Different units can be defined for different axes (axis 1 to 4).
units depending on the type of the control target: mm, inch, degree, or PLS.
Different units can be defined for different axes (axis 1 to 4).
(Example) Different units (mm, inch, degree, and PLS) are applicable to different
systems:
mm or inch .... X-Y table, conveyor (Select mm or inch depending on the
machine specifications.)
degree ........... Rotating body (360 degrees/rotation)
PLS................ X-Y table, conveyor
PLS................ X-Y table, conveyor
When you change the unit, note that the values of other parameters and data
will not be changed automatically.
After changing the unit, check if the parameter and data values are within the
allowable range.
Set "degree" to exercise speed-position switching control (ABS mode).
