8.6.1.2 IQ Historic Torque Displays
These screens show 8 values of torque for the actuator traveling in the opening or closing direction. They are
the values which have been most recently received from the field unit. The 8 values refer to the actuator
motor torque at the following positions of the actuators stroke, 6%, 19%, 31%, 44%, 56%, 69%, 81% and
94%. thus on the "Open Torque" example screen shown above, 101% is the torque value at 6% open, 83% is
the torque value at 19% open, etc.
Torque values are displayed as percent of rated torque and have a range of 0 to 120%.
Note that if the actuator has been moved over part of its stroke, e.g. from 20% to 60% open, then the torque
values outside that range may have been reset to zero.
If the IQ field unit has been programmed with a torque filter factor of “000” then these 8 torque values are
automatically returned to the master station once the actuator has traveled from one end of travel to the other.
However, if the filter factor has been set to a value greater than “000” these values are only returned when the
reload button is pressed. Pressing reload will also cause the master station to fetch the torque values when the
actuator has not traveled from end to end, irrespective of filter factor setting.
Commands available:
