Set Input Signals For Mfai Terminals A1 To A3 - YASKAWA GA80U4720ABM Manual

A - Load Impedance
• Use in sinking mode
The external power supply changes the voltage level of the pulse train output signal. Keep the voltage from an
external source between 10.8 Vdc to 16.5 Vdc. Adjust the load impedance to keep the current at 16 mA or lower.
External Power Supply (V)
10.8 Vdc to 16.5 Vdc
