TENS+COMP CALC.
This block, T 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
TENS+COMP
Range: 0 to 549
(TENS+COMP CALC.)
Destination tag.
INERTIA COMP
Range: xxx.xx %
(INERTIA COMP O/P)
Monitor point on the total inertia compensations.
STATIC COMP
Range: -300.00 to 300.00 %
Static friction compensation set-up parameter.
DYNAMIC COMP
Range: -300.00 to 300.00 %
Variable friction compensation set-up parameter.
REWIND
Range: See below
Switches the sign of the friction compensations when the motor changes direction. This should
be done when the line reverses.
0 : DISABLED
1 : ENABLED
FIX. INERTIA COMP
Range: -300.00 to 300.00 %
(FIX.INERTIA COMP)
Fixed inertia compensation set-up parameter.
VAR. INERTIA COMP
Range: -300.00 to 300.00 %
(VAR.INERTIA COMP)
Variable inertia compensation set-up parameter.
ROLL WIDTH/MASS
Range: 0.00 to 100.00 %
Scales the inertia compensations dependant on roll width. 100% is maximum roll width.
LINE SPEED SPT
Range: -105.00 to 105.00 %
Used to calculate the line speed acceleration rate value for the inertia compensations.
FILTER T.C.
Range: 0 to 20000
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.
