Chapter 6. OPERATION
■ Read timing
● SW1 to 8 and 15 to 16 timing
SW1 to 8 and 15 to 16 are read according to the timing in the figure shown below.
(1) When the input changes from OFF to ON, reading starts within less than 0.2
seconds.
(2) When the input changes from ON to OFF, reading starts within less than 0.2
seconds.
● SW9 to 14 and RUN, FAST (READY FAST) timing
Selecting SW9 to 14 program numbers takes less than 0.4 seconds after a change
in input status.
Thus the following timings (1) to r must be observed during RUN operations.
FAST (READY FAST) operations should follow the same timings.
(1) Time from number selection to leading edge of the RUN signal
:0.4 seconds or more
(2) Time from the leading edge of the RUN signal to number selection hold
:0.2 seconds or more
(3) Time from RUN signal OFF to leading edge of RUN signal
:0.2 seconds or more
(4) Time from leading edge of RUN signal to RUN signal ON hold
:0.2 seconds or more
(5) Time from entry of selected number to program number change
:0.4 seconds or less
(6) Time from leading edge of RUN signal to start of RUN signal
:0.4 seconds or less
Handling Precautions
To ensure correct operation, the above read timings should be regarded as
minimum time settings in external switch operations.
