Fault handling
The ACQ550 provides fault information as follows:
• The control panel display shows a fault code and text. See chapter Diagnostics
on page 251 for a complete description.
• Parameters 0401
LAST FAULT, 0412 PREVIOUS FAULT1 and 0413 PREVIOUS FAULT2
store the most recent faults.
• For fieldbus access, the drive reports faults as a hexadecimal value, assigned
and coded according to the DRIVECOM specification. See the table below. Not all
profiles support requesting fault codes using this specification. For profiles that
support this specification, the profile documentation defines the proper fault
request process.
