The "Auto Update" features allows an external tool to set the
Axis Sequence and read performance values in an XML report. The
external tool can be a profile generator and/or an optimizing tool
that adjusts the Sequence with each iteration. The XML report
contains all key performance values including Motor Peak
Torque/Force, Motor Cont Torque/Force, Inverter Peak Current,
Inverter Cont Current, Infeed Peak Power, Infeed Cont Power,
Bleeder Power Power, Bleeder Cont Power, etc.
Step 1: To start the process, point to a
Sequence text file by using the Import
Sequence feature. Then the "Auto Update" and
"Import Sequence" buttons appear.
Step 2: Next click the "Auto Update" button in
the Sequence. When in Auto Update mode, the "Auto Update" button
will flash as the Sequence form looks for an updated Sequence text
file.
Step 3: Change the source sequence file. Once
an updated Sequence file is detected, it is immediately loaded and
processed, and then the key performance results are saved in an XML
report file.
Step 4: The external tool can read the XML
report file, then adjust and generate a new Sequence text file, and
so on, to optimize the Sequence according to the external tool's
target parameters.
Step 5: When done, de-select the
"Auto Update" button to return the Sequence back to normal
mode with the last Sequence provided by the external tool.
The XML report file returned by the program includes extensive
detailed performance information for all components in each slot in
the power group. The XML report files are in the same folder as the
Seq.txt file in the "Reports" subfolder.
One of the first elements in the report is the Power Group
element:
<PowerGroup>
<PowerGroupNumber>1</PowerGroupNumber>
<PowerGroupDescription>Power
Group</PowerGroupDescription>
<U_OverallStatus>CRITICAL</U_OverallStatus>
<U_Overall>91.5655521151247</U_Overall>
</PowerGroup>
In general, this is the first place the optimization tool will
look before probing the XML file for more details. If there is a
Critical alarm and/or the overall utilization is too high, then the
optimization tool may pass on the current sequence and try another.
If there is a Warning or Critical status, the status element will
be <U_OverallStatus>CRITICAL</U_OverallStatus>.
This is the Motor element included in the XML report file:
<Motor>
<Vendor>ABC</Vendor>
<Model>DG56A65</Model>
<Type>PMSM</Type>
<CoolingType>Natural
convection</CoolingType>
<U_OverallStatus>CRITICAL</U_OverallStatus>
<U_Overall>91.5655521151247</U_Overall>
<U_PeakTorque>79.3798735670792</U_PeakTorque>
<U_ContTorque>72.1486428639502</U_ContTorque>
<U_I2t>91.5655521151247</U_I2t>
<InertiaMismatch>1.85379784313725</InertiaMismatch>
</Motor>
The key performance elements are the Utilization (U) elements.
In this case, the motor's I2t has the highest utilization with
91.5656%, and therefore is the value used for overall utilization,
<U_Overall>. In this case, the motor's status is Critical as
shown by <U_OverallStatus>CRITICAL</U_OverallStatus>.
This implies that the motor's I2t margin limit is likely 10%. Ie.
I2t >90% is considered a critical alarm in this example.
So let's take the same example as above, but in the project, set
the motor's I2t margin limit = 5%. In this case, the Power Group
and Motor elements are shown, now with
<U_OverallStatus>OK</U_OverallStatus>, indicating the
power group and motor are OK with no margin limits exceeded.
<PowerGroup>
<PowerGroupNumber>1</PowerGroupNumber>
<PowerGroupDescription>Power
Group</PowerGroupDescription>
<U_OverallStatus>OK</U_OverallStatus>
<U_Overall>91.5655521151247</U_Overall>
</PowerGroup>
<Motor>
<Vendor>ABC</Vendor>
<Model>DG56A65</Model>
<Type>PMSM</Type>
<CoolingType>Natural
convection</CoolingType>
<U_OverallStatus>OK</U_OverallStatus>
<U_Overall>91.5655521151247</U_Overall>
<U_PeakTorque>79.3798735670792</U_PeakTorque>
<U_ContTorque>72.1486428639502</U_ContTorque>
<U_I2t>91.5655521151247</U_I2t>
<InertiaMismatch>1.85379784313725</InertiaMismatch>
</Motor>
Similar performance details are provided for Inverters, Infeed,
Bleeder and ESM modules, as well as Gearboxes and Transformations,
Linear Actuators, Pumps, and other mechanisms, for all slots in the
power group.
