In summary and in other words, the invention thus provides, inter alia, a method for multiturn sensor commissioning and calibration by removing an anti-twist device. A multi-turn sensor can be adjusted / calibrated. A multi-turn sensor information can be set to a path axis to be measured.

A procedure may refer to a (path) measuring system which includes a 360 ° magnetic angle sensor capable of detecting a B-field in its magnitude in all three spatial directions. In addition, there may be a multi-turn sensor which is capable of outputting entire revolutions of the path axis by means of a GMR effect due to magnetic domain transitions, this information also remaining after a supply voltage loss. Both sensors can detect an angular position of a sensor magnet by an orientation of its B-field to these sensors. An apparatus to which the displacement sensor is applied may consist of a circuit board containing the sensors and a mechanical part whose spindle revolution or stroke information is to be detected. In an initial merge of both Modules should be matched once the sensor on a way information of a mechanics. The path axis should be smaller than a coverage area of the sensor, so that it can not come to adjustment operations between sensor and distance (total rotation angle) of the mechanism during operation. This would be the case if the overall detection angle of the multi-turn sensor is overrun, so that, depending on how many revolutions the sensor is driven in a direction of rotation, with a subsequent reversal of the direction of rotation of the point from the reversal would be interpreted as a new zero, so that a Original calibration of the path axis would be adjusted. This would result in adjusting the operation of the apparatus, which are interpreted by the sensor with respect to a total stroke wrong (too small or too large stroke than actually present). The aim of the procedure may be to connect the sensor information (number of revolutions) to a previously unknown calibration point.

• – Ein vorrichtungsgebundener Sensoreinstellmagnet bekannter Magnetstärke kann gegen ein definiertes, einer Auslegung entsprechendes bekanntes Axialmaß an beide Sensoren herangestellt werden.
• – Der Sensor kann in eine Richtung verdreht werden, um eine Verdrehungszahl, die größer als ein Gesamtverdrehwinkelerfassungsbereich des Multiturn-Sensors ist.
• – Die Drehrichtung kann umgekehrt und es kann auf eine bestimmte Anzahl von Umdrehungen gefahren werden.
• – Während dieses Einstellvorgangs kann eine Magnetfeldstärkeninformation des Drehwinkel-Sensors und/oder des Multiturn-Sensors ausgelesen und abgespeichert werden.
• – Der Magnet kann von dem Sensor axial weg gefahren werden, wobei die Magnetfeldorientierung entsprechend des zuletzt eingestellten Winkels notiert/erfasst werden kann.
• – Der Sensor kann nun an eine Mechanik gebaut werden. Hierbei kann beachtet werden, dass der Drehwinkel des Sensormagneten dem des ursprünglichen Einstellsensors entspricht.
• – der Sensormagnet und ein Lineartrieb können so angeordnet sein, dass ein Außenring mit dem Sensormagneten starr gekoppelt ist. Bei einem Verdrehen des Außenrings des Lineargetriebes kann eine Spindelachse entsprechend verdrehgesichert werden, damit ein Verstellen einer Wegachse bewirkt werden kann.
• – Um zu vermeiden dass sich der Sensormagnet bei dieser Verstellbewegung mitdreht kann ebenso der Außenring arretiert werden und stattdessen die Spindel verdreht werden.
• – Hierfür kann eine Verdrehsicherung der Spindel für den Einstellvorgang entfernt werden, sodass die Spindel statt des Außenringes für den Verstellvorgang verdreht werden kann.
• – Der Deckel der Elektronikeinheit kann hierfür zweiteilig ausgeführt sein, sodass die Verdrehsicherung auch nach Inbetriebnahme einer Elektronik noch gefügt werden kann.
• – Der Sensormagnet kann dadurch in seiner Ursprungslage fixiert und der Hub abgeglichen werden.
• – Nach dem Einstellvorgang kann dann die Verdrehsicherung der Spindel wieder eingebracht werden.

