Together with current sensing capability, the AEK-MOT-2DC40Y1 features three independent encoder inputs. The DC motor drivers have separate half-bridge driving which allows up to three separated motors with only two devices, using an appropriate driving sequence. The motor driver is ideal for two-wheel applications and allows engineers to build highly compact motor control solutions. The two high-side drivers facilitate additional driving for system actuators (unidirectional DC motor, LED, pump, etc.).

The dedicated GUI allows intuitive management of three motors directly connected to the VNHxxx devices (MOTOR 1, MOTOR 3, MOTOR 5). For each motor, it is possible to set rotation direction and to connect an encoder for precise positioning. MOTOR / LOAD 2 and MOTOR / LOAD 4 are connected on the VNxxx devices and are therefore they are unidirectionally driven. MOTOR 1, MOTOR / LOAD 2, MOTOR 3, MOTOR / LOAD 4 can be driven in parallel, while MOTOR 5 should be activated separately to avoid improper driving on MOTOR 1 and MOTOR 3. AutoDevKit high-level drivers are very straightforward and comprehensive API support is available through online help in SPC5Studio. The user can invoke the desired functions such as starting a DC motor, increasing or decreasing the DC rotation speed, and braking by just passing the motor parameter (e.g., MOTOR 1) to them. The API set includes diagnostic functions indicating if the device is in Fault or in Operative mode. Moreover, it is possible to monitor the device even when it is switched off, to avoid starting the application while faults are present. Inside AutoDevKit plugin, there are several examples of API usage, including one using an encoder. The encoder has a ‘K’ factor that should be set in the appropriate #DEFINE in the encoder driver according to the specific motor model. The AutoDevKit also allows you to implement custom PID control, useful for negative feedback systems, by modifying the relevant #DEFINE statements in the PID driver code.
