The 1065 lets you control the direction, velocity
and acceleration of one DC Motor. The motor is powered by an external
power supply (9 to 28VDC).
Brushed DC Motors are very simple to understand, but very difficult
to control precisely. By applying a voltage, or pulsing a voltage
rapidly, at the terminals of the motor, current flows through the
motor, and it will begin rotating. Depending on the direction of the
current, the motor will rotate clockwise or counterclockwise. The
1065 changes the effective voltage by changing the percentage of time
the full supply voltage is applied to the motor. By switching the
voltage very quickly (a technique called PWM), the controller is made
smaller, more efficient, and cheaper.
Rough control of actual motor speed can be achieved automatically
in software by using the Back EMF property, or current sensing.
Precise control of DC motors can be achieved by using encoders. You
can implement control loops through software by using the data provided
by the on-board digital inputs, analog inputs and encoder input. There
is an event that triggers every 16 ms that returns the back-EMF value
for the attached motor, which can be very useful for PID control.
For more information, see the API in the User Guide.
The 1065 also provides over-current, over-voltage, and over-temperature
protection to insure that the board and motor is not damaged.
