A-3-4 Pulse Output Start Time
The pulse output start time is the time required from executing a pulse output instruction until pulses are
output externally.
This time depends on the pulse output instruction that is used and operation that is performed.
* The wait time occurs when there is competition with other interrupts. As a guideline, the wait time will be 0 to 3 ms.
The pulse output change response time is the time for any change made by executing an instruction
during pulse output to actually affect the pulse output operation.
*1 The wait time occurs when there is competition with other interrupts. As a guideline, the wait time will be 0 to
3 ms.
*2 When the frequency of pulse output is lower than 250Hz, 1 control cycle will be equal to the time of pulse output.
Example: The change response time of 100Hz pulse output is above 1 control cycle (10ms) and below 2 control
cycles (20ms).
