Definitions

  • the invention relates to a method for electronic drive control after The preamble of claim 1. Such a method is e.g. out US-A-5 530 615 is known.
  • EP 0 789 378 A1 is an electronic drive control for a Magnetic drive known.
  • control voltage of a contactor is derived from one of the three phases, it can be sync effects between the closing or opening angle of the Main contacts in the load circuit and the AC control voltage lead.
  • the object of the invention is a method according to the preamble of claim 1 to create, in which the life of a contactor is increased.
  • the invention prevents uneven burning of the switching contacts and thus increases the life of the contactor.
  • Fig. 1 shows a timing diagram in which the rectified in a lower curve Supply voltage is shown, wherein the supply voltage a AC voltage is.
  • a randomly determined delay time t x is provided, which lies between zero and half the period of the control voltage. Only after this delay time, wherein the time is marked with t 3 , the supply voltage is measured, wherein the supply voltage, both a DC and an AC voltage can be. It is checked which supply voltage is concerned (AC or DC). At the same time, the height of the applied voltage is determined. Furthermore, it is checked after t 3 whether the supply voltage is within a predetermined voltage window U min , U max , ie whether the determined value is within the permissible range.
  • the switching point t 5 of the contacts is also distributed randomly for the other phases, which causes a uniform stress on the switching contacts.
  • the undesirable synchronization effect will be explained in more detail with reference to FIG.
  • the dashed lines show different switch-on points, to which different voltage values can be assigned. Since the voltage for starting the microcontroller must first be established, the reset signal is almost always independent of the switch-on time on the same point of the curve, so that the switch-on times are practically synchronized to the same reset time. If the control voltage is switched on, for example, at zero voltage, the supply voltage for the electronics does not build up immediately.
  • Random generator To realize a timer with a variable, randomly set time is Random generator needed.
  • the value provided by the random number generator then becomes edited so that with the subsequent processing of the value a time of Zero to a maximum of half the period of the control voltage results.
  • FIG. 3 shows a schematic diagram.
  • a value is read out in a RAM memory location in the microcontroller, wherein the content of this cell is not defined after power connection.
  • 4 shows the associated flow chart for implementation with a RAM.
  • a value is obtained from a memory cell 1 of an EEPROM, which is manipulated accordingly.
  • the old value is used to determine the new value.
  • the old value is then replaced by the new value in the EEPROM.
  • the manipulated value is written in a register 2.
  • the timer is then started. When the timer reaches zero, a timer underflow will be generated, which will be passed to the CPU, and the program will continue.
  • Fig. 5 shows the corresponding flowchart.
