BRIEF SUMMARY
FIELD OF THE INVENTION
This application is a 371 of PCT/DE97/00452 filed on Mar. 7, 1997.
The present inventions relates to an apparatus for operating a positioning drive.
BACKGROUND INFORMATION
Conventional systems parameterize positioning drives as a function of a previously known load. The parameters of the positioning drive may include specific positions at which the positioning drive is to arrive. Different parameter sets serve to adjust the respective monitoring criteria to the different load situations. Parameterization of the positioning drive occurs, depending on the intended application, prior to assembly.
SUMMARY OF THE INVENTION
An apparatus for operating a positioning drive according to the present invention has the advantage that parameterization of the positioning drive can occur after assembly. A reference run automatically ascertains the application for which the particular positioning drive is provided. The apparatus thereupon automatically selects the appropriate parameter set. The apparatus according to the present invention contributes to a reduction in variants, since now one and the same apparatus can be assembled in different applications. The different parameter sets then cover the various load instances.
The apparatus for operating a positioning drive according to the present invention may be used in positioning drives for power windows and sun roofs.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates an exemplary embodiment of the present invention.
FIG. 2 illustrates a flow chart of an exemplary reference run.
DETAILED DESCRIPTION
A positioning drive 10 moves a part 11 which can be shifted at least between a position 1 and a position 2. A displacement sensor 19 generates displacement signals 20 which, like position signals 17 generated by a position detector 16, are delivered to a displacement determination device 18. Displacement determination device 18 exchanges signals with a control arrangement 12. Displacement determination device 18 makes available to a data set selector 14 signals with which data set selector 14 selects one data set 15 from various data sets stored in a memory 13, and delivers it to control arrangement 12. After receiving the "start reference run" signal 21, control arrangement 12 starts a reference run.
FIG. 2 describes one possibility for carrying out the reference run. Starting from action 0, the idle position, action 1 is initiated after actuation of the "start reference run" signal 21. Position 1 is thereby reached. Once position 1 has been reached, the counter for displacement determination device 18 is started (action 2), and the instruction is given to reach position 2 (action 3). Once position 2 has been reached, in action 4 the counter for displacement determination device 18 is stopped. Then, in action 5, a data set selection 14 is performed for positioning drive 10. After data set selection 14, the end of the reference run has been reached.
The arrangements shown in FIGS. 1 and 2 operate as follows:
The apparatus is in the idle position (action 0); part 11 may be in any position. Memory 13 contains a variety of data sets, none of which have yet been reported to control arrangement 12 as being relevant. The reference run is initiated via the "start reference run" signal 21. The signal could, for example, be generated during the first actuation of positioning drive 10.
During action 1, control arrangement 12 must send control signals to positioning drive 10 in order to reach position 1. It is conceivable in this context for positioning drive 10 to move part 11 at a predefined rotation speed in a predefined direction. For example, assume that positioning drive 10 will first move part 11 to the right as shown in FIG. 1. If the initial position of part 11 is to the right of position 1, part 11 will first reach position 2. Position detector 16 thereupon delivers position signals 17 to displacement determination device 18 and to control arrangement 12, informing control arrangement 12 that position 2 has been reached.
