3.3 COMPARISON OF PROGRAM MODE AND DRIVE MODE
Displays that appear on the Digital Operator differ according to the selected mode of
operation. The PRGM (Program) mode is used to change constant settings in the Drive's
memory to configure it to the requirements of the application. The DRIVE mode is used
primarily to control (i.e. start and stop) Drive output for motor/machine operation. The
only constants that can be changed while in the DRIVE mode (An- or bn- settings, or Un-
display selection) are those that will not have a critical effect on operating characteristics.
The constant group to be displayed, in either mode, is selected by pressing the DSPL key.
