# Initiating FLUSH mechanisms

During communication with an external tool management, there may be waiting times for processing during T and D programming for synchronisation reasons. Due to the buffering of the NC channel a number of motion-related NC blocks can be held back before these commands, i.e. execution of the movement is also delayed. The execution of the delayed motion blocks can be forced by configuring implicit FLUSH mechanisms.
