output profile.
•
Cleared (0) - Whenever a PTO instruction is not within the run
phase of the output profile.

•
Set (1) - Whenever a PTO instruction is within the acceleration
phase of the output profile.
•
Cleared (0) - Whenever a PTO instruction is not within the
acceleration phase of the output profile.
