Adjustment for LPVR-DUO

By default low pass filtering is applied to the LPMS-IG1 gyroscope output. Usually this This improves the quality of the signal especially for applications with slower slow rotations. In case of your faster rotations e.g. in a motion simulator it is probably better recommended to change to the low-pass filter settings for the sensor to become more responsive. Please follow the steps below to tweak the settingsdo this:

  • Save sensor settings file from sensor

    • Open IG1Control

    • Connect to

    • LPMS-IG1

    • Go to menu

    • bar → Settings → Save settings to file

  • In the file

  • you saved, change G1F to 2500 as shown below:

...

  • Save file in the editor

  • In IG1-Control reload the settings file: menu bar → Settings → Load settings from file

  • Save settings to sensor: menu bar → Settings → Save parameters to sensor

...

  • Power cycle. The sensor should now respond faster to orientation changes.

Generally Available Settings

NOTE: These extended settings are usually not required for optimum LPVR-DUO performance.

In the settings file the following lines can be edited to change the filter settings for LPMS-IG1 gyroscope and accelerometer:

Possible accelerometer / gyroscope settings:

  1. Accelerometer settings:

    • AR (accelerometer range, g): 2, 4 (default), 8, 16

    • AOR (accelerometer data output rate, Hz): 3, 7, 15, 31, 62, 100 (

      defaut

      default), 125, 200, 250, 500, 1000

    • AF (accelerometer 3-dB bandwidth, Hz): 5, 10 (default), 21, 45, 99, 218, 420

  2. Gyroscope settings:

    • GR (gyro range, dps): 400 (default), 1000, 2000

  3. Gyroscope I (high precision) settings:

    • G1OR (gyro data output rate, Hz): 100, 200, 400, 800, 1600, 3200, 6400, 12800 (default)

    • G1F (gyro low pass filter): value of G1F is calculated as LpfOrder*1000 + LpfFrequency

      • LpfOrder (low pass filter order): 2, 3, 4 (default)

      • LpfFrequency (low pass filter cutoff frequency, Hz): 10 (default), 35, 45, 50, 70, 85, 100, 140, 175, 200, 285, 345, 400, 500

      • Default value: 4*1000 + 10 = 4010

  4. Gyrosocpe II (High range) settings:

    • G2OR (gyro data output rate, Hz): 3, 7, 15, 31, 62, 100 (default), 125, 200, 250, 500, 1000

    • G2F (gyro 3-db bandwidth, Hz): 5, 10 (default), 20, 41, 92, 176

  5. Save file and reload the settings file to sensor: menu > load settings from file

  6. Save settings to sensor: menu > save parameters to sensor

  7. Power cycle
