Chapter 5 Function code
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.
