Indirect tension control
Indirect tension control is an open loop control, since the actual tension is not measured. The tension is controlled via
diameter and pre-set charts for inertia and friction. The speed controller stays active, but is saturated. This structure
provides a very robust control behavior because no physical tension measurement is required. Following parameters are
set when using WinderMacro (61.01) = IndirectTens:
