5.10 Parameter security
There are two independent levels of security that can be enabled /
disabled in the Unidrive. This gives four possible combinations of
security settings as shown in the table below:
RW = Read / write access
RO = Read only access
The default settings of the drive are standard security closed and user
security open, i.e. read / write access to Menu 0 with the advanced
menus (i.e. menus 1 to 20) not visible.
5.10.1 Standard security
Standard security prevents read and write access to the advanced menu
parameters.
Opening standard security
Set parameter xx.00 to 149 and press the button.
Closing security
Set parameter xx.00 to 2000 and press the button or cycle the
power to the drive.
This action also closes user security if it has been enabled.
Disabling standard security
Set parameter 0.34 to 0 and press the button.
This action also disables user security if it has been enabled.
Enabling standard security
Set parameter 0.34 to 149 and press the button.
5.10.2 User security
User security prevents write access to all parameters except xx.00.
Setting user security
Enter a value between 1 and 256 (except 149) in parameter 0.34. Once
the button has been pressed the value reverts to 149 to hide the
security code which has been set.
Save parameters by setting parameter xx.00 to 1000 and press the
button.
Opening user security
Enter the security code into parameter xx.00.
Closing user security
Set parameter xx.00 to 2000 and press the mode button or cycle the
power to the drive.
This action also closes standard security if it has been enabled.
Disabling user security
Set parameter 0.34 to 0 and press the button to disable both user
and standard security
Set parameter 0.34 to 149 and press the button to disable user,
but set standard, security.
