Configure the Drive
In order to tailor the drive to your motor and application, a number of elements must be defined in
the drive. The section describes how you will set or 'configure' these elements of the drive, via
this terminal. You will learn how to:

Change a parameter setting.

Assign a variable or parameter to an Analog Port.

Selectively enable or disable (ie. Mask) certain faults.

Define your own faults attached to external inputs.

Define the information sent to your optional PLC connection.

Save and Restore your settings in the drive.

Select an alternate language (if previously loaded in terminal).
Enter/Modify a Password (Access)
The drive is protected from changes via a password consisting of a number between 0 and
65535. You can view any screen of data for the drive without knowing the password. However to
change any piece of data, you must first gain access to it via the password value.
The terminal is always in one of two modes, either Restricted or Unrestricted. Restricted mode
means that you are restricted to only viewing the drive operation, you can not make any changes
to the drive setup. Unrestricted mode means you have full unrestricted access to any data in the
drive the terminal is capable of accessing.
This password value is the key to changing the mode of the drive from restricted to unrestricted.
The screen shown in Figure 28 is accessible from within a number of screens where the
unrestricted mode is required for operations such as:
1) [F10] key on the Top Level Menu,
2) [F8] key on the Modify Parameter screen,
3) [F8] key on the Setup Screen,
4) [F8] key on the Transfer Screen,
5) [F8] key on the Diagnostic Setup screen.
