Definitions
- the invention relates to a method for modernizing a technical system, in particular a production system, according to the preamble of claim 1 and a drive device suitable for this, according to claim 14.
- the system can be modernized by replacing the drive and automation systems, for example those with outdated analog technology, by modern systems in digital technology.
- the system is divided into several sections, which are then modernized step by step.
- Each of these sections e.g. a multi-motor unit together with the power parts feeding the motors (e.g. rectifier, converter or inverter), drive control and possibly higher-level automation can then be planned and modernized separately according to the existing budget.
- the motors e.g. rectifier, converter or inverter
- this object is achieved by a method according to claim 1;
- a drive device suitable for this is the subject of patent claim 14.
- a production plant with such a drive device is the subject of patent claim 17.
- Advantageous embodiments of the method according to patent claim 1 are the subject of subclaims 2 to 13; advantageous embodiments of the drive device according to claim 14 are the subject of dependent claims 15 to 16.
- the invention is based on the consideration that an economically and technically favorable modernization of the technical system is possible in that instead of Conventional "vertical" segmentation of the system into several sections and its step-by-step modernization, eg the replacement of a complete drive device including the cost-intensive power section and the motors, a "horizontal" cut is carried out at the level of the torque setpoint of the individual drives.
- This interface is usually a standard interface, and it is usually possible without major problems to have the torque setpoint specified by another, new speed controller instead of the previous speed controller of the drive motor.
- this speed controller is located in a standard drive component which, in addition to the speed controller, also has a torque controller and a power unit.
- standard drive components are available in a wide variety of performance classes and, thanks to their standardized design, can be inexpensively manufactured and procured in large quantities.
- modern standard drive components enable the connection of the drive device to a modern, higher-level automation system, which provides technological functions such as machine control, setpoint control, technological controls, etc. with the associated operating and monitoring functions (HMI - Human Machine Interface) and thus enable the desired productivity improvements, availability, etc.
- the cost-intensive drive components such as the power section and the motor are not yet being replaced by new components, so that the conversion can be carried out at relatively low costs.
- the drive control and automation level of the system can thus be inexpensively upgraded to a technical and technological level that corresponds to that of a modern, new system in a single conversion step in which all components essential for production are renewed.
- the horizontal cut at the level of the torque setpoint means that there are no complex interfaces between new and old system parts. In this way, the effort for interface adaptations can be kept low and technically less complex solutions that meet the functional requirements of modern systems and are therefore advantageous from a technical point of view can be implemented.
- the speed controller of the standard drive component receives at least one speed setpoint from an automation system and is therefore integrated into a system automation.
- the standard drive component can also input and Receive switch-off commands from the higher-level automation system and report fault and diagnostic messages to the automation system.
- the subsequent step can be made cost-effective in particular if the additional power section is adapted to the standard drive component and replaces the power section of the standard drive component in the standard drive component.
- the further power section is part of a further standard drive component.
- the further power section is part of a further standard drive component.
- a great deal of effort for parameterizing the drive control can be avoided by adapting the further standard drive component to the speed controller and the torque controller of the standard drive component, and the speed controller and the torque controller from the standard. dard drive component removed and integrated into the further standard drive component.
- the existing speed controller or torque controller parameterized for the control can thus continue to be used and a renewed parameterization of the control can be largely avoided.
- the previously used (modern) power section and the remaining part of the standard drive component are no longer required.
- parameterization effort can also be avoided if the parameterization software of the speed controller and torque controller of the standard drive component can be loaded into the corresponding components of the further standard drive component.
- the torque controller of the drive motor is replaced by a further torque controller and the power section is replaced by a further power section, the further torque controller receiving a torque setpoint from the speed controller of the standard drive component ,
- 1 shows a previous (old) drive device of a technical system
- 2 shows a standard drive component
- 3 shows a drive device with a
- the drive device 1 shows a previous (old) drive device 1 of a technical system, for example a production system for paper manufacture.
- the drive device 1 has a drive motor 6, a power section 5 feeding the motor 6 via a feed connection 5a, a torque controller 4 regulating the power section 5 via a control connection 4a and a speed controller 3 which specifies a torque setpoint Msetpoint with respect to the engine torque to the torque controller 4 , A speed actual value ni st required for the control is detected by a speed sensor 7 on the motor 6 and made available to the speed controller 3 and the power unit 5.
- the (old) drive automation 2 is superior to the drive device 1 and specifies a speed setpoint nset to the speed controller 3.
