Inverter Diagnostics Result #2
[Inverter Diag 2]
The results of the Transistor Diagnostic
Tests are given in parameters 258 & 259.
If any of the bits shown below are set, then
a problem with the associated test is
indicated.
0 = Transistor U upper shorted
1 = Transistor U lower shorted
2 = Transistor V upper shorted
3 = Transistor V lower shorted
4 = Transistor W upper shorted
5 = Transistor W lower shorted
Iq OFFSET
[Iq Offset]
This parameter contains the LEM U offset
required to null the current error. (no motor
current flowing) This offset is set automati-
cally by running the transistor diagnostics.
Id OFFSET
[Id Offset]
This parameter contains the LEM W offset
required to null the current error. (no motor
current flowing) This offset is set automati-
cally by running the transistor diagnostics.
Phase Rotation Current Reference
[Ph Rot Curr Ref]
This parameter sets the current reference
that will be used when the Phase Rotation
test is run (Parm 256, bit 1)
Phase Rotation Frequency Reference
[Phase Rot Freq Ref]
This parameter sets the frequency refer-
ence that will be used when the Phase
Rotation test is run (Parm 256, bit 1)
Motor Current Magnitude Feedback
[Motor Cur Fdbk]
Displays the actual RMS value of the motor
current as determined from the LEM cur-
rent sensors. This data is averaged and
updated on a 50 millisecond basis.
Motor Voltage Magnitude
[Motor Volt Fdbk]
Displays the actual Line–to–Line RMS val-
ue of motor voltage. This data is averaged
and updated on a 50 millisecond
basis.
