Once could try to move the motor a99 % |Power| is not enough in most cases. One could try to move the motor a 100 100 % certain distance by using something like this: 101 101 … … 118 118 %% 119 119 % Now the motor will make exactly 1 whole turn and then stop at about 360 120 % degrees (accurate to +/- 1 degree atmost cases). It is very important to120 % degrees (accurate to +/- 1 degree in most cases). It is very important to 121 121 % understand that the motor does this movement "on its own", while MATLAB 122 122 % can execute the next command right away. If we say: … … 176 176 % * Use |'Brake'| mode (default) to let the motor(s) automatically 177 177 % slow down nice and smoothly just before the |TachoLimit|. This leads 178 % to a very high precision, usually the |TachoLimit| >is met within +/- 1178 % to a very high precision, usually the |TachoLimit| is met within +/- 1 179 179 % degree (depending on the motor load and speed of course). After this 180 180 % braking, power to the motor(s) is turned off when they are at
