■ 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.

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.
■ Programming Mode Details
The following actions are possible in the Programming Mode:
• Parameter Setting Mode: Access and edit all parameter settings
• Verify Menu: Check a list of parameters that have been changed from their original default values
• Setup Group: Access a list of commonly used parameters to simplify setup (see Simplified Setup Using the Setup
Group on page 95)
• Auto-Tuning Mode: Automatically calculates and sets motor parameters to optimize drive performance
