FANUC Series 30i-MODEL A
Linear scale with distance-coded
reference marks
serial
Outline
By using High-resolution serial output circuit for the linear scale with
distance-coded reference marks (serial), the CNC measures the interval of
referenced mark by axis moving of short distance and determines the
absolute position.
This function enables high-speed high-precision detection by using
High-resolution serial output circuit.
It is available that using maximum stroke 30 meters length.
This is an optional function.
Details
The linear scale with distance-coded reference marks (serial) is combined
the irregular reference marked linear scale with the High-resolution serial
output circuit, it can detect the accurate position.
The CNC measures the interval of referenced mark by axis moving of short
distance and determines the absolute position, because of the interval of each
reference mark is different with regular interval.
It is not necessary that the axis is moved to the reference position for
establishment of reference position.
This function enables high-speed high-precision detection by using
High-resolution serial output circuit.
It is available that using maximum stroke 30 meters length.
- Connection
It is available under linear motor system and full closed system.
