10.4.1 Locking access to parameters

Ensure that the "Long Parameter mode (Par L) has been selected as shown in Real Time Operation.
1. Go to Parameter 1603 (Long Parameter group) and enter in your chosen parameter access code.
2. Press the Navigate button to exit and parameter 1603 will then be hidden and all parameters will be "Read only" (except
for Parameter 1602 which will remain "Read Write").
3. Access to parameters via the REMOTE PANEL will now be prevented.
NOTE: Operational information (e.g. speed, current, power etc) can still be accessed as normal and the drive can still be
controlled from the keypad.

10.4.2 Un-Locking access to parameters

1. Enter into parameter 1602 the same value as 1603 (as chosen above).
2. All parameters will now be "Read Write" and parameter 1603 will become visible and show the value which was originally
programmed as the parameter access code.
3. To disable this feature set parameter 1603 to zero and then parameter 1602 to zero.
NOTE: In the event of losing the drive password, please contact ABB for support to be provided with an unlock code. The
drive serial number (located on the drive nameplate) is required to be provided.
10.5 Resetting Parameters to Factory Default
The following procedure will reset all drive parameters to their factory default values as defined in the Parameter Definition
tables in Chapter 10. This function should only be performed to set the drive back to a known state and is not
required for normal use.
Hold down "UP", "DOWN" and "STOP" for 2 seconds. Drive will now display "p-def". Now, press the "STOP" key, and
stop will be displayed. Drive is now reset to Factory Defaults.
NOTE: Factory Reset of Parameters will remove all pre-programmed factory settings for motor data. Refer to 7.2 Quick
Start Parameter Data for a listing of parameters that should be set for proper control and operation of the EC
Titanium Motor in the event a factory reset is performed.
