Warnings do not need to be reset; they stop showing when the cause of the warning
ceases. Warnings do not latch and the drive will continue to operate the motor.
Faults do latch inside the drive and cause the drive to trip, and the motor stops.
After the cause of a fault has been removed, the fault can be reset from a selectable
source (parameter 31.11 Fault reset selection)), such as the control panel, the
Drive
Composer
PC tool, the digital inputs of the drive, or fieldbus. After the fault is
reset, the drive can be restarted.
Note that some faults require a reboot of the control unit either by switching the
power off and on, or using parameter 96.8 Control board boot – this is mentioned
in the fault listing wherever appropriate.
Warning and fault indications can be directed to a relay output or a digital
input/output by selecting Warning, Fault or Fault (-1) in the source selection
parameter. See the following sections:
• Programmable digital inputs and outputs (page 64)
• Programmable relay outputs (page 65), and
• Programmable I/O extensions (page 65).
￭
Pure events
In addition to warnings and faults, there are pure events that are only recorded in
the event logs of the drive. The codes of these events are included in the Warning,
fault and pure event messages table.
￭
Editable messages
For some warnings and faults, the message text can be edited and instructions
and contact information added. To edit these messages, choose Menu - Settings
- Edit texts on the control panel, or use the Localization editor in Drive Composer
pro.
Warning/fault history and analysis
￭
Event logs
The drive has two event logs. One log contains faults and fault resets; the other
contains warnings, pure events, and clearing entries. Each log contains the 64
most recent events with a time stamp and other information.
The logs can be accessed separately from the main Menu on the control panel. The
logs are displayed as a single list when viewed using the Drive Composer PC tool.
The logs can be cleared using parameter 96.51 Clear fault and event logger.
