3.1 General Process FBs
Processing details
When the operation signal (INVLD) is FALSE, this function block performs lead-lag compensation
to the input (IN) and outputs (OUT_) the result.
Processing details
When the operation signal (INVLD) is FALSE, this function block performs integral operation to the
input (IN) and outputs (OUT_) the result.
Processing details
When the operation signal (INVLD) is FALSE, this function block performs derivative operation to
the input (IN) and outputs (OUT_) the result.
Processing details
When the operation signal (INVLD) is FALSE, this function block outputs (OUT_) the result with a
delay by the dead time to the input (IN).
Processing details
Applies high/low limiters with hysteresis to the input (IN) and outputs (OUT_) the result.
Processing details
Limits the variation speed to the input (IN) and outputs (OUT_) the result.
Processing details
Limits the output variation speed to the input (IN) and outputs (OUT_) the result.
Processing details
Sets a dead band to the input (IN) and outputs (OUT_) the result.
Processing details
Changes the output (OUT_) from the output control value CTRLV to the output setting value SETV
smoothly when the mode (MODE) is changed from FALSE (MANUAL) to TRUE (AUTO).
Processing details
Increases or decreases the output (OUT_) at a fixed rate.
Processing details
Performs output ON time conversion for input values and outputs the result in bits. This function
block also adjusts the phase of output cycles automatically to suppress overlapping of output (for
example, peak current).
