Fig 2.19 Wiring a 12 V Voltage Input
•
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 (328 ft).
