When it comes to magnetic incremental linear encoders, sometimes the configurable performance parameters can be a tad obscure. One of the most puzzling is the feature called “Minimum Edge Separation”.
Just for review, a magnetic incremental linear encoder system consists of a precision-encoded magnetic tape and a precision magnetic reader head. It is a non-contact device and is an incremental measurement system. Incremental means the position is given as a series of pulses which must be counted by the controller. If the count is lost or corrupted for any reason (such as a power-down), the system must be re-zero’d to a known home position before controlled positioning/measuring can resume.
