Reference Switch
Many of the positioners are equipped with a direction sensing reference switch positioned
approx. in the middle of the travel range. It is recommended to approach the reference
switch always from the same direction to obtain best position repeatability.
Function: Optical, magnetic
Sensor resolution
The sensor can be the critical element of position resolution so it may be necessary to
specify the sensor resolution separately. Rotary encoder: Impulses per screw rotation. Linear
encoder: Smallest motion still detected by the sensor system.
Travel Range
The maximum possible travel range is limited by the length of the drive screw. A possible
gap between the limit switches determines the travel range.
