Note 1. Twisted-pair shielded wire must be used for signal lines.
Note 2. 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.
Note 3. The length of the pulse generator’s wiring must not be more than 50 meters.
