4.5.16 TrimLimSpdZero_Pct
This is the amount of speed trim the regulator will output at zero speed. This value is
in percent of Maximum Line Speed.
Usage – This value is typically 1 to 2 %. Connect to the Trim Limit at Zero speed
value tag. Or set the constant value in the JSR.
4.5.17 LineSpdTrimLimSpd_Pct
This is the line speed where the trim limit output will be equal to TrimLimSpd_Pct. As
the line speed is increased from zero to this value, the trim limit output is
incrementing from TrimLimSPdZero_Pct to TrimLimSpd_Pct. This value is entered
as a percent of maximum line speed.
Usage – Connect to the Line Speed Maximum for trim reference tag or set the
constant value in the JSR.
4.5.18 TrimLimTrq_Pct
This is the trim limit when the trim regulator is acting in torque control. It is entered
as percent of maximum tension for the section.
Usage – This value is typically 20 to 30%. Connect to the Trim Limit Torque tag or set
the constant value in the JSR.
4.5.19 TrimRate_PctSec
When the trim regulator is turned off, the output is ramped from the current value to
zero. The decrement rate is determined by TrimRate_PctSec. This is part of “bump
less” transfer for the tension control circuit.
Usage - Set this value to avoid sudden changes in tension when the regulator is
switched off. This is used when the system is changed to sensor less mode.
