Description
Max. tolerance of the offset vectors (only for tolerance "Yes")
Max. tolerance of the rotary axis vectors (only for tolerance "Yes")
Limit value of the minimum inside angle of the measured triangle of the three meas‐
urements of the rotary axis (see "Mounting the calibration" above).
● Yes for kinematics mounted permanently on the machine
● No for changeable kinematics (e.g. interchangeable heads)
