Operator Terminal Status Screens
The operator terminal has 9 status screens that may be accessed by pressing the STATUS key.
Each time the STATUS key is pressed the next status screen is displayed. The BACKSPACE key
can be used to scroll backwards through the status screens. The CLEAR Key will remove the
status display or clear the peak values. The following variables are available on status screens:
TABLE 5.2 Variables Available on Status Screens
All position values displayed on the operator terminal status screens are in user units, velocity
values are in user units per timebase, and current (torque) variables are in amps.
