n Drive Mode Details
The following actions are possible in the Drive Mode:
• Run and stop the drive
• Monitor the operation status of the drive (frequency reference, output frequency, output current, output voltage, etc.)
• View information on an alarm
• View a history of alarms that have occurred
Figure 4.6
illustrates how to change the frequency reference from F 0.00 (0 Hz) to F 6.00 (6 Hz) while in the Drive Mode.
This example assumes the drive is set to LOCAL.

Figure 4.6 Setting the Frequency Reference while in the Drive Mode
Note: The drive will not accept a change to the frequency reference until the ENTER key is pressed after the frequency reference is entered. This feature prevents accidental setting of the frequency reference. To have the drive accept changes to the frequency reference as soon as changes are made without requiring the ENTER key, set o2-05 to 1.
n Programming Mode Details
The following actions are possible in the Programming Mode:
• Parameter Setting Mode: Access and edit all parameter settings.
• Verify Menu: View a list of parameters that have been changed from the default values.
• Setup Group:
Access a list of commonly used parameters to simplify setup ( Refer to Simplified Setup Using the Setup
Group on page 164
).
• Auto-Tuning Mode: Automatically calculate and set motor parameters to optimize drive performance.
