Get
FLA Current
UINT
The present FLA setting. The potentiometer selects this value. The value is scaled by
the multiplier.
140
—
Get
AvgCurrent
UINT
Average of the three phase currents, scaled by the current multiplier
141
—
Get
Current Ll
UINT
Actual motor phase current L1, scaled by the current multiplier
142
—
Get
Current L2
UINT
Actual motor phase current L2, scaled by the current multiplier
143
—
Get
Current L3
UINT
Actual motor phase current L3, scaled by the current multiplier
144
—
Get
Ground current
UINT
RMS ground current, scaled by the current multiplier
150
—
Get
Maximum device FLA
UINT
This is the max FLA setting possible in this device. The value is scaled by the current
multiplier.
151
—
Get
Minimum device FLA
UINT
This is the min FLA setting possible in this device. The value is scaled by the current
multiplier.
152
—
Get
Current multiplier
UINT
This value indicates the multiplier applied to the current values. For example: If the
multiplier is 10 then all currents are read out in deci-amps. 1A => 10; Divide the given
current value (attribute 140, 141, 142, and so on) by the value in this location to
convert to amps.
153
—
Get
Current as a % of FLA
UINT
Presents the average current as a percent of the FLA setting.
154
—
Get
Ground Fault %
USINT
Percent of ground fault measured. GF% = GFC / ([0.5]*FLA)
