6.5 Thresholding Page (moncon.htm)
On the Thresholding page, a user can set up to 16 threshold conditions. Threshold conditions compare the
sensor readings to simple user-defined threshold statements. After a user enables threshold monitoring and a
sample is read, a user-defined output code for all threshold conditions satisfied by that sample are compared
with a bitwise OR function or AND function (as defined by a user) to form the threshold output. In practice,
it is very unlikely that more than one threshold sample is satisfied in a single sample. If the threshold
conditions are exceeded, the threshold monitoring latch is set, and threshold monitoring is paused until a
user issues a reset command or a user defined momentary time delay has passed.
Each threshold condition can be configured for the:
•
Axis to monitor
•
Type of comparison to perform
•
Threshold value to use for the comparison
•
Output code to send when the comparison is true

A user may select a calibration range to be applied to the force and torque readings.
For more information about the calibration ranges, refer to the applicable sensor
manual in Table 2.1.
A user may select the sampling frequency for low-pass filtering.
For more information about the sampling rate options, refer to
Section 5.3—Sample Rate.
Filter value disables the low-pass filtering feature. For more information about the
filtering values, refer to
Section 5.4—Low-Pass
A user may enter values for the bias offset applied to the sensor strain gage
readings. To remove the bias offset, set the fields to all zeros.
Note that the strain gage readings do not have a 1:1 correspondence to force and
torque readings.
