A programmable motor controller block diagram

The block diagram of the programmable DC motor controller with a Liquid Crystal Display (LCD) can be imagined as a remote control box with two slide switches and an LCD, as shown in following diagram:

A programmable motor controller block diagram

The Remote Control Box provides the control signals to operate a DC motor. This box is not able to provide the right amount of electrical current to directly operate the DC motor. Therefore, a transistor motor driver circuit is needed. This circuit has sufficient current gain h_fe to operate a small DC motor. A typical hfe value of 100 is sufficient for the operation of a DC motor. The Enable slide switch is used to set the remote control box to the ready mode. The Program switch allows the DC motor to be set to an ON or OFF operating condition by using a simple selection sequence. The LCD displays the ON or OFF selection prompts that help you operate the DC motor. The remote control box diagram is shown in the next image.
