8.2 Timing Specifications

8.2.1 Design Notes for Remote Input Signals

The following charts indicate timing sequences for the primary operations of the
Controller.
The indicated time lapses (time durations) should be referred to only as reference value
since the actual timing values vary depending on the number of Manipulators and the
number of tasks running, as well as CPU speed of the Controller. Check carefully and
refer to the following charts for the timing interrelation when you enter an input signal.
During system design, make sure that you actuate only one remote input operation at a
time, otherwise an error will occur.
The pulse width of an input signal must be 25 or more milliseconds to be detected.
