The drive accurately tracks rotor position during fault conditions. For example,
if there is a "Low DC Bus" fault where the bridge is disabled, the drive will
continue to track the rotor's position provided the logic power is not
interrupted.
The CW/CCW Limit faults are automatically cleared when the fault condition
is removed. The table below lists all the fault codes in priority order from
highest to lowest. This means that if two faults are active, the higher priority
fault will be displayed.
