Inclination sensor JN 7.3.2 Synchronised transmission after reception of a SYNC telegram For the synchronised transmission CANopen provides the SYNC object at which the TPDOs are transmitted after every "nth" reception of a SYNC telegram. Each inclination sensor has several transmit process data objects (TPDOx). The TPDO1 contains the current inclination values (longitudinal and lateral) as 16-bit values.

Inclination sensor JN Pre-defined error field (OD index 1003h) Each inclination sensor has an error list with the 50 most recent errors. The pre- defined error field (OD index 1003h) contains the number of error entries (OD index 1003h/00h). The other sub-indices contain the saved error states in chronological order with the error occurred last being always found under the lowest sub-index (OD index 1003h/01h).

Inclination sensor JN Value range for this option – Inclination value longitudinal (gradient angle): -90°…+90° – Inclination value lateral (angle of direction): 0°…360° Critical point With a gradient angle of 0° the sensor is in a horizontal position. In this position the second angle (angle of direction) is useless.
Inclination sensor JN As a result of this the measured values of the gimbal angle X and the gimbal angle Y are identical as long as the measured object is only rotated about one of the sensor's axes. The measured values of the two options do not differ until a general rotation is made about the two sensitivity axes.
Inclination sensor JN 9.2 Limit frequency digital filter (SDO index 2043h) With the sensor it is possible to make continuously arising angle values insensitive to external interfering vibrations. Using a configurable filter (digital FIR filter) interfering vibrations can be suppressed. The limit frequency of the filter is set via the FIR filter step (SDO index 2043h).
Inclination sensor JN The result of this is that at the teach moment the xs axis must not be parallel to the direction of gravitation. As long as the value for the SDO index 2042h is 1, all angle indications are converted into the new reference system.
Inclination sensor JN For the gimbal angles the roll angle is corrected. Gimbal X: longitudinal x (pitch angle), lateral y (roll angle) Gimbal Y: longitudinal x (roll angle), lateral y (pitch angle) 9.6 Heating (2041h) To ensure good temperature stability over the whole temperature range, the measuring cell is regulated to a constant temperature using a PID controller.
Inclination sensor JN If the vibration measurement is active, the sensor provides two different characteristic values. The first characteristic value (SDO index 5C10h) provides the vibration velocity (v effective [1/10 mm/s]) and the second characteristic value (SDO index 5C11h) the maximum acceleration (a peak [mg]). 10.2 Configure measuring plane (SDO index 2048h) The measurement categories are calculated by default from the measurement axes of the internal acceleration measuring cell as follows:...
Inclination sensor JN 10.3 FIR filter (SDO index 2049h) The sensor provides the possibility to filter the vibration signal. Depending on the application the frequency range to be measured can be adapted. The limit frequency of the filter is set via the FIR filter step (SDO index 2049h). When the FIR filter has been changed for Veff or aPeak, the measured values are only transferred when the filters are in the steady state.
Inclination sensor JN 11.2 Reset the connection set (OD index 1011h) The saved communication profile (OD index 1000h - 1FFFh) can be reset to the factory settings via the entry 1011h/01h by writing the command "load" (64616F6Ch) in this entry. After a "reset application" (NMT command) or a hardware reset the changes become effective.
Inclination sensor JN If the status or toggle bit do not correspond to the response expected from the guarding master or no response is given, the master assumes a slave error. With this mechanism the node to be monitored can detect even the failure of the guarding master.
Inclination sensor JN 12.3 Status LED (to CiA DR-303-3) The integrated LEDs indicate the current device status (Run LED, green) and CAN communication errors (error LED, red).
