7.9 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� The
regulation of the heating can be deactivated by writing the value 0 to the object
2014h�
> Reduction of temperature stability
> In the operational state the current consumption drops
7.10 MEMS self-test (4004h)
To check the function of the measurement axes a self-test can be carried out� To
activate the self-test the value 1 is written to the object 0x4004/01h� The self-test
takes about 2 s� After the self-test has been carried out the object 0x4004/01h
contains the value 0�
The test result is coded in a byte and can be read from the object 0x4004/02h
(self-test register)�

00000011: The 2 least significant bits code the internal x, y measurement axes
Bit 0: axis faulty
Bit 1: axis functional
7.11 Temperature of the measuring cell (4080h)
The temperature of the measuring cell is determined every 200 ms and updated in
the object directory� It can be read via SDO access to the object directory (in every
device state) and via TPDO� The signed 32-bit value (two's complement) indicates
the temperature in °C�
7.12 Inclination values longitudinal and lateral (6010h and 6020h)
The current angle values of the inclination axes can be accessed via SDO access
to the object directory (in every device state) and via TPDO� The conversion of the
100-fold, signed 16-bit inclination value (two's complement) is as follows:
Value of 6010h = -2370 / 100 = -23�70°
