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 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)
pulse .............. 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).
