 Input function command 16: COUNT 1 (counter), Input function command 17: COUNT 2 (counter)
COUNT1 and COUNT2 commands make the inverter count the number of times the input signal
is turned on and off, as shown in the figure below, and put out a signal when reaching the
specified count. The count is reset to zero using the signal specified with the input function
parameter which pairs off with the count command parameter. Note that this command has no
relation to the SET and RESET commands described later.
Counter reset signal
Specify the counter reset signal using the input function
parameter which pairs off with the counter 1 command
setting parameter.

Specified count
Note 1: Specify a pulse width of at least 5 ms for both ON and OFF pulse input signals.
Note 2: RESET commands have priority over COUNT commands. Therefore, if a reset
command is entered instantly the specified count has been reached, the count is reset to
zero and no signal is put out.
Note 3: This command cannot be used in plural. Even if do so, that will not result in an intended
operation.
<Example> Input count signal from Terminal S1 and input reset signal from Terminal S2.
Ouput the signal from Terminal RY-RC with the count of 10.
