In order to realize the deceleration to advanced motor, can also be of short duration inactive to it.Obviously, it is also possible that resistors in series is temporarily switched to in the motor line of relevant motor in series.So feasible, make, described resistors in series is during operation by such as relay switch bridge joint, and wherein, this relay switch disconnects and for slowing down.
Regulate routing information can be obtained by the counting of the ripple of the counter electromotive force to the motor be associated.
It is also possible that use Hall element, potentiometer, raster generator.Obviously, it is also possible that limit switch is arranged on ad-hoc location along adjustment path, this limit switch produces routing information or can be used for correction adjustment path values.
As with the first-described, the control device 9,9 ' of electric furniture driver 100,100 ' comprises for detecting the checkout gear driving particular value, drive particular value such as, the motor current, motor operating voltage, velocity of motor etc. of the motor of the adjusting driver 7,7 ', 8,8 ' that at least one is associated, or the control device 9,9 ' of electric furniture driver 100,100 ' is connected to such checkout gear.Alternative driving particular value be adjusting driver 7,7 ', 8,8 ' can the adjustment path of output element of linear displacement or the adjusting angle of the rotation of another adjusting driver or pivotable output element, more detailed description is not carried out to it herein.
Further, a kind of alternative embodiment provides the operating unit 10 of multiple control furniture device 200.The embodiment alternative according to another, at least one adjusting driver 7,7 ', 8,8 ' can comprise control device 9,9 ', wherein, adjusting driver 7,7 ', 8,8 ' and control device 9,9 ' there is shared shell.Reference numerals list
