17.1.137.2 Function at input value with sign reversal
Selection: C01150 = "2: Loading with level + reset"
[17-64] Switching performance if the input signal changes signs
If "2: Loading with level + reset" is selected in C01150, the bLoad input is status-controlled: In
case of a TRUE signal, the integrator is loaded with the value at dnSet_p and the bStatus output
is set to FALSE.
A positive signal at nIn_v is incremented (the counter content is increased with every function
call).
A negative signal at nIn_v is decremented (the counter content is reduced with every function
call).
dnOut_p outputs the counter content of the bipolar integrator.
If the positive counter content is higher than the comparison value set in C01151/x
, the
comparison value will be subtracted from the counter content, and bStatus will be set to
TRUE for one task cycle.
If the negative counter content is lower than the comparison value set in C01151/x
, the
comparison value will be added to the counter content, and bStatus will be set to TRUE for
one task cycle.
