Place a checkmark in the check box to activate offset tracking.
Note
With safety function Speed + Direction or Direction of rotation Offset tracking cannot be
used.
Offset tracking serves the adaptation of the trigger thresholds depending on changes of
the DC signal component caused by radial shaft displacements, for example.
shows the principle of the offset tracking. Until point X, the trigger thresholds are within
the range of the input signal. At point X, the DC component of the input signal rises to the
level marked with C. The signal leaves the range of the trigger thresholds B. At that very
moment, a detection of input pulses is not possible anymore. With activated offset
tracking the trigger thresholds are correspondingly adapted to the change of the input
signal D.

Sensor switch
Place a checkmark in the box to activate the sensor switchover. This parameter is assigned
to safety functions Direction of rotation and Speed + Direction with Pulse wheel selected
for Type of measurement (pulse shape). These safety functions use two channels of the
AMS 6300 SIS for detecting the rotational direction. If a sensor fault occurs at one
measurement channel with activated sensor switchover, the remaining third sensor is
switched to this measurement (see
102
Detection of rotational
direction).
