2-124 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Motor Load Loss Speed [Mtr LoadLoss Spd]
Linear Number: 259
Default Value: 30.0 Hz
Minimum Value: 0.0 Hz
Maximum Value: 100.0 Hz
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the minimum speed at which the loss of load condition will be detected.
Generally there is lesser load at lower speeds, so this parameter helps avoid nuisance trips during
operation at lower speeds.
Motor Load Loss Delay [Mtr LoadLoss Dly]
Linear Number: 231
Default Value: 1.0 sec
Minimum Value: 0.0 sec
Maximum Value: 30.0 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time delay between the detection of the load loss condition and the actual
fault initiation.
Field Current Loss Delay [Field Loss Dly]
Linear Number: 559
Default Value: 30 sec
Minimum Value: 0 sec
Maximum Value: 60 sec
Access Level: Service
Read/Write: Read/Write
This parameter is used to specify the time interval during which the flux regulator is in limit, before the
drive trips on a field loss. Field Current is not directly measured in the control, so we look at the flux
regulator, which will go into limit on loss of field current.

Tachometer Loss Trip [Tach Loss Trip]
Linear Number: 235
Default Value: 2.0 Hz
Minimum Value: 0.0 Hz
Maximum Value: 10.0 Hz
Access Level: Service
Read/Write: Read/Write
This parameter specifies the level that the tachometer error must exceed before a tachometer loss fault is
indicated.
Tachometer Loss Delay [Tach Loss Delay]
Linear Number: 236
Default Value: 0.1 sec
Minimum Value: 0.0 sec
Maximum Value: 1.0 sec
Access Level: Service
Read/Write: Read/Write
This parameter specifies the time that the tachometer error must be greater than the trip level before a
tachometer loss fault is indicated.
