Abstract: An arrangement for automatically providing data for controlling a die casting machine that would otherwise have to be entered by an operator each time a mold of the die casting machine is changed. In a first embodiment, the operator inputs only data indicating which mold is to be used and the appropriate operational data is retrieved and sent to the die casting machine. In a second embodiment, the identification of the mold is handled automatically, to totally eliminate the need for an operator to input data.

Abstract: A setting unit sets data indicative of a normal shot operation of the die casting machine and a detection unit detects the operational status of the machine. A distinction unit distinguishes the coincidence of both the setting data and detected data. If the detected data are substantially equal to the setting data then the distinction unit sends a coincidence signal. A counting unit counts the coincidence signals of an injection process.

Abstract: A moving component of a robot, such as a robot arm, is controlled to return from a given position to an original point after the moving component has traced paths established respectively by a group of successive motion data blocks including positional data representative of positions of the moving component. The moving component is moved on the basis of positional data in one of the motion data blocks which precedes a present position of the moving component, and then is moved on the basis of positional data in one of the motion data blocks which precedes said first-mentioned one of the motion data blocks. Therefore, the moving component is moved successively backwards along the paths based on the positional data in the motion data blocks.
