Common point for the power supply and the signal

Input signal from Pulse Generator. Input type is selected by FSW2. It

can be 1-phase or 2-phase input. Maximum 500kP/sec (z-phase

function is reserved). If the voltage exceeds 12V, it needs to use TP

type with connecting the external current limiting resistor(R). The

current should be within 5 to 15mA.

The formal of current limiting resistor is:

5mA ≤ Vin − 2V ≤ 15mA
