Wiring the PG-B2 card
The following illustrations show wiring examples for the PG-B2 using the option cards power supply or an
external power source for supplying the PG.

Precautions:
• The length of the pulse generator's wiring must not be more than 100 meters.
• The direction of rotation of the PG can be set in user parameter F1-05. The factory setting is A-phase
leading in forward direction (motor shaft turning counterclockwise seen from motor shaft side).
• The pulse monitor output factor can be changed using parameter F1-05.
• Refer to page 2-31, Wiring Precautions for general precautions.
