Protection
•Shielded twisted-pair wires must be used for signal lines.
•Do not use the PG-B2'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 100 meters.
•The direction of rotation of the PG can be set in parameter F1-05 (PG Rotation).
The factory preset is for forward rotation, A-phase advancement.
