n Wiring the 3G3FV-PPGB2
Wiring examples are provided in the following illustrations for the 3G3FV-PPGB2.
• Shielded twisted-pair wires must be used for signal lines.
• Do not use the pulse generator's power supply for anything other than the pulse generator (encoder).
Using it for another purpose can cause malfunctions due to noise.
• The length of the pulse generator's wiring must not be more than 30 meters.
• The direction of rotation of the PG can be set in parameter F1-05. The factory preset if for forward rota-
tion, A-phase advancement.

•
When connecting to a voltage-output-type PG (encoder), select a PG that has an output impedance with
a current of at least 12 mA to the input circuit photocoupler (diode).
• The pulse monitor dividing ratio can be changed using parameter F1-06.
