 The Pressure Die Retract Timer [[COMDEF]] command can open the pressure die a small distance and simultaneously send the [[clamp die]] home.  The command is considered complete when the pressure die has arrived at its timed destination.  The next step is often for a Post Bend Jog (which is a bend die clearance move for non split-die benders).
