Abstract: A production system includes a cell control apparatus that is connected to a machine control apparatus and an inspection control apparatus. The cell control apparatus includes a storage part that stores data on a state of the manufacturing machine, data on an environment state, and data on an inspection result of a product. The cell control apparatus includes a correlation analysis part that selects a variable relating to an abnormality based on a correlation between the inspection result of the product, and the data on the state of the manufacturing machine and the data on the environment state when the abnormality occurs in the inspection result, and a determination value setting part that sets a determination value of the variable relating to the abnormality.

Abstract: A motor drive according to the present invention has a dynamic braking circuit. The motor drive includes a motor drive control circuit for applying a voltage to windings of a synchronous motor and the dynamic braking circuit for a predetermined time by switching power transistors connected to a direct current power supply, a current detection circuit for detecting a current value outputted from the power transistor, and a failure determination circuit for determining the presence or absence of a failure in the dynamic braking circuit from the current value detected by the current detection circuit and a predetermined threshold value. When the presence or absence of a failure in the dynamic braking circuit is detected, the resistance of the dynamic braking circuit is changed.
