Parameters 1752424 Speed referenceconditioningSpeed error calculation; speed error window controlconfiguration; speed error step.See the control chain diagram on page 448.24.01 Used speed reference Displays the ramped and corrected speed reference(before speed error calculation). See the control chaindiagram on page 448.This parameter is read-only.--30000.00… 30000.00rpmSpeed reference used for speed error calculation. See par.46.0124.02 Used speed feedback Displays the speed feedback used for speed errorcalculation. See the control chain diagram on page 448.This parameter is read-only.--30000.00… 30000.00rpmSpeed feedback used for speed error calculation. See par.46.0124.03 Speed error filtered Displays the filtered speed error. See the control chaindiagram on page 448.This parameter is read-only.--30000.0… 30000.0rpmFiltered speed error. See par.46.0124.04 Speed error inverted Displays the inverted (unfiltered) speed error. See thecontrol chain diagram on page 448.This parameter is read-only.--30000.0… 30000.0rpmInverted speed error. See par.46.0124.11 Speed correction Defines a speed reference correction, ie. a value added tothe existing reference between ramping and limitation.This is useful to trim the speed if necessary, for exampleto adjust draw between sections of a paper machine.See the control chain diagram on page 448.0.00 rpm-10000.00… 10000.00rpmSpeed reference correction. See par.46.0124.12 Speed error filter time Defines the time constant of the speed error low-passfilter.If the used speed reference changes rapidly, the possibleinterferences in the speed measurement can be filteredwith the speed error filter. Reducing the ripple with thisfilter may cause speed controller tuning problems. A longfilter time constant and fast acceleration time contradictone another. A very long filter time results in unstablecontrol.0 ms0…10000 ms Speed error filtering time constant. 0 = filtering disabled. 1 = 1 ms2525 Speed control Speed controller settings.See the control chain diagram on page 452.25.01 Torque referencespeed controlDisplays the speed controller output that is transferred tothe torque controller. See the control chain diagram onpage 452.This parameter is read-only.--1600.0…1600.0% Limited speed controller output torque. See par.46.03No. Name/Value Description DefaultFbEq 16
