Using DriveExplorer or DriveExecutive
When using DriveExplorer or DriveExecutive, the Converter parameters are
displayed under Port 0 and are organized into the normal menu of Files,
Groups, and Parameters. The control bar can be opened to show a stop and
start push button.
Verifying Feedback Parameters
Using the HIM, DriveExplorer or DriveExecutive, verify that reasonable
values are displayed for the following parameters in the Active Converter
Power Module:
•
Line to Line Voltage – Verify converter parameters 11 - [Input Voltage
RS], 12 - [Input Voltage ST], and 13 - [Input Voltage TR] display a
reasonable Line to Line RMS Voltage. Verify the voltage imbalance
displayed in parameter 16 - [V Imbalance] does not exceed 5.0%.
•
DC Link Voltage – Verify converter parameter 14 - [DcLink Voltage]
displays a reasonable DC Link Voltage.
•
AC Line Frequency – Verify converter parameter 40 - [Line Frequency]
displays a reasonable AC Line Frequency.
•
Ambient Temperatures – Verify converter parameter 30 - [Ambient
Temp] displays a reasonable ambient temperature. Verify parameter 32 -
[IGBT Junction Temp] displays the temperature of the liquid being
pumped through the coldplate.
