Trip
Out.P Output phase loss detected
The Out.P trip indicates that phase loss has been detected at the drive output.
Sub-trip
98
NOTE
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
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.

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
