OPERATING MODES

When writing the number of output pulse (target value)

from a host, R8-PC4A outputs the difference from the

number of pulse outputs until now (present value) as the

remainder number of pulse.

The present value of the R8-PC4A is held even with power

off. If target value is ‘0’ or higher than totalized pulse upper

limit, it is invalid. When the target value is not less than

2001 for the present value, the unit does not output the

pulse and the present value is equal to the target value.

E.g.1 Present value = 1000 and target value = 1500, it

outputs 500 pulses.

E.g.2 Present value = 9000 and target value = 500, it

outputs 1500 pulses.

E.g.3 Present value = 1000 and target value = 3001, it

does not outputs any pulse, present value = 3001.

(When the totalized pulse upper limit is initial setting,

10000.)
