Fault Type(s): 1
This occurs if a controller is
commanded to reset while controlling
a PMAC motor that is not stationary.
Examples of resets include sending
an NMT reset or calling reset_
controller() in VCL.
Note, the controller will NOT reset
when safe unless the NMT is resent
or reset_controller() is called again.
If legacy brownout is set to off,
the user may see this fault if the
controller is turned off and on again
at an unsafe time, but in this instance
the controller will reset as soon as
it is safe to do so. Consult Curtis
Support for further assistance using
non legacy brownout.
Set: A reset was called at a
time unsafe for the controller.
Clear: Cycle KSI.

1. Controller is operating in an
extreme environment.
2. Excessive load on vehicle.
3. Improper mounting of
controller which is preventing
controller cooling.
4. Controller is performance-limited
at this temperature.
5. See Programmer » System Monitor
menu » Controller » Temperature.
Set: Controller’s heatsink
temperature exceeded 85°C.
Clear: Bring heatsink
temperature below 85°C.
Reduced drive torque.
