Parameter Descriptions 2-113
7000-TD002A-EN-P – September 2007
Drive Thermal Cycle [Drv Thermal Cyc]
Linear Number: 772
Default Value: 600.0 sec
Minimum Value: 0.0 sec
Maximum Value: 6000.0 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the overload duty cycle for the drive. It is defined as the time interval after which
the drive could be subjected to its maximum overload capacity without exceeding the thermal ratings. The
default value is 600 seconds (10 minutes) which means that the drive is designed to handle 1 minute of
overload every 10 minutes. However for Banbury mixers and other heavy duty applications, the overload
cycle could be less than 10 minutes.
Drive Overload Trip [Drv OvrLoad Trp]
Linear Number: 163
Default Value: 1.15 pu
Minimum Value: 0.00 pu
Maximum Value: 4.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the maximum operating dc link current in the drive which will cause the drive to
trip on a drive overload fault after a time interval specified by parameter Drv OvrLoad Dly (164).
Drive Overload Delay [Drv OvrLoad Dly]
Linear Number: 164
Default Value: 60.0 sec
Minimum Value: 0.0 sec
Maximum Value: 600.0 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the time the drive will operate at the overload trip level Drv OvrLoad Trp (163)
before an overload fault is indicated.
Drive Overload Minimum [Drv OvrLoad Min]
Linear Number: 269
Default Value: 1.05 pu
Minimum Value: 0.00 pu
Maximum Value: 4.00 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the minimum per unit value of the dc link current which is regarded as an
overload condition. When the drive runs with a value less than the parameter setting, the overload
algorithm is not activated.
Line Neutral Voltage Trip [LineNeutVoltTrp]
Linear Number: 587
Default Value: 0.40 pu
Minimum Value: 0.00 pu
Maximum Value: 1.50 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the level the line neutral to ground voltage must exceed before a line neutral
over voltage fault is indicated.
