Definitions
- the invention relates to a method for the decentralized construction of a device for regulating the precise angular synchronism of individual, variable-speed electric drives of a multi-motor drive system networked by a synchronization bus, the drives being given an angle setpoint of a master pointer.
- the invention also relates to the associated device for the purpose of carrying out this method.
- decentralized synchronous control which are particularly suitable for directly driven, shaftless processing machines in the paper, printing, packaging and textile industries.
- Such a decentralized synchronous control should also be applicable for drives with a relationship and ensure that the individual drives can be freely assigned to different drive groups, while at the same time relieving the higher-level system of time-critical and synchronized tasks.
- the object is achieved in that a separate master pointer is generated in each drive, which is formed decentrally in the respective drive control unit from a speed setpoint supplied to all drives via the synchronization bus.
- the master pointer is preferably generated from the speed setpoint in the form of a sawtooth.
- the leading pointer is advantageously set statically and dynamically to a predetermined angle, the leading pointer being able to be placed on any reference point.
- each individual drive control device is housed.
- the individual drive control devices only require non-time-critical setpoints, which means that no special speed and synchronization requirements are imposed on an existing, higher-level control system.
- Each drive is preferably associated with an individual speed ratio. Such a drive with a relationship is synchronously controlled and maintains its relative position at an angle. Furthermore, each drive can be loaded with an individual offset angle and thus its position can be adjusted.
- the associated device for carrying out the method consists of a superordinate control system which is connected via a synchronization bus to drive control devices which have angle setpoint generators, each drive control device having its own angle setpoint generator as a guide pointer.
- the device is decentralized and can be modular.
- the respective ramp-function generator advantageously enables each individual drive to be synchronized and shut down in parallel by stopping the speed setpoint "zero" and switching to a parameterizable deceleration ramp in the event of a communication fault with the synchronization bus.
- For the speed ratio it is advantageous that it has a fixed value or can be specified by the higher-level control system.
- FIG. 1 shows a system according to the prior art
- FIG. 2 shows a first arrangement according to the invention
- FIG. 3 shows a second arrangement provided with expanded functionalities according to the invention.
- a system that is constructed in principle according to FIG. 1 can be regarded as prior art.
- a device hereinafter referred to as the drive master 7, takes over the time-critical tasks and thus relieves the burden on a generally present, higher-level control system 5.
- the control system 5 supplies the drive master 7 with the machine speed v *.
- This setpoint is fed via a ramp generator 10, which generates the speed reference setpoint n L *.
- the Leitz Eiger generates 12 a the speed reference value n L * L * w corresponding Winkelleitsollwert.
- These two setpoints are sent to the drive control devices for the first drive l ⁇ up to the next but one drive l n .
- the number of connected drives can be up to around 100.
- the drive controls 14 ⁇ - 14 n essentially consist of a synchronous and a torque / current control, whereby a synchronous control is defined in terms of drive technology as a speed control with a superimposed angle control, and run completely in the drive control devices l ⁇ - l n .
- Each synchronous control loop is closed by the feedback of the encoder signals from the high-resolution rotary encoders 20 ⁇ -20 n , which determine the position of the motors 2 ⁇ -2 n .
- the speed of the motor can be calculated by differentiating the position. If high demands are placed on the accuracy, the position of the work machines 3 X - 3 n is also detected with the additional sensors 30 ⁇ - 30 n .
- a prerequisite for the implementation of such a structure is the existence of a bus system between the drive master 7 and drive control devices li-l n , which on the one hand enables fast data throughput, but can also synchronize all participants via an interrupt-controlled, central clock specification.
- a bus system called drive bus in EP 0 567 741 B1
- This synchronization bus 4 ensures that all drives determine their actual angle values at the same point in time and at the same time intervals, ie at equidistant intervals. This time interval corresponds to the time base that applies to the formation of the angle increments. Therefore, the formation of the angle setpoint in the drive master 7 must be calculated in time with the interrupt generation of the synchronization bus 4.
- SIMOLINK ® interfaces are available for the SIMADYN D ® control system on the 40 M drive master side and for the SIMOVERT ® Master Drives family of converter controllers on the 40 ⁇ - 40 n side.
- Time-non-critical setpoints, actual values, parameters, and control and status signals are normally exchanged via a separate control and parameterization bus, which is not shown in FIG. 1.
