Linear guide
1
The MF50 use a linear guide assembled with a ball retainer that efficiently eliminates
friction between adjacent balls. This achieves low noise, long service life and long
maintenance-free operation.
Magnetic scale and magnetic head
The magnetic scale utilizes YAMAHA's superb magnetic signal detection technology
developed in-house. The scale is made of a special alloy that retains a high-strength
magnetic field with virtually no weakening over time. Integrating it with a magnetic head
yields an astonishingly high resolution of one micrometer. Fully closed control directly
detects the table (slider) position for stable and highly precise positioning.
c
CAUTION
Do not bring a strong magnet close to the magnetic scale. A strong magnet
may erase the information recorded on the scale and cause the robot to
malfunction. A magnetic force of about 10mT (100 Gauss) does not cause
any problem.
As shown in the photos below, for example, bringing the magnetized side of
a magnetic base close to the side of the robot may erase the information on
the magnetic scale, so use caution.
c
CAUTION
The magnetic flux slightly leaks from the robot surface. (Max. 10mT)
When a device (sensor) that responds to the magnetism is installed, it may
respond incorrectly. Install such device 100 mm or more apart from the
robot, make the fine adjustment to eliminate incorrect response, or use a
device designed for the strong magnetic field.
