7.6 Performing a reset to factory settings
Overview
All converter parameters can be restored to a defined original state by performing a reset to
factory settings.
The original state can be restored by resetting the parameters to factory default by means of
P0970. These factory-set values are indicated in the parameter list by means of the
abbreviation "Def".
After a reset to factory settings, the following default settings will apply to the converter:
● Command and setpoint sources reset to fieldbus communication
● Control mode: basic V/f characteristic (P1300 = 0)
● Induction motor (P0300 = 1)
To facilitate the process of performing a reset to factory settings, the STARTER software
offers self-explanatory buttons and operator dialogs for both the standard and fail-safe
parameters.
Note
When the parameters are reset to the factory settings, the data transfer memory is
reinitialized. As a result, data transfer will be suspended while the reset process is being
performed.
WARNING
Fail-safe parameters
If standard frequency converters are used only the reset to factory defaults by means of
P0970 = 1 is of relevance.
If using frequency converters with fail-safe functions you have two reset options:
• P0970 = 1 only resets parameters which are irrelevant to fail-safe functions (application
parameters).
If P0970 = 1 is used to reset factory defaults on a frequency converter with fail-safe
functions all application parameters will be reset, however, any parameter settings
relating to fail-safe functions will be retained. That is, it is not necessary to carry out an
acceptance test.
• P0970 = 10 (password protected) only resets parameters which relate to fail-safe
functions.
An acceptance test must be carried out if parameters relating to fail-safe functions have
to be changed.
