There are rotary and linear absolute value encoders.

Absolute value encoder example:

The supplied 1FK and 1FT motors can be equipped with an integrated multi-turn absolute encoder, with 2048 sine/cosine waveform signals per turn, more than 4096 absolute revolutions, and → “ENDAT protocol”.Siemens SINAMICS S120 supplier

Adjust the feed

A function that uses the feed from the “modulated power module”, including the additional components required (filters, switchgear, the calculated power portion of the “controller”, voltage detection, etc.)

Regulating interface module

The module includes input side components required for the “modulated power module”, such as the precharge circuit (precharge contactor and buffer protection function).

Active rectifier unit

A controlled, self-commutating feed/feedback device with IGBT in the feed/feedback direction provides a stable DC link voltage for the motor module.The active line module and the line reactor operate in concert as a pressurized converter.

Asynchronous motor

Asynchronous motor is a kind of AC motor, its speed is less than the synchronous speed.

The induction motor can be connected directly to the three-phase power supply in a star or triangle way, or to the three-phase power supply through a transducer.

When used in conjunction with a frequency converter, the induction motor becomes a “variable speed drive system”.

Other common terms: squirrel-cage motor.

See → “Dual-shaft Motor Module”

Automatic restart Siemens Controller Supplier

The “Automatic Restart” function can automatically power on the inverter after a power failure and reconnection, without confirming the power failure error.Automatic restart function can reduce the number of drive downtime and production failure.

However, after a prolonged power failure, it may be dangerous to automatically resume switching on the drive without operator operation, and operators must be aware of this.In such a dangerous situation, external control measures should be taken as needed (e.g., cancel the switch on command) to ensure safe operation.

Typical applications for automatic restart function: pump/fan/compressor drives operate as separate drive systems, usually without the need to provide local control options.Automatic restart function cannot be used for continuous material feed and motion control of collaborative drives.

Synchronous motor

Synchronous servo motor and frequency accurate synchronous operation.These motors have no slip (whereas → “asynchronous motors” have a slip).According to its structure type needs different control and regulation scheme, so that it can be operated through the frequency converter.

Synchronous motor has the following characteristics:

The permanent magnet is excited alone

With/without damped rat cage

With and without location encoders

Advantages of synchronous motor:

High dynamic response (→ “synchronous servo motor”)

Strong overload capacity.

High speed accuracy with specified frequency (Siemosyn motor)

Synchronous servomotor  Siemens Controller Supplier

Synchronous servo motor (e.g. 1FK, 1FT) is a permanent magnet equipped with a position encoder (e.g. → “absolute value encoder”) → “synchronous motor”.Due to the small moment of inertia, the dynamic performance of the drive system is good, for example, because there is no power loss, which can achieve high power density and compact structure.Synchronous servo motor can only be used with frequency converter.Since servo control is required for this purpose, the motor current is related to the torque.The instantaneous phase relationship of the motor current can be deduced from the rotor position detected using the position encoder.

A system architecture with a central control module

Each electronic cooperative drive device can work cooperatively in order to complete the user’s driving task.The upper controller enables the drive unit to produce the desired coordinated motion.This requires the controller and all the driver should be between the realization of cyclic data exchange.Until now, this data exchange had to be done through a fieldbus, which was correspondingly expensive to install and design.The SINAMICS S120 variable speed cabinet takes a different approach: a single central controller provides drive control for all connected shafts, with technical logical interconnections between drives and between shafts.Because all the required data is stored in the central controller, there is no need to transfer the data.Cross-axis connections can be made within a controller, and easy configuration can be made using the Starter debugging tool with a mouse.

SINAMICS S120 inverter control cabinet can automatically perform simple technical function tasks

These control units are based on the object-oriented SINAMICS S120 standard firmware, which contains all the most commonly used control modes and can be upgraded to meet the highest performance requirements.

Driver control is provided in the form of conveniently configured driver objects:

Incoming line rectifier control

Vector control

Variable speed drives with high accuracy and torque stability for general purpose machine and factory construction

Especially suitable for asynchronous (induction) motors

The pulse mode is optimized for an efficient motor/frequency converter system

Servo control

Angular synchronization with isochronous PROFIBUS/PROFINET

Can be used in machine tools and production machinery

The most commonly used V/F control modes are stored in vector control drive objects and are suitable for performing simple applications such as group drives using Siemosyn motors.

The CompactFlash card

The functions of the SINAMICS S120 drive are stored on the CF card.This memory card contains firmware and parameter Settings (in item form) for all drivers.The CF card can also save additional items, which means that when debugging different types of series of machine tools, you have immediate access to the right items.After the control unit starts, the data from the CompactFlash memory card is read and loaded into RAM. Siemens Controller Supplier

Firmware is organized as objects.The driver object is used to perform open-loop and closed-loop control functions for the input module, the motor module, the power module, and other system components connected via the Drive-CIQ.
