Parameter Level
The Parameter Level is the programming level where the parameters are
viewed and can be modified. Each Group contains several Parameters.
Parameters allow you to change certain specifications or values to meet the
needs of your particular application.
To change a Parameter value:
1. Use the arrow keys to select the parameter you would like to change.
2. Press [ * ] to enter the Setting mode. This places square brackets around
the value displayed in the lower left of the Display.
3. Press [Up Arrow] or [Down Arrow] to change the Parameter value.
4. Press [ * ] to save the selected value and exit Setting mode, or [Right
Arrow] or [Left Arrow] to cancel and return to previous value.
Note: Start-up Data and Operating Data are not Main or Group levels, but
define certain Parameters. Procedures for changing Start-up Data
Parameters A – K are not the same as those described above. Refer to
Chapter 3 – Start-up Data for Start-up Data details.
Figure 2-4 shows how to select a Parameter using the Control Panel Keypad.
