Note: The drive will not accept a frequency reference set value unless the ENTER key is pressed after the frequency reference is
entered. This feature prevents accidental setting of the frequency reference. By setting o2-05 (Frequency Reference Setting
Method Selection) to 1 (Enabled), the drive will accept the frequency reference while it is being adjusted on the digital operator.
■ Programming Mode Details
The following actions are possible in the programming mode:
• Verify Function: Verify parameter setting changes from original default values.
• Setup Group: Access a list of commonly used parameters to simplify setup.
• Parameter Setting Mode: Access and edit all parameter settings.
• Auto-Tuning: Automatically calculates and sets motor parameters for Open Loop or PM Vector control to optimize
the drive for the motor characteristics.
The Setup Group within the Programming Mode
In Setup Group, the user can access the minimum group of parameters required to operate the application.
Note: Setup Group parameters are listed in Table 4.4.
Figure 4.5 illustrates the keys to press to enter the Setup Group.
In this example, the source of the frequency reference is changed from the control circuit terminals to the LED Operator
(i.e., b1-01 is changed from 1 to 0).
