This figure shows the pin diagram of the FB_Limiter function block:
The FB_Limiter function block is a limiter function block to limit an input signal within a defined range.
The input signal is limited to a defined range based on the i_rMaxOput and i_rMinOput as shown in the transfer function figure below.
If the input exceeds the upper or lower limit, the output is limited to maximum or minimum values respectively.
With reference to the timing diagram below:
oIf the input is within the defined range, the output is equal to input value.
oIf input value exceeds the maximum limit, the output is limited to maximum output value.
oSimilarly, if the input goes below the minimum output value, the output is limited to the minimum output value.
oIf the function block limits the output, then q_xMinLimActv or q_xMaxLimActv is TRUE, based on the type of limit.
The q_xEn is TRUE as long as i_xEn is TRUE, regardless of detected error.
This figure shows the transfer function of the FB_Limiter function block:
This figure shows the timing diagram of the FB_Limiter function block:
An invalid parameter at the function block inputs results in detected error, and a corresponding detected error ID will be generated.
During a detected error state, the output will be set to zero.
Detected error can be reset only through the rising edge of i_xErrRst input. The output q_xBusy is TRUE whenever the function block is enabled and there is no detected error.
