1.8.8 Setting User Units
When one of the motion axes is selected on the configuration tree, click on
its Configuration tab to set the user unit parameters. Changes to user
units will only take effect after a power cycle.
Rotary Motors:
The default User Unit for rotary motors is 1.0 = one motor
revolution. This User Unit configuration in the controller is independent of
the encoder resolution. Encoder resolution is read from the drive and is
factored at run time by the controller firmware.
Linear Motors:
The default User Unit for linear motors is 1.0 = one millimeter, however
Pn282 must be set correctly for the linear encoder scale used. Typically,
the linear scale pitch is 20 microns.
