Enums:
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.

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.
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]
Parameter Number 262
Parameter Type Sink
Display Units x.x%
Drive Units 4096 = 100.0% Motor Current
Factory Default 50.0%
Minimum Value 0.0%
Maximum Value 100.0%
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]
Parameter Number 263
Parameter Type Sink
Display Units x.x Hz
Drive Units 128 @ 1 Hz
Factory Default 3.0 Hz
Minimum Value – 30.0 Hz
Maximum Value +30.0 Hz
This parameter sets the frequency refer-
ence that will be used when the Phase
Rotation test is run (Parm 256, bit 1)
