6.2 Standalone Operation 
 
The  

MD30C

can operate in standalone mode. In this mode, the motor is controlled by the

 

 

 

   

 

   

 

 

 

   

 

 

 

onboard switches and speed potentiometer. Alternatively, external switches and potentiometer

 

 

 

 

 

 

 

 

 

 

can be used to control the motor. This allow the switches and potentiometer to be mounted at

   

   

 

 

 

 

 

 

 

 

     

   

easy to reach place. 
 
 
Onboard Switches and Potentiometer 
 
Set the jumpers as below: 
JP4 :  INT POT 
JP6 :  INT PWM 
 
After that, connect the battery and motor to the MD30C. Pressing switch A will run the motor

 

 

 

 

 

 

   

 

 

 

   

 

 

 

 

in CW direction and pressing switch B will run the motor in CCW direction (The actual

 

 

 

 

 

   

 

 

 

   

 

 

 

 

direction is depending on the motor polarity). The speed of the motor can be controlled by the

   

   

 

 

 

 

   

 

 

   

   

 

onboard speed potentiometer. 
 

 

 
Don’t worry if the motor does not run when the switch is pressed. This might be due to the

 

   

 

 

 

 

 

 

 

   

 

 

   

   

 

speed is too low for the motor to run. Try turning the on board potentiometer CW (clock

   

 

 

 

 

   

 

 

 

 

 

 

 

 

 

wise) for a few round while pressing down one of the switch to increase the motor speed.
