Checking the protective circuit
The CMM is equipped with a protective circuit which monitors drive-
forces during bridge positioning movements in the x and y axes. The
shearing force monitoring is effective in all operating modes.
Function of the protective circuit
Drives must cut out
automatically.
If the traveling motion is obstructed by a collision in the x or y axis and
the shearing force therefore exceeds a value of approx. 150N, the
drives must cut off automatically.
Danger!
In order to ensure the safety of the CMM during measurement, the
function of the protective circuit must be checked regularly.
• Check the protective circuit on a monthly basis.
Check
