ACH550-01 User's Manual
Fault handling
The ACH550 indicates all faults in clear text and fault number in
the control panel (operator keypad) display. Refer to chapter
Diagnostics and maintenance
. Additionally, a fault code is
allocated to each fault name shown in parameters 0401, 0412
and 0413. The fieldbus-specific fault code is indicated as a
hexadecimal value coded according to the DRIVECOM
specification. Note that not all fieldbuses support the fault code
indication. The table below defines the fault codes for each fault
name.