According to a variant for the adjustment of a path axis to a sensor revolution count, the sensor and the mechanism can be calibrated / configured as follows:

• - A device-bound Sensoreinstellmagnet known magnet strength can be set against a defined, a design corresponding known axial dimension of both sensors.
• The sensor can be rotated in one direction by a twist number greater than a total twist angle detection range of the multi-turn sensor.
• - The direction of rotation can be reversed and it can be driven to a certain number of revolutions.
• - During this adjustment process, a magnetic field strength information of the rotation angle sensor and / or the multi-turn sensor can be read out and stored.
• - The magnet can be moved axially away from the sensor, the magnetic field orientation can be noted / recorded according to the last set angle.
• - The sensor can now be built on a mechanic. It can be noted here that the angle of rotation of the sensor magnet corresponds to that of the original setting sensor.
• - The sensor magnet and a linear drive can be arranged so that an outer ring is rigidly coupled to the sensor magnet. Upon rotation of the outer ring of the linear gear, a spindle axis can be secured against rotation, so that an adjustment of a path axis can be effected.
• - To avoid that the sensor magnet rotates with this adjustment, the outer ring can be locked and instead the spindle can be rotated.
• - For this purpose, a rotation of the spindle for the adjustment can be removed, so that the spindle can be rotated instead of the outer ring for the adjustment.
• - The cover of the electronics unit can be made in two parts, so that the rotation even after commissioning of an electronics can still be joined.
• - The sensor magnet can be fixed in its original position and the hub can be adjusted.
• - After adjustment, the anti-rotation of the spindle can then be reinstated.

• – Die Position der Spindel kann auf einen definierten axialen Wert voreingestellt gefügt werden und der Multiturnsensor kann erst danach auf den entsprechenden Zählwert abgeglichen werden.
• – Hierzu kann auch wieder die Verdrehsicherung der Spindel entfernt werden, dann jedoch der Außenring solange in eine Richtung verdreht werden, bis der Multiturnsensor über seinen Erfassungsbereich hinaus angesteuert wird. Danach kann durch Verdrehen in die andere Richtung der Zählwert des Multiturnsensors auf den zuvor eingestellten Wert an der Spindelachse eingestellt werden.
• – Die axiale Position der Spindelachse kann bei dieser Methode unverändert bleiben, da die Spindel selbst nicht verdreharretiert sein kann, sodass auch kein Hub gefahren wird. Außenring und Spindel können sich als starre Einheit drehen, da der Reibwert zwischen Spindel und Außenring groß genug sein kann, um eine Verstellung der Spindel in axialer Lage zu verhindern. Alternativ könnte der Käfig blockiert werden.
• – Nachdem der Multiturnsensor abgeglichen ist, kann dann die Verdrehsicherung wieder gefügt werden.

According to a variant for the adjustment of a path axis to a sensor revolution count, the sensor and the mechanism can be calibrated / configured as follows:

• - The position of the spindle can be preset to a defined axial value and the multi-turn sensor can only then be adjusted to the corresponding count value.
• - For this purpose, the rotation of the spindle can be removed again, but then the outer ring as long as to be rotated in one direction until the multi-turn sensor is driven beyond its detection range. Thereafter, by rotating in the other direction, the count value of the multi-turn sensor can be set to the previously set value on the spindle axis.
• - The axial position of the spindle axis can remain unchanged in this method, since the spindle itself can not be drehreharretiert, so that no hub is driven. Outer ring and spindle can rotate as a rigid unit, since the coefficient of friction between the spindle and outer ring can be large enough to prevent an adjustment of the spindle in an axial position. Alternatively, the cage could be blocked.
• - After the multi-turn sensor has been adjusted, the anti-twist device can then be re-joined.

With the invention, an adjusted fastening of a magnetic sensor device to an actuator is made possible. Commissioning is possible. Initial assembly of a magnetic sensor device and an actuator is enabled. A matching of a magnetic sensor device to a path information of a mechanism is made possible. Referencing a sensor signal on a linear axis is made possible. Unintentional adjustment during operation is prevented. A misinterpretation of an actuator movement is prevented. A perfect determination of a rotation angle and a perfect revolution count are guaranteed.
