ABSTRACT:
A brake time measurement and brake control system measures the brake time of a subassembly, such as an upper die of a press, with the programmable controller already used to control the press. The programmable controller has a selectable time interrupt which causes an interrupt routine inside the programmable controller to be executed at regular time intervals. By varying the duration of the interval, the precision of the brake time measurement may be varied. Also, since the system is implemented with the programmable controller already present on the press, no additional equipment is needed to measure brake time. The brake time monitor and brake control system also implements a top stop control capability with improved precision. The improved precision results from dynamically determining a top stop zone which is appropriately sized given the speed of the die. The improved precision also results from limiting the number of angles at which a stop command can be issued when the top stop zone is larger than necessary.
