■Trigger current value per cycle change
Uses MCv_ChangeCycleTriggered.
Changes the current value per cycle of the specified operation profile data control FB to the value which is compensated at
the detection timing of the trigger input signal.
Executes current value per cycle change when the trigger signal is detected after the rising edge detection of Execute.
When TriggerInput.Signal.CompensationTime is a positive value, it is executed immediately.
When TriggerInput.Signal.CompensationTime is a negative value, this FB waits for operation to start until the correction time
has elapsed, and it is executed.
ProfileCalc.InputsPerCycle is estimated and changed so that the position will be a position set in Cycle at Trigger signal
detection timing.
Ex.
Operation example by Trigger input signal
When setting Cycle = 100.0 during ProfileCalc operation, and executing current value per cycle change.
