Self-Diagnostic Encoders Find Problems Before They Stop Your Machinery
Encoders are the mystery machine of the industrial landscape: A mechanical device at heart, but with electronic outputs. Encoders are often installed by motor companies or outside integrators, then connected to both PLCs and drives. They frequently fall in the “all other” scope of job responsibility and troubleshooting. Most encoders are a “black box” with no diagnostic features at all, not even a power light! Troubleshooting an encoder requires an oscilloscope and some engineering knowledge, or a dedicated encoder diagnostic device. Both are typically in short supply at 3AM when a problem arises and production comes to an abrupt halt.
