Example of Fatal Error Crash
Fatal Error
Indicates the nature of the crash.
Please Report
A fatal error should always be reported to Merrick Technical Support.
The last line normally will contain additional information. I this example, an attempt was
made to perform a division with a zero value in the denominator.
The most common reason is that an invalid parameter has been entered into the
controller by means of serial communications or by using the Register Editor. If you have
been working with communications or using the register editor recently, you may have an
idea of what happened.
The only way out of this situation is to cycle the MC³ power. This may restore controller
operation, but the most likely scenario you will see a new Crash Screen at controller
boot. If that is the case, you can attempt forcing a Reset to Factory Default, and then re-
enter all controller parameters. See below.
