VFD500 has two inbuilt counters:Counter 1 is a 32-bit multifunction counter with electronic gears; counter 2
is a 16-bit normal counter with no electronic gear function. Now take the counter 1 as an example to briefly
explain its function and use, and the counter 2 will not be specified.
The counter 1 receives the pulse signal through the terminal corresponding to the DI function "Counter 1
input", and the pulse signal is used for the counter 1 counting after passing through the electronic gear. When
the count value reaches the set value (P45.04), the DO function "Counter 1 set value reached" is valid; when the
count value reaches the maximum value (P45.06), select whether to stop counting or reset the count according
to P45.13. value.
The counter can also be reset by the DI terminal. When the DI Terminal is the "Counter 1 reset" function and
the terminal is valid, the counter 1 is reset.
For example: P45.04=3, P45.08=3, P45.09=1, the function of counter 1 is as shown below.

By setting a reasonable electronic gear, the counter 1 can realize functions such as fixed length in addition
to the counting function, and the user can flexibly use it in specific applications.
