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.
Table 8.9 Setting the PG Encoder Power Supply Voltage (IP) with Jumper CN3
Wire Gauges and Tightening Torques
Wire gauge and torque specifications are listed in Table 8.10. For simpler and more reliable wiring, use crimp ferrules on
the wire ends. Refer to the option manuals for the wire size and torque specifications of other options.

Terminal Block Terminal Function Description
TB1
<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.
A+ A+ pulse signal input
• Inputs for the A channel, B channel, and Z pulses from the PG encoder
• Signal level matches RS-422
A– A– pulse signal input
B+ B+ pulse signal input
B– B– pulse signal input
Z+ Z+ pulse signal input
Z– Z– pulse signal input
SD NC pin (open)
Open connection connectors for use when cable shields should not be
grounded
FE Ground Used as the shield ground termination point.
