Save .ddf Values Button
Once the user has entered the data for the motor they are
using, they may or may not wish to save the motor data to
the SPMotor.ddf file so it can be easily recalled at a later
time. If the user does not save the motor data to the
SPMotor.ddf file, then the motor data will only reside in the
specific application configuration file that it has been
entered into.
In order to save the motor data to the SPMotor.ddf file, the
user simply clicks on Save .ddf Values on the Motor Tab.
Doing so will take all the parameter values and write them
to the SPMotor.ddf file automatically.
When saving to the .ddf file, if PowerTools Pro finds that a
motor already exists with the same name, the User Defined
Motor Name Conflict dialog box shown in Figure 56 will
appear. The user must then decide how to proceed with
saving the motor data .ddf file.
Figure 56: User Defined Motor Name Conflict
The User Defined Motor Name Conflict dialog box presents
the user with four options on how to proceed with saving
the motor data. Those four options are.
1. Create New Motor entry In .DDF File
The user can select to keep the existing data and create a
new entry into the SPMotor.ddf file with a different name.
After selecting this option, the user simply enters a new
name in the Please Enter Name text box, shown in Figure
56. Then click OK, the data will be written to the .ddf file
using the new motor name.
2. Overwrite existing .DDF file motor entry
The user can select to overwrite the existing data in the .ddf
file with the current data in the Motor Parameters column.
If this option is selected, the data in the .ddf file will be
overwritten and lost forever. The overwritten data cannot
be recovered.
If the user attempts to overwrite data for a Standard Motor
(in the SPStdMotor.ddf file), the operation will be canceled
and the user will be notified that they cannot proceed.
Figure 57 shows the error message that will be produced
when the user attempts to overwrite a standard motor. In
this case, the user would need to change the motor name
before saving to the .ddf file.
