Analog Input Terminals (PO, PI, QI, AUI, ACM)
;
The maximum input voltage of PI, PO, and QI cannot 12V and no more than +/-12V
for AUI. Otherwise, the analog input function may become ineffective.
;
Analog input signals are easily affected by external noise. Use shielded wiring and keep it as
short as possible (<20m) with proper grounding. If the noise is inductive, connecting the shield
to terminal ACM can bring improvement.
;
The interference generated by the Hybrid Servo Controller can cause the pressure sensor to
malfunction. IN this case, a capacitor and a ferrite core can be connected to the pressure
sensor side, as shown in the figure below:
