Application p rofiles
The use of application profiles is the best practice for inclination measurement in various applications. Each
profile has a unique combination of parameters that balance the processing between acceleration MEMS and
gyroscope MEMS, to produce the best measurement quality for that application.
Four application profiles are provided that can be configured via CAN object 3004h. As they are intended to
improve the inclination measurement, the profiles are only effective in a function mode where the inclination
outputs are valid (mode 0, 1, 2, 5 and FF). For each profile, two parameters are available for optimisation of the
outputs.

Output Filter
(subindex 06h)
1st order LPF filter for all sensing
axes.
(
Value range: 0d ~ 10 000d (ms)
A longer filter time results in a
smoother reaction on
peaks/accelerations, but also a
slower reaction to physical
movements.
Moving average filter
TPDO1, TPDO2
(subindex 07h, 08h)
Moving average filter for filtering
noise. (
→ 5.3.3 Digital filters)
N value range: 0d
– 10d
A greater N (number of samples)
results in less noise and a smoother
output, but also a slower reaction to
physical movements.
