Many operations require very low power to be managed effectively. Consider the operation of a roller shutter, the homokinetic joint developed by FET, etc. For this reason, a generic 12V motor control circuit has been developed with a nominal voltage and current below 2 amps. This compact-sized module can be housed near the motor to be controlled and operated via a CAN communication line.

To have complete control, envisioning the management of a generic operation, at least two limit switches and a digital encoder are needed to detect ongoing movement, velocity, and calculate relative position. Additionally, the module includes measurement of the current drawn by the motor and the system voltage.

Movement commands are transmitted via the CAN line, essentially consisting of the number of steps for right or left displacement or continuous movement in both directions. Status information, including position, limit switches, power consumption, and potentially energy consumed over a certain period or for a specific movement, is exchanged via CAN. Alternatively, local operation is possible with the activation of right and left movement commands.
