16.1.39.4 Evaluation of the output signal
After the limitation, the output signal is evaluated with the influencing factor
nInfluence_a. The evaluation is activated/suppressed along a ramp when the
bEnableInfluenceRamp input is set to TRUE. The ramp times are set with the parameters
"Influence acceleration time" (C00243
) and "Influence deceleration time" (C00244).
16.1.39.5 Comparison function "Actual value = setpoint"
If setpoint and actual value are identical and there is no system deviation, the bSetEqAct
status output is set to TRUE.
The hysteresis of the comparison function has a fixed value of 1 %.
From version 06.00.00, the symmetrical window around the setpoint for the
comparison function can be set in C00247
(Lenze setting: 2 %).
