180 Actual signals and parameters

Fieldbus equivalent

Example: If 2017 MAX TORQUE 1 (see page 225) is set from an external control
system, an integer value of 1000 corresponds to 100.0%. All the read and sent values
are limited to 16 bits (-32768...32767).
Storing the parameters
All parameter settings are stored automatically to the permanent memory of the drive.
However, if an external +24 V DC power supply is used for the drive control unit, it is
highly recommended to force a save using parameter 1607 PARAM SAVE before
powering down the control unit after any parameter changes.
Default values with different macros
When the application macro is changed (parameter 9902 APPLIC MACRO), the
software updates the parameter values to their default values. The table below shows
the parameter default values for different macros. For other parameters, the default
values are the same for all macros (shown in the parameter list starting on page 191).
If you have made changes to the parameter values and want to restore the default
values, you must first select another macro (parameter 9902 APPLIC MACRO), save
the change, select the original macro again and save. This restores the default
parameter values of the original macro.
