Rockwell Automation PowerFlex 7000 Technical Data

Parameter Descriptions 2-123
7000-TD002A-EN-P – September 2007
Motor Flux Unbalance Trip [Mtr FluxUnbalTrp]
Linear Number: 585
Default Value: 0.05 pu
Minimum Value: 0.00 pu
Maximum Value: 1.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level of the unbalance in the motor flux that will cause a motor unbalance
fault.
Motor Flux Unbalance Delay [Mtr FluxUnbalDly]
Linear Number: 586
Default Value: 1.0 sec
Minimum Value: 0.0 sec
Maximum Value: 10.0 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the motor flux unbalance value must remain above trip level before a
flux unbalance fault is indicated.
Motor Current Unbalance Trip [Mtr CurUnbal Trp]
Linear Number: 208
Default Value: 0.05 pu
Minimum Value: 0.00 pu
Maximum Value: 1.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level of motor current unbalance that will cause the drive to trip.
Motor Current Unbalance Delay [Mtr CurUnbal Dly]
Linear Number: 214
Default Value: 1.0 sec
Minimum Value: 0.0 sec
Maximum Value: 5.0 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the motor current unbalance value must remain above trip level before
a current unbalance fault is indicated.
Motor Load Loss Level [Mtr LoadLoss Lvl]
Linear Number: 246
Default Value: 0.25 pu
Minimum Value: 0.00 pu
Maximum Value: 1.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the minimum percent of rated load at which the drive will assume that there is a
loss of load. If the load drops lower than this parameter, and the speed is greater than Mtr LoadLoss Spd
(259), the drive will initiate the fault after the Mtr LoadLoss Dly (231) expires. The control uses the
parameter Torque Reference (P291) as the load reference.
