WUEKRO Technology Simulators Sequential controls Sequential control is the control of a sequence of operations in individual steps. Switching from one step to the following step is controlled by the control program in accordance with the “step enabling conditions”. The main property of the sequential control is that it can clearly assign individual steps to technological procedures with respect to time and function. Consequently, distinction is made between “time-oriented” and “process-oriented” sequence control. Positioning control technology simulator Pieces of wood are cut true to dimensions on a saw table. For this purpose a stop is to be positioned from a control console with the help of an electric motor. The movement of the stop is measured with a shaft-angle encoder. Limit switches are located at the end position of the spindle, which are to prevent the stop from entering the restricted area. Prior to restart and cold restart of the installation, the reference point is to be approached. The spindle drive can be controlled in clockwise or Two-door access control system technology simulator A dust-free room can be entered or left only through an air-lock with two automatically opening and closing doors. Light barriers monitor the entrances. In the case of an emergency the air-lock room can be opened or closed from within using additional door openers. Limit switches indicate the corresponding positions of the doors. All operating states are to be indicated via LEDs. Page 10 counter-clockwise rotation and also with creep speed.