- a separate control and parameterization bus is described in detail in WO 97 11848 A.
- PROFIBUS DP can be used to implement such communication.
- Automation devices SIMATIC ® S5 / S7 as control system 5 according to Siemens production pattern have corresponding interfaces 60 M or 60 L.
- the functionality of the drive master can also be integrated in the control system.
- the central generation of at least one angle setpoint, and thus a time-critical and synchronized process variable, is characteristic of the systems known to date.
- Such a concept has the disadvantage that the drive master 7 has to be synchronized with the bus clock of the synchronization bus 4.
- the drive master 7 must calculate a current angular reference setpoint w * within each bus cycle. Additional difficulties arise if the angular reference setpoint w * is changed individually for each drive, for example by adding a drive-related angular offset: - Drive master 7 must form the angle setpoints for all drives within the short bus cycle.
- FIGS. 2 and 3 Based on such a known system, the arrangement according to FIGS. 2 and 3 would be further developed. What is common and essential in both arrangements according to FIGS. 2 and 3 is that the angle setpoint value generators 12 are located decentrally as leading pointers in the respective drive control device li to l n . A drive master 7 with ramp generator 10 is also present in FIG. 2, which generates the speed setpoint n * from the machine speed setpoint v *.
- the arrangement according to FIG. 3 relates to a completely decentralized structure which fulfills all the requirements for a synchronously controlled drive in a multi-motor drive system networked by a synchronization bus 4, without placing special requirements on a higher-level control system.
- FIGS. 2 and 3. 1 have the same components and 2 and 3 the same designations, the drive numbering 1 - n being omitted as an index in FIGS. 2 and 3.
- Each decentralized drive control device 1 is now equipped with a ramp generator 10 and a guide pointer 12.
- Each drive is supplied with the machine speed setpoint v * belonging to its machine network via the synchronization bus 4. After the setpoints have been distributed, an interrupt is sent to all drives.
- This synchronization ensures that all participants in a drive system always process their computing cycles with the same, current machine speed setpoint v *. Since digital systems guarantee exactly the same calculation, each drive can determine the speed and angle setpoints for itself.
- the greatest advantage of the structure according to FIGS. 2 and 3 is that no angle setpoints or angle deviations have to be formed in the drive master with each bus cycle.
- the machine speed v * or the speed n * is forwarded directly by the corresponding operating system and does not need to be updated every bus cycle.
- the drive control devices 1 can thus be connected directly to the superordinate control system 5, which is freed from time-critical and synchronized tasks.
- SIMATIC ® S7 has already been implemented.
- the important functionality of the synchronously controlled stopping in the event of a bus fault can be implemented in a simple manner. If communication with the control system 5 fails and the machine speed setpoint v * fails, the ramp-function generator 10 can be charged with the setpoint equal to zero by means of the internal control signal "set ramp generator zero So". At the same time, the ramp-down time of ramp-function generator 10 is switched over to a braking ramp that is parameterized the same for all drives. In this way, the individual drives can be synchronized and thus shut down in parallel.
- the corresponding bus monitoring mechanisms are implemented in the SIMOLINK ® mentioned above.
- a speed ratio r can be implemented in a modular manner, which is additionally implemented in FIG. 3.
- This relation r corresponds to the transmission ratio of a mechanical transmission and can have a fixed value or be specified by the control system 5.
- the relationship value r is multiplied by the speed setpoint n * by means of the multiplier 11.
- each drive with a relationship must be equipped with its own guide pointer 12, which calculates a drive-related angle setpoint w a * from the speed setpoint n r *, which has a relationship. This means that each drive has its own "virtual shaft" as a reference point.
- the control pointer 12 can be statically or dynamically set to a predetermined angle setting value w s by means of the control signal “set angle S w ”. This allows the drive to be positioned or synchronized to any reference point.
- the drive-related setpoint angle w a * can be additionally applied to the offset angle w with an adder 13, in particular in FIG.
- the position of the individual drive can thus be adjusted and the functionality of a register or register adjustment can be realized.
- the offset angle w v can be specified by the host computer 5 or by an external device, such as a register control.
- the setpoint angle value w * resulting from the addition is forwarded to the synchronous control 14 together with the speed setpoint n r * which is subject to relations.
