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.
