Fault/Warning Handling The lights on the motor control board indicate the status of the Current and
Velocity processors. Both the Current and Velocity processors have both
Green and Red LED’s associated with their status. Table 6.C explains the
meaning of the CP and VP status lights.

Hard Fault – A Drive hard fault is a fault that trips the Drive causing it to
come to a stop. This type of fault requires the user to perform a Drive
Reset to remove the fault.
Soft Fault – A Drive soft fault will also cause the drive to trip and come
to a stop. This type of fault can be removed by doing a Clear Faults
command after the condition that caused the Drive to trip has been
removed.
Drive Warning – A Drive Warning is simply an undesirable condition
that exists within the Drive. It will not cause the Drive to trip. A Clear
Faults command after the warning condition has been alleviated, will
remove the warning.
Everytime the Drive has any of the faults or warnings decribed above, a
fault/warning message is logged in either the fault or warning queue. This
is designed to aid in troubleshooting.
Motor Control Board Faults & Warnings – There are two types of fault
and warning queues for the Main Control Board, configurable and
nonconfigurable.
Configurable Faults & Warnings – The configurable fault queue
contains faults that can be set up to either trip the drive or provide only a
visual warning while the drive continues to operate.
Nonconfigurable Faults & Warnings – The nonconfigurable fault queue
contains faults that you can’t disable. These faults are the result of a
condition that could damage the Drive if allowed to persist. The non –
configurable fault queue faults can be viewed in parameter 81 (Fig. 6.2).
In addition to configurable & non–configurable faults, there are the
“powerup faults”.
Powerup Faults – The powerup faults appear in parameter 80 (Fig. 6.3).
These faults primarily consist of problems that could occur with powerup
of both the current and velocity processors.
Adapter Board Faults – Adapter board faults are setup and displayed in
separate parameters from the Main Control Board.
