Sub-trip Reason
0 Instantaneous trip when the d.c. link voltage exceeds the theshold in the table above
1 Reserved
2 Time delayed trip indicating that the d.c. link voltage is above VM_DC_VOLTAGE_SET[MAX].
Recommended actions:
Increase deceleration ramp rate parameter values.
Decrease the braking resistor value (staying above the minimum value).
Check nominal AC supply level.
Check for supply disturbances which could cause the DC bus level to rise.
Check motor insulation using an insulation tester.
Trip P.Dat
Value 220
Short description Configuration data failure
Data relevant to the rating of the drive is stored in the power stage processor flash memory. A copy of this data is also stored in the control board board processor and this is
transferred across at power up if the data in the control board and power stage does not match.. There ar a few sub-trips associated with power data transfer:
Sub-trip Reason
0 An error occured when writing to the data in the Power stage Flash (during factory upload of data)
1
A file error has been detected in the Power stage when data is being written to it (in the factory),or being uploaded from it by
the control board processor.
2
There is no table present in the power stage, or there is an error in the data table, or the control board is being powered from
the 24V backup supply and it does not have a valid table present (during 24V backup operation the control card cannot
communicate with the power stage to update the data dable).
3 The power system data table is bigger than the space available in the control pod to store it.
4 Reserved
5 Table CRC error.
6
The version number of the generator software that produced the table is too low, i.e. a table from a newer generator is required
that includes features that have been added to the table that may not be present.
7 The control board failed to upload the data from the power stage or write it to it's flash memory.
On size 5 and above the above sub-trips have 1000 added to them. i.e. sub-trip 1 will be displayed as 1001.
Recommended actions:
Hardware fault - contact the supplier of the drive.
Trip Pad
Value 34
Short description Keypad communication failure
If keypad reference mode is enabled (ReferenceSelectedIndicator (01.049) = 4 or 6) (i.e. ReferenceSelector (01.014) is set to 4 or 6 if motor map 1 is selected, or
M2ReferenceSelector (21.003) is set to 4 or 6 if motor map 2 is selected) and the keypad removed, then this trip is initiated.
Recommended actions:
Re-install keypad and reset.
Change ReferenceSelector (01.014) to select the reference from another source.
Trip Pb.bt
Value 245
Short description Power stage processor is in its boot loader
The power stage processor is in its bootloader
Recommended actions:
Send power stage firmware file to reprogram the power board and power cycle drive.
Trip Pb.Er
Value 93
Short description Communication link failure between Control board and power stage
