Pr.1 Unit setting
Set the unit used for defining positioning operations. Choose from the following
units depending on the type of the control target: mm, inch, degree, or pulse.
Different units can be defined for different axes (axis 1 to 4).
(Example) Different units (mm, inch, degree, and pulse) are applic able to different
systems:
mm or inch.....X-Y table, conveyor (Se lect mm or inch depending on the
machine specifications.)
degree........... Rotating body (360 degrees/rotation)
pulse.............. X-Y table, conveyor
When you change the unit, note that the values of other parameters and d ata
will not be changed automatically.
After changing the unit, check if the parameter and data values are with in the
allowable range.
Set "degree" to exercise speed-position switching control (ABS m ode).
