2-110 Parameter Descriptions

Line Over Current Trip [Line OvrCur Trp]

Linear Number: 161
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 line current must exceed before a line over current fault is
indicated. For 18-pulse drives, a line over current trip will prevent the input contactor from closing for five
minutes. Depending on the severity of line over current trip, the contactor may be locked out indefinitely.
This is being done to prevent damages to the input transformer.

Line Over Current Delay [Line OvrCur Dly]

Linear Number: 162
Default Value: 10 msec
Minimum Value: 0 msec
Maximum Value: 100 msec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the line current must remain above the trip level before a line over
current fault is indicated.

Line Over voltage Trip [Line OvrVolt Trp]

Linear Number: 165
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 line voltage must exceed before a line over voltage fault is
indicated.

Line Over voltage Delay [Line OvrVolt Dly]

Linear Number: 166
Default Value: 10 msec
Minimum Value: 0 msec
Maximum Value: 1000 msec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the line voltage must remain above the trip level before a line over
voltage fault is indicated.
Rectifier Over Voltage Trip [Rec OvrVolt Trp]
Linear Number: 173
Default Value: 1.50 pu
Minimum Value: 0.00 pu
Maximum Value: 2.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level the Rectifier input voltage must exceed before a Rectifier over voltage
fault is indicated. The protection scheme has been realized in hardware on ACB.
