Faults And Alarms; Fault History - WEG CFW100 Programming Manual

10 FAULTS AND ALARMS

The problem detection structure in the inverter is based on the fault and alarm indication.
In case of fault, the locking the IGBTs and motor stop by inertia will occur.
The alarm works as a warning for the user of critical operating conditions and that may cause a fault if the situation
is not corrected.
Refer to Chapter 6 of the inverter user's manual and the PARAMETER, ALARMS AND FAULT QUICK REFERENCE
of the product to obtain more information on the faults and alarms.

10.1 FAULT HISTORY

The inverter is able to store a set of data on the last three faults occurred, such as: fault number, current (P003),
DC link voltage (P004), output frequency (P005), power module temperature (P030).
P048 - Present Alarm
P049 - Present Fault
Range: 0 to 999
Properties: ro
Description:
These parameters indicate the alarm (P048) or the fault (P049) number that may be present in the inverter.
P050 - Last Fault
P060 - Second Fault
P070 - Third Fault
Range: 0 to 999
Properties: ro
Description:
These parameters indicates the number of the occurred fault.
P051 - Current At Last Fault
Range: 0.0 to 40.0 A
Properties: ro
Description:
It indicates the output current at the moment of the last occurred fault.
P052 - DC Link At Last Fault
Range: 0 to 828 V
Properties: ro
