Fault Buffer Mechanism
The PROFIdrive profile has a mechanism that can store five fault situations to PROFIdrive
parameters. Fault and diagnostic data, like fault number and fault code, can be accessed
simultaneously with only one subindex. The mechanism consists of two PROFIdrive parameters:
•
PNU944: Fault message counter
•
PNU947: Fault numbers according to value in U02-01
Option High Priority Alarm Codes
These codes are transmitted as Manufacturer Specific Diagnostic high priority alarms that can be
seen in the PLC configuration software. These high priority codes are the same codes that appear in
the drive manual, except with an offset of 0x1000.
