Parameter
Function at constant input value
Selection:
C02844/1 = "0: Loading with level" or "1: Loading with edge"
[7-2] Switching performance if the overflow is in the positive direction
• If "0: Loading with level" 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.
• If "1: Loading with edge" is selected in C02844/1 , the bPosIn12_Load input is edge-controlled: In
case of a FALSE/TRUE edge, the integrator is loaded with the value at dnPosIn12_Set_p and then
immediately continues to integrate, 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).
Parameter Possible settings Info
C02844/1 Function
0 Loading with level Load integrator with TRUE level at
the bPosIn12_Load input (Lenze
setting).
1 Loading with edge Load integrator with FALSE/TRUE
edge at the bPosIn12_Load input.
2 Loading with level + reset Load integrator when reaching the
comparison value or with TRUE level
at the bPosIn12_Load input.
