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:

mmor 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).
