Parameter Descriptions
DIAMETER
Range: 0.00 to 100.00 %
Calculated diameter from diameter calculator.
MINIMUM DIAMETER
Range: 0.00 to 100.00 %
Min Diameter from diameter calculator.
VARIABLE INERTIA
Range: 0.00 to 100.00 %
The Variable Inertia is the Inertia of reel.
FIXED INERTIA
Range: 0.00 to 100.00 %
This is the inertia of the motor, gearbox and core.
WIDTH
Range: 0.00 to 100.00 %
The width input sets the web width and scales the variable inertia.
REWIND
Range: FALSE / TRUE
Selects between unwind and re-wind. Selected to REWIND when TRUE.
LINE SPD DEMAND
Range: -100.00 to 100.00 %
Line Speed demand is differentiated to calculate the rate of change of speed for inertia
compensation.
RATE CAL
Range: -300.00 to 300.00
Scales differentiated LINE SPD DEMAND
REVERSE
Range: FALSE / TRUE
Sets the direction of the line speed.
DYNAMIC COMP
Range: 0.00 to 300.00 %
The compensation required to drive the winder at full speed.
STATIC COMP
Range: 0.00 to 300.00 %
The compensation required to drive the winder at minimum speed (zero)
MOD REEL SPEED
Range: 0.00 to 300.00 %
Reel speed feedback.
COMPENSATIONS
Range: —.00 %
Total open loop torque compensation.
