Fault Buffer Mechanism
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 U2-01

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.
