 ===== Enable Signal =====
-On the Beaglebone blue we do not use a motor controller and therefore, we do not use this signal.

 ===== Ready Signal =====
+The ready signal signals to the controller that the motor controller has powered up. As there is no external motor controller on the Beaglebone blue we simply put this signal on a digital input pin which is connected to the on board push button //Mode//.
 ===== Emergency Signal =====
-Connect the encoder outputs (A/B signals) to the decoder inputs
-  * motor controller ready signal to a digital input
-  * emergency button to a digital input
-IMPORTANT Make sure that a positive voltage on the motor leads to the encoder counting upwards. If the opposite is the case, either change the cables or change the hardware configuration file. \\
-IMPORTANT On the beaglebone blue board, you don't need a motor controller. Hence, you do not need the enable signal. Tie the ready signal to logic one.
+The emergency signal is used to bring the application in a safe mode. We put this input signal on a digital input pin which is connected to the on board push button //Pause//. Later when the application runs we can cause the safety system to switch to an emergency state by pressing the //Pause// button.
