Option High Priority Alarm Codes

Refer to the drive Technical Manual for details about each of the PROFINET Option High Priority Alarm Codes
(faults) listed in Table 8.19.
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 1000 (Hex).
