Using DriveExecutive
When using DriveExecutive, the Active Converter parameters are displayed
in a linear list. Uploading reads parameter values from all DPI peripherals
but downloading parameters only write to the Inverter. To download
parameter values to the Active Converter, you must first select the
Converter.
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.
