Take the following steps to prevent erroneous operation caused by noise interference:
• Use shielded wire for the PG encoder signal lines.
• Use separate conduit or cable tray dividers to separate option control wiring, main circuit input power wiring, and
motor output power cables.

Terminal Functions
Table 8.8 Option Terminal Functions
Setting the PG Encoder Power Supply Voltage
For the PG-X3 Option, set the voltage for the PG encoder power supply using jumper CN3 located on the option.
NOTICE:
The positioning of jumper CN3 selects the PG encoder power supply voltage (5.5 V or 12 V). Select the voltage level for the
PG encoder connected to the option and motor. If the wrong voltage is selected, the PG encoder may not operate properly or may
become damaged as a result.