- Both the drive device 1 and the higher-level automation 2 are essentially implemented in analog technology or in outdated digital technology and the drive motor 6 is also implemented in outdated direct current technology, so that the requirements regarding productivity, availability and manufacturing quality of the system are no longer met.
- the modernization Drive component 17 shows a modern standard used in the context of the invention in the modernization Drive component 17, which has at least one speed controller 13, a torque controller 14 and a power unit 15.
- Such standard drive components are available from the applicant in various performance classes with regard to the power section, for example under the product name SIMOVERT MASTERDRIVE.
- SIMOVERT MASTERDRIVE By using standardized components, in particular also standardized speed controllers, torque controllers and power units, in these components, these can be produced and procured cost-effectively.
- the standard drive component is designed in digital technology, advantageously using the latest technology.
- the specification of the torque setpoint M so n for the torque controller 4 is deactivated by the speed controller 3 and a standard drive component 17 according to FIG. 2 is provided.
- the torque setpoint M so ⁇ for the torque controller 4 of the drive motor 6 is then specified by the speed controller 13 of the standard drive component 17.
- the drive device 1 thus has a drive motor 6 fed by the power section 5 and a torque controller 4 controlling the power section 5, whereby an output of the speed controller 13 of the standard drive component 17 is coupled to an input of the torque controller 4 of the power section 5 of the drive motor 6 for supplying the torque setpoint M so n.
- the torque controller 14 and the power section 15 of the standard drive component 17 are not required; The power section 15 can therefore be dimensioned very small with regard to its output power.
- the standard drive component 17 is advantageously coupled to an automation system 12 for supplying at least one speed setpoint (M so u) and is controlled and monitored by the latter.
- the coupling is advantageously carried out by a bus system, in particular a Profibus.
- the speed controller 13 of the standard drive component 17 receives a speed setpoint from the automation system 12 and, if necessary, further switch-on and switch-off commands.
- the standard drive component 17 reports fault messages, diagnostic data etc. to the automation system 12 (not shown).
- the (old) torque controller 4, power section 5 and drive motor 6 used up to now will continue to be used. They can be modernized at a later date without much effort.
- the old automation system in the system can be completely replaced by a new, modern automation system, it being possible to connect all drive devices to the new automation system. Since the modernization of the cost-intensive power units and drive motors will be dispensed with for the time being, and not least due to the use of inexpensive standard drive components, the plant can be modernized cost-effectively.
- the power section 5 of the previous (old) drive motor 6 can be replaced by a further power section 25, the further power section 25 being adapted to the torque controller 14 of the standard drive component 17 and by this a control connection 14a is regulated.
- the further power section 25 is adapted to the standard drive component 17 and replaces the previous power section 15 of the standard drive component 17 in the standard drive component 17.
- the output section 15 of the standard drive component 17 is dimensioned smaller in terms of its output power than the additional power tion part 25, so that its replacement is not particularly important from a cost perspective.
- the torque controller 14 receives a torque setpoint Msoll from the speed controller 13 of the standard drive component 17.
- the previous (old) torque controller 4 and the previous (old) power section 5 are therefore no longer required.
- the drive motor 6 can also be replaced by a modern drive motor 16, for example a low-maintenance asynchronous motor, and can be supplied with current by the power section 25 via feed lines 25a. Due to the close interaction between the drive motor and the power section, it is possible to modernize these two components at the same time.
- the modernized drive motor 16 is then fed via the feed connection 25b.
- the power section 25 is adapted both in terms of its output power and its technology to the respective drive motor 6 or 16 to be supplied with current.
- the further power section 25 can also be part of a further standard drive component 47.
- the further standard drive component 47 is adapted to the speed controller 13 and torque controller 14 of the standard drive component 17.
- the speed controller 13 and torque controller 14 are removed from the standard drive component 17 and integrated into the further standard drive component 47.
- the previous standard drive component 17 with the small-sized power section 15 is then no longer required.
- a simultaneous replacement of the drive motor 6 by a modern drive motor 16 also offers itself here.
- the torque controller 4 of the drive motor 6 is replaced by a further, modern torque controller 34 and the power section 5 of the drive motor replaced by a further, modern power section 35.
- the further torque controller 34 here receives a torque setpoint Msoll from the speed controller 13 of the standard drive component 17 and regulates the reading section 35 via a control connection 34a, which in turn controls the old drive motor 6 or via a feed connection 35a a feed connection 35b feeds the modern drive motor 16 with electricity.
- the old torque controller 4 and the old power section 5 of the drive device 1 are then no longer required, the same applies to the torque controller 14 and the power section
