FAQ
Q1: Why does this board have a name suggesting both "I/O" and "Rectifier" functions?
A1: This board integrates both functions: it manages low-voltage control signals (I/O) while also containing or interfacing with the rectifier circuitry, which converts AC mains voltage to the DC-link voltage and supplies low-voltage DC power for control electronics.
Q2: What is the primary function of the Analog Input terminal on this board?
A2: The Analog Input (0 V to 10 VDC) typically serves as the speed reference signal, allowing an external potentiometer or PLC output to adjust motor speed steplessly.
