Out.P
Output phase loss detected
98
The
Out.P
trip indicates that phase loss has been detected at the drive output.
If Pr
05.042
= 1, the physical output phases are reversed, and so sub-trip 3 refers to physical output phase V and sub-trip 2
refers to physical output phase W.
Recommended actions:
•
Check motor and drive connections
•
To disable the trip set
Output Phase Loss Detection Enable
(06.059) = 0
OV
DC bus voltage has exceeded the peak level or maximum continuous level for 15 seconds
2
The
OV
trip indicates that the DC bus voltage has exceeded the VM_DC_VOLTAGE[MAX] or
VM_DC_VOLTAGE_SET[MAX] for 15 s. The trip threshold varies depending on voltage rating of the drive as shown below.
Sub-trip Identification
Recommended actions:
•
Increase deceleration ramp (Pr
00.004
)
•
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 to rise
•
Check motor insulation using an insulation tester
Trip
Diagnosis
Sub-trip
Reason
1
U phase detected as disconnected when drive enabled to run.
2
V phase detected as disconnected when drive enabled to run.
3
W phase detected as disconnected when drive enabled to run.
4
The drive output frequency is above 4 Hz and a phase is disconnected for the time
specified by
Output Phase Loss Detection Time
(06.058).
