Analog Input Terminals (PO, PI, QI, AUI, ACM)
The maximum input voltage of PI, PO, and QI cannot exceed +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:
Transistor outputs (MO1, MO2, MCM)
Make sure to connect the digital outputs to the right polarity.
When connecting a relay to the digital outputs connect a surge absorber across the coil and
check the polarity.
