Preset duty cycle, minimum 100 ms
 At the preset pin, a voltage of at least 4.25 V must be applied to reset the multiturn
count.
 To prevent unintentional resetting, the voltage must not exceed 2 V.

For a battery voltage U
Bat
< 2.8 V the nERROR error bit is set in the BiSS-C protocol,
see chap. 3.5, p. 11.
 As an option, the maximum permissible acceleration can be adjusted at the factory.
The power consumption increases with increasing maximum permissible accelera-
tion.
