Rockwell Automation PowerFlex 7000 Technical Data

2-120 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Motor Protection Parameters
Motor Over current Trip [Mtr OvrCur Trp]
Linear Number: 177
Default Value: 1.75 pu
Minimum Value: 0.00 pu
Maximum Value: 4.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level the motor current must exceed before a motor over current fault is
indicated.
Motor Over current Delay [Mtr OvrCur Dly]
Linear Number: 178
Default Value: 100 msec
Minimum Value: 0 msec
Maximum Value: 500 msec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the motor current must remain above the trip level before a motor over
current fault is indicated.
Motor Over voltage Trip [Mtr OvrVolt Trp]
Linear Number: 181
Default Value: 1.20 pu
Minimum Value: 0.00 pu
Maximum Value: 2.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level the motor voltage must exceed before a motor over voltage fault is
indicated.
Motor Over voltage Delay [Mtr OvrVolt Dly]
Linear Number: 182
Default Value: 0.5 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 voltage must remain above the trip level before a motor over
voltage fault is indicated.
Motor Neutral Over voltage Trip [Mtr NeutVolt Trp]
Linear Number: 189
Default Value: 0.20 pu
Minimum Value: 0.00 pu
Maximum Value: 1.50 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level the motor neutral to ground voltage must exceed before a motor
neutral over voltage fault is indicated. For line reactor drives, you may find the default setting is too low
and may have to be increased to 0.80 pu for normal operation.
