Hello, These motors that we use in a system we developed actually use absolute encoders. What is the probability that the abosulte encoders of these motors will break down or the encoder value read will deviate? I want to take precautions accordingly, but if this is already a very difficult or impossible scenario, I may not do anything about it. For example, let’s say I read an encoder value like 1230321 and after processing it, I get a position value for myself. How difficult is the scenario for this encoder value to suddenly change or get corrupted?
Hi there,
using any of the integrated encoders means you do not have to worry about any of the reading or checking yourself. In fact I have never heard of anyone trying to process the values for themselves. Using an EnDat 2.2 encoder (fully digital), the encoder and the drive have various checks to do integrity checking (e.g. a CRC checksum).
Sudden changes only occur when the encoder gets loose - and that means you have more issues at hand than the encoder itself.
The thing to worry about on your side should be to not exceed the loads on the axis, especially but not only the axial load.
Best regards
