9.3 Fault and Warning Messages
9.3.1 Fault and warning messages AKD
When a fault occurs, the drive fault relay is opened, the output stage is switched off (motor
loses all torque), or the load is dynamically braked. The specific drive behavior depends on
the type of fault. The LED display on the front panel of the drive shows the number of the fault
that occurred. If a warning is issued prior to the fault, the warning is shown on the LED and
has the same number as the associated fault. Warnings do not trip the power stage of the
drive or fault relay output.
The left side of the LED displays F (or E) for a fault or n for a warning. The right side displays
the fault or warning number as follows: 1-0-1-[break]. The highest priority fault is displayed.
Multiple faults may be present when a fault condition is occurring. Check the AKD
WorkBench Fault Screen or read the status of DRV.FAULTS through the controller or HMI
for the entire list of faults.
Eliminate errors and faults in compliance with work safety rules. Troubleshooting only by
qualified and trained staff.
More information about fault messages, remedy and clearing faults can be found in the
WorkBench online help and in KDN.
