Connecting PG-X3 Option
Parameter Settings and Connections for Different Encoder Types
• Connecting a Single-Pulse Encoder
When using a single-pulse encoder in V/f with PG control mode, connect the pulse output from the PG to the option
and set drive parameter F1-21 to 0.
• Connecting a Two-Pulse Encoder
When using a two-pulse encoder, connect the A and B pulse outputs on the PG to the option and set F1-21 to 1.
When using a two-pulse encoder in Closed Loop Vector control mode, connect pulse outputs A and B from the encoder
to the corresponding terminals on the option.
• Connecting a Two-Pulse Encoder with Z Marker Pulse
When using a two-pulse encoder with Z marker pulse, connect the A, B, and Z pulse outputs to the corresponding
terminals on the option.
When using a two-pulse encoder in CLV/PM control mode, connect pulse outputs A and B from the encoder to the
corresponding terminals on the option.

Connection Diagram of PG-X3
Refer to Table 8.8 for a detailed description of the option board terminal functions.
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.
Refer to Setting the PG Encoder Power Supply Voltage on page 424
<1> Ground the shield on the PG side and the drive side. If noise problems arise in the PG signal, remove the shield ground from one end of the
signal line or remove the shield ground connection on both ends.
Note: The PG-X3 Option reads a maximum input frequency from the PG of 300 kHz. Be sure to select a PG with an output pulse
frequency of maximum 300 kHz when operating at maximum speed.
