Caution
Be sure to install a current-limiting resistor R according to the pulse-train signal voltage.
Without the current-limiting resistor R, an overcurrent may damage the circuit.
3) Pulse-input signal specification
Use a positioning unit that is compatible with the following input signal specification.
