• 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.

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.
