• I often see some confusion in various customers’ minds regarding encoder performance with automation systems which have servo drives or variable frequency drives (VFD). Some customers feel that when they are providing best in class encoders, the system must be highly accurate.

    Sounds logical? … Yes, but there are some other points to consider also.

  • By definition, Eccentricity is a measure of how much a roll deviates from being perfectly circular. Ideally, eccentricity should be zero, but in reality, it is never zero. Practically not a single roll is a perfect circle because it is produced using a machine which itself is prone to some machining errors (since it is product of some other machine and so on).
