Fault Handling

The MD5 provides fault information as follows:
• The control panel display shows a fault code and text .
See page 74 for a complete description .
• Parameters 0401 LAST FAULT, 0402 PREVIOUS
FAULT1 and 0403 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 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 .

Serial Communication Diagnostics

Besides the drive fault codes, the FBA module has diagnostic
tools . Refer to the user's manual supplied with the FBA
module .
