Setting Up Parameters
Encoder Type
The supported values for this parameter are 1 and 0. If set to a 1 the drive uses the Encoder Marker angle as well as
the Encoder U Angle for commutation. If this parameter is set to a 0, the drive uses only the Encoder U Angle.
Values from Drive Column
The Values from Drive column is a group of parameters that are constantly being read from the drive. The theory of
operation is that the user will often perform an Auto-Tune function that reads/measures/calculates data. The results of
those measurements are read from the drive and displayed in the Values from Drive column. Once they are displayed
in PowerTools Pro (in the Values From Drive column) the user can apply those values to the Motor Parameters column
by clicking on the Apply to Config. button, in the middle of the Motor view (this button looks like a series of arrows pointing
from the Values from Drive column towards the Motor Parameters column).
The values in the Values from Drive column are not saved as part of the configuration file. To save these values, the
user must use the “Apply to Config” button to save them.
This column is only functional when online with the device. When offline, the values in the Values from Drive column will
all read zero.
Apply to Config. Button
When the user runs the Auto-Tune feature PowerTools Pro reads the results of the Auto-Tune and displays them in the
Values from Drive column of the Motor view. After the Auto-Tune, the measured values are only saved in the Drive NVM,
and not in the FM3/4 module. Therefore, in order to store the values in the FM module, the Auto-Tune values must be
applied to the configuration file. When the user presses “Apply to Config.”, the values in the “Values From Drive” column
are transferred into the Motor Parameters column. Then the values must be downloaded by downloading the entire
configuration file using Device > Download.
Run Auto-Tune Button
The drive has the ability to run an Auto-Tune operation thereby measuring several different motor parameters. Doing so
allows the drive to obtain certain parameters that are not typically provided by the motor manufacturer, and also
optimizes other drive parameters to work properly with the connected motor/load.
PowerTools Pro allows the user to initiate the Auto-Tune feature from the Motor view.
The following table shows which parameters must be entered in order to run the Auto-Tune feature, and which
parameters are measured by the Auto-Tune.
Some Auto-Tunes cause motion while others do not. It is important to read and understand the warnings and instructions
on the Auto-Tune windows. It is strongly recommended to unload the motor if Auto-Tune Mode #3 is commanded.
When online with the drive, to initiate an Auto-Tune, click RunAuto-Tune button. The Auto-Tune dialog box opens and
contains warnings and instructions related to the Auto-Tune procedure, as well as selection of the Auto-Tune mode. An
example of one of the Auto-Tune windows is shown in Figure 39.
