Wiring the PG-D2
Wiring examples are provided in the following illustrations for the PG-D2.
Three-phase
200-240 Vac
(380-480 Vac)
•
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.
