Encoder Cable Length Limitations, Precautions & Solutions
2nd February 2024
The speed and position signals of rotary encoders often need to be transmitted over long distances that are questionable for reliability. The distance from the point of “pick up” to the controller (PLC, VSD, or display) needs to be considered and cannot be an indefinite length. Certain measures can be taken to avoid signal problems. Problems caused by cable runs that are too long can present intermittently or may only present after some time, as interference conditions change, or electronic components such as capacitors age. Steps should be taken at the design stage of a system to avoid such
