dnPosIn12_p
provides the counter content of the bipolar integrator.
– If the counter content exceeds a value of +32767 encoder revolutions (corresponds
to +2147483647 incr.), an overflow occurs and the counting process continues at a
value of -32768 encoder revolutions.
– If the counter content falls below a value of -32768 encoder revolutions (corresponds
to -2147483648 incr.), an overflow occurs and the counting process starts at a value
of +32767 encoder revolutions.
bPosIn12_State
is set to TRUE if the comparison value set in
C02845
has been reached.
Function at input value with sign reversal
Selection:
C02844/1
= "2: Loading with level + reset"
[6-3]
Switching performance if the input signal changes signs
If "2: Loading with level + reset" is selected in
C02844/1
, the
bPosIn12_Load
input is
status-controlled: In case of a TRUE signal, the integrator is loaded with the value at
dnPosIn12_Set_p
and the
bPosIn12_State
output is set to FALSE.
A positive
nFreqIn12_v
signal is incremented (the counter content is increased with
every cycle).
A negative
nFreqIn12_v
signal is decremented (the counter content is reduced with
every cycle).
dnPosIn12_p
provides the counter content of the bipolar integrator.
– If the positive counter content is higher than the comparison value set in
C02845
, the
comparison value will be subtracted from the counter content, and
bPosIn12_State
will be set to TRUE for one task cycle.
– If the negative counter content is lower than the comparison value set in
C02845
, the
comparison value will be added to the counter content, and
bPosIn12_State
will be
set to TRUE for one task cycle.
