6.4 Saving parameters
Parameters are automatically saved when the MODE key is pressed when going
from parameter edit mode to parameter view mode.
6.5 Parameter access
There are 3 levels of parameter access controlled by Pr 10. This determines which
parameters are accessible. See Table 6-1.
The setting of the user security Pr 25 determines whether the parameter access is read
only (RO) or read write (RW).
Table 6-1
6.6 Security codes
Setting a security code allows view only access to all parameters.
A security code is locked into the drive when Pr 25 is set to any other value than 0 and
then LoC is selected in Pr 10. On pressing the MODE key, Pr 10 is automatically
changed from LoC to L1 and Pr 25 will be automatically set to 0 so as not to reveal the
security code.
Pr 10 may be changed to L2 or L3 to allow view only access to parameters.
6.6.1 Setting a security code
•Set Pr 10 to L2.
•Set Pr 25 to the desired security code e.g. 5
•Set Pr 10 to LoC.
• Press the MODE key
•Pr 10 will now be reset to L1 and Pr 25 will be reset to 0.

• Security will also be set if the drive is powered down after a security code has been
set into Pr 25.
