Screen Function
Definition
Accel time ___sec
Enter a value for the amount of time in seconds that it
takes to accelerate the machine from stopped to
maximum operating speed
Adjust contrast
Adjust the display appearance by pressing 4 to increase
contrast or 9 to reduce contrast
Analog I/O: (sensor type, isolated out…)
Select to configure load cell input and control output
modes
Auto / Manual
Toggles between Manual and Automatic modes; see
also RUN, HOLD, MANUAL, STOP, START, and
SPLICE
Auto tune menu
Select to access the auto tune options
Auto tune start / stop
Toggle to begin or end auto tune feature. CYGNUS will

parameters to correct it.
Bar graph rate
Enter a value for the rate in seconds that the bar graph
display updates. Default value = 0.1 sec.
Basic

Section 6.3
Calibrate
Select to enter sensor and system calibration options.
Calibrate Dynamics
Select to enter tuning parameter calibration options
including out of round roll compensation, gain
scheduling, and dynamic tuning
Calibrate inertia/accel comp
Display directs the operator to calibrate the present
diameter (entered by the operator) with the current
output to the torque device. This step is critical.
Calibrate isolated output
Select to enter control output calibration menu. Use a
multimeter to set the high and low ends of the control
signal output as appropriate for your equipment. (not
normally required.)
Calibrate non isolated output
Select to calibrate inverse diameter output. See also
Section 8.9
