Data Sheet
In addition to the speed signal, the following information is provided by varying the length
of the output pulses in Figure 3 (PWM modulation):
Airgap Warning range = Warning
Warning information is issued in the output pulse length when the magnetic field is below
a critical value (e. g. the airgap between the Hall Effect IC and the target wheel exceeds
a critical value). The device works with reduced functionality. Warning information is
given only in calibrated mode.
Assembly position range = EL
EL information is issued in the output pulse length when the magnetic field is below a
predefined value (the airgap between the Hall Effect IC and the target wheel exceeds a
predefined value). The device works with full functionality.
Direction of rotation right = DR-R
DR-R information is issued in the output pulse length when the target wheel in front of
the Hall Effect IC moves from the pin GND to the pin
Direction of rotation left = DR-L
DR-L information is issued in the output pulse length when the target wheel in front of
the Hall Effect IC moves from the pin
direction information will be corrected already during uncalibrated mode after 2 pulses.
