Abstract:
A control system, for a press machine including a plurality of die cushions, by which force control and position control may be suitably switched from one to another in each control device for each of the die cushions. The control system includes a plurality of control devices for controlling a servomotor of each die cushion and a switching signal generating part capable of collecting the judgment result of each control device. The switching signal generating part transmits a switching signal to each control device, in order to switch the control mode of each control device.
