We have reviewed the contents of this publication to ensure consistency with the hardware and software described. Since variance cannot be precluded entirely, we cannot guarantee full consistency. However, the information in this publication is reviewed regularly and any necessary corrections are included in subsequent editions. Using an example of a conveyor belt, we will illustrate how easy it is to control a drive motor with an S You will use the S to start the motor, switch the direction of rotation, and then stop the motor again.

The example will take approximately 1 hour to implement, depending on your prior knowledge. Serious bodily injury and damage to machinery and equipment can occur if you do not observe the safety and accident prevention regulations, e.

Operation of an S in plants or systems is governed by special rules and regulations, depending on the specific field of application. In order to install the conveyor belt control, you will need the following materials and tools:.

CPU C with an extra-low voltage that is safely isolated from the supply system. If the CD does not start up automatically, you can start the setup program by doubleclicking the Setup.

Configure the connection to the USB interface. Next, you will install the control components on the mounting rail. If you do not have a motor, you can still implement the example.

Screw the mounting rail to the subsurface. Use two M6 screws for this. Connect the mounting rail to the ground wire. The prescribed minimum cross-section for the cable to the protective conductor is 10 mm 2.

This is needed to satisfy the requirements for thermal conditions heat dissipation and ventilation of the module and to facilitate the installation mounting and removing, wiring. This produces a uniform reference potential. Insert the front panel connector into the CPU C until it engages.

The front panel connector still protrudes from the module in this wiring position, and is not yet connected to the module. This position makes it easier for you to complete the wiring. Welcome to ManualMachine.
