The counter returns to the initial state, and the reset time is 0.5 seconds. 3. The maximum speed of the calculator is the maximum speed when the duty ratio is 1:1, and the pulse width of on or off is greater than 50 milliseconds. 4. In the control system, the counter control line should be wired separately from other power lines; in a strong current environment with long counting terminal wires, use a shielded wire.
