7.3 Example of Setting Motion Parameters for the Machine
7-47
7
(a) Parameter Setting Example Using Ball Screw
In the above machine system, if the requirement is reference unit = output unit = 0.001 mm, the setting of
each parameter will be as follows:
(b) Parameter Setting Example Using Rotating Load
In the above machine system, if the requirement is reference unit = output unit = 0.1
°
, the setting of each
parameter will be as follows:
