D Shielded twisted-pair wires must be used for signal lines.
D 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.
D The length of the pulse generator’s wiring must not be more than 100 meters.
D The direction of rotation of the PC can be set in user constant F1-05. The
factory preset if for forward rotation, A-phase advancement.
