6.2 Safety Notes for Parameter Changes
Only Siemens trained personnel are authorized to change drive parameters.
Familiarize yourself with the following safety notes and preferentially contact Siemens customer
service before changing the default conguration.
CAUTION
Changing parameter values
Changes to parameter values may result in drive trip, instability or damage of the drive parts.
Rated input and output variables determine internal scaling for protection, stability and
control, and must never be changed from actual drive and motor ratings.
Do not change settings of any of the following parameters unless you are completely certain
that the change is safe.
If the changes have to be done, make sure that while you change parameter settings the drive
is not running and run is inhibited.
NOTICE
Entering correct parameter values
Entering parameter values may impact drive functions severely.
Do not enter parameter values unless you are completely sure of the eect your changes will
have.
You are responsible for providing correct parameter values.
Note
Consulting Siemens applications engineering
The parameters discussed in this chapter are based on hardware used within the drive and on the
design limits of drive components.
Do not change these settings in the eld to match the conditions on the site unless hardware
modications have been made and Siemens applications engineering approves of these
changes.
Note
Preventing unauthorized parameter changes
To prevent unauthorized changes to the parameters, you can set SOP
ag KeySwitchLockOut_O to true via a key-lock switch. You will be able to display all
parameters as usual. See Chapter Operating the Software for information about SOP ags.
Additionally, you can modify the password for security levels via the security edit function at
security level 7. See Section Security Access Levels and Codes for further information.
