7000-TD002A-EN-P – September 2007
Motor Current Unbalance Value [Motor Cur Unbal]
Linear Number:
263
Minimum Value:
0.00
Maximum Value: 1.00
Access Level:
Service
Read/Write:
Read
Only
This parameter specifies the value of current unbalance between the 3 phases on the drive output
measured at the LEMs. A fault is issued when the value exceeds the parameter
Mtr CurUnbal Trp
(208)
for the duration set in
Mtr CurUnbal Trp
(214).
Motor Flux Unbalance Value [Motor Flux Unbal]
Linear Number:
619
Minimum Value:
0.00
Maximum Value: 1.00
Access Level:
Service
Read/Write:
Read
Only
This parameter specifies the value of flux unbalance between the 3 phases on the drive output, measured
with the voltage sensing board. A fault is issued when the value exceeds the parameter
Mtr FluxUnbal
Trp
(585) for the duration set in
Mtr FluxUnbal Trp
(586).
Fault Output [Fault Output]
Linear Number:
490
Minimum Value:
0
Maximum Value: 1
Access Level:
Service
Read/Write:
Read
Only
This parameter is used for troubleshooting and allows the user to properly use a chart recorder,
oscilloscope or a similar device to trigger on a drive fault and capture useful test point data. The
parameter goes from 0 to the maximum value of 1 whenever any fault occurs. Assigning this parameter
to any one of the test points on the DPM or 0-10V outputs on the Analog Control Board, an output that will
change state from 0V to 10V on a fault will be produced. This output can be used as a trigger for
capturing other drive data from test points during a fault.
Warning Output [Warning Output]
Linear Number:
700
Minimum Value:
0
Maximum Value: 1
Access Level:
Service
Read/Write:
Read
Only
This parameter is used for troubleshooting and allows the user to properly use a chart recorder,
oscilloscope or a similar device to trigger on a drive fault and capture useful test point data. The
parameter goes from 0 to the maximum value of 1 whenever any warning occurs. Assigning this
parameter to any one of the test points on the DPM or 0-10V outputs on the Analog Control Board, an
output that will change state from 0V to 10V on a warning will be produced. This output can be used as a
trigger for capturing other drive data from test points during a warning condition.
Scope Trigger [Scope Trigger]
Linear Number:
689
Minimum Value:
0
Maximum Value: 1
Access Level:
Service
Read/Write:
Read
Only
This parameter is set high when the Trending is triggered. The parameter can be assigned to a Test
Point in order to trigger a scope.
