îš„Wiring the PG-D2
Wiring examples are provided in the following illustrations for the PG-D2.
• 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 100 meters.
