C Control PRO-BOT128 + C-Control PRO 128 Unit + Voltcraft® USB programming cable Kit 190406 Manuel D’Utilisation

Once the equipment of the PRO-BOT's circuit board is completed, you still have to attach the cables to the motor and fix them in place.

To connect the motors, you need a black and a red cable with a length of approx. 70 mm with stripped and tin-coated ends. If the enclosed cables
are not yet prepared properly, strip the ends and coat them by holding them to the tip of the soldering iron with a bit of solder. Cut off any solder
residue on the cable end with a side nipper.

Now solder the red cable to the motor connection marked with a red dot or a plus sign, and the black one to the other. The motor connection
cables for each motor are braided (not mandatory, but of advantage for electromagnetic compatibility and also looks a lot better).

The red connection cable of the left motor is soldered into "ML+" and the black one into "ML-", the red one of the right motor into "MR+" and the
black one into "MR-".

MR+ = motor right, "plus"

MR+ = motor left, "minus"

ML+ = motor left, "plus"

MR+ = motor right, "minus"

Finally the motors are attached to the circuit board. To do so, pull the cable clips through the holes next to the motors so that the heads of the
cable clips remain on the bottom of the circuit board and wrap the motors.

The finished transmission should look as follows after successful assembly (the gearwheels with the black and white stickers must be connected
to the short axis):

The gearwheels of the motors should not press down too hard on the larger gearwheel. There must be a bit of clearance here so that everything
rotates freely but the teeth do not skip.

? Once you have found the right position of the motors, you can protect them against shifting with a drop of hotmelt, for example.
