<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.
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.
