10.6 Output Flags
Output ags are symbols that are encountered on the left hand side of the assignment "="
operator. They direct the result of the input expression towards an output purpose.
Output ags are identied by <variable>_O.
Output ags represent items such as:
• digital outputs
• system control switches.
Perfect Harmony drives have a set of pre-dened symbols that describe control outputs or
"switches" that can be controlled by the SOP. These switches can control functions such as the
source of the speed reference, a selection for the system acceleration rate and many more. In
most cases, to cause the system to perform in the intended manner, the proper control switches
must be set, and others cleared, by the SOP.
