TENS+COMP CALC.
This block, Tension + Compensation
Calculator, compensates for static and
dynamic friction, as well as the load inertia.
It achieves this by profiling the motor
torque demand as a function of speed and
acceleration.
Parameter Descriptions
STATIC COMP
Static friction compensation set-up parameter.
DYNAMIC COMP
Variable friction compensation set-up parameter.
REWIND
Switches the sign of the friction compensations when the motor changes direction. This should
be done when the line reverses.
FIX. INERTIA COMP
Fixed inertia compensation set-up parameter.
VAR. INERTIA COMP
Variable inertia compensation set-up parameter.
ROLL WIDTH/MASS
Scales the inertia compensations dependant on roll width. 100% is maximum roll width.
LINE SPEED SPT
Used to calculate the line speed acceleration rate value for the inertia compensations.
FILTER T.C.
The line speed acceleration rate value is calculated from the line speed input. The calculated rate
value may have a large ripple content which will disturb the motor torque. The rate signal is
therefore filtered, and this filter has a time constant given by this parameter.
RATE CAL
Scales the inertia compensation acceleration rate value to 100% for the maximum line ramp rate.
This parameter should be set to the maximum line full speed ramp rate in Seconds. The resultant
rate value can be observed on the NORMALISED dv/dt value.
Note - Inertia compensation does not work well for line ramp rates above 100 secs and therefore
this parameter is limited to 100.00.
