1) Encoder Steps parameter does not
match the actual motor encoder.
Set: Motor lost IFO control and
accelerated
without throttle command.
Clear:
Ensure the Encoder
Steps parameter matches the
actual encoder; cycle KSI.

1) The Motor_Type parameter value is
out of range.
Set: Motor_Type parameter is
set to an illegal value.
Clear: Set Motor_Type to
correct value and cycle KSI.

1) The VCL software in the controller
does not match the OS software in the
controller.
Set: VCL and OS software do
not match; when KSI cycles, a
check is made to verify that
they match and a fault is
issued when they do not.
Clear: Download the correct
VCL and OS software into the
controller.
