"Power off and lose position, power on and return to zero? When selecting absolute or incremental encoders, consider these five key differences first."
After the incremental encoder is powered off, its position resets to zero, and it needs to return to zero every time it is powered on, posing downtime and safety hazards in long-stroke and multi-axis scenarios. The Fenac FNC series absolute value encoder maintains its position during power-off in single/multiple turns and supports SSI/BISS/Profibus/CANopen interfaces, eliminating the need for returning to zero. This article uses a comparative table to clarify the differences in returning to zero, power-off memory, anti-interference, accuracy, and cost.
Struggling with positioning accuracy issues? Selection and error control of internal parameters for inductive (eddy current) displacement sensors
Machine tools, hydraulic systems, and injection molding production lines often experience positioning drift due to wear from contact measurement or interference from oil contamination. This article delves into the working principle, key parameters, and selection logic of esitron inductive (eddy current) displacement sensors, aiming to assist engineers in mastering the key points of error control in non-contact measurement.
