The drive event flags indicate certain actions have occurred within the drive as described below.
Defaults loaded (Bit 0)
The drive sets bit 0 when defaults have been loaded and the associated parameter save has been completed. The drive does not reset this flag
except at power-up. This flag is intended to be used by SM-Applications option module programs to determine when the default loading process is
complete. For example an application may require defaults that are different from the standard drive defaults. These may be loaded and another
parameter save initiated by the SM-Applications module when this flag is set. The flag should then be cleared so that the next event can be detected.

Pr 6.42 and Pr 6.43 provide a method of controlling the sequencer inputs and other functions directly from a single control word. If Pr 6.43 = 0 the
control word has no effect, if Pr 6.43 = 1 the control word is enabled. Each bit of the control word corresponds to a sequencing bit or function as
shown below.
