The drive must be in a disabled, stopped or tripped condition to allow default parameters
to be set. If default parameters are set while the drive is running, the display will flash
FAIL once before changing back to no.
With the 28C/29C variants, if defaults are loaded, these variants will have standard
parameter settings, not 28C/29C settings.
