Application Hardware and Software Configuration

6.4.4.1 Manual Operating Mode

In the manual operating mode, the drive is controlled by the RUN/STOP switch and the required speed is set by the SPEED potentiometer. The RUN/STOP switch enables/disables motor spinning. The yellow LED will light whenever the application software correctly executes (so, it will also light when motor spinning is disabled or at a fault state).

•When motor spinning is enabled and starts spinning (alignment or starting/back-EMF acquisition state), only the yellow LED lights.

•When motor rotation is enabled and the motor runs with speed closed loop (running state), the green LED lights (yellow LED also lights).

•If an over-current or over-voltage fault occurs, the internal fault logic is asserted and the application enters a fault state indicated by a red LED blinking (yellow LED lights).This state can be exited only by an application RESET or setting RUN/STOP switch to STOP.

NOTE: It is strongly recommended that you inspect the entire application to locate the source of the fault, before starting again.

6.4.4.2 PC Master Software (Remote) Operating Mode

In the PC master software (remote) operating mode, the drive is controlled remotely from a PC through the serial communication interface (SCI) channel of the MCU device via an RS-232 physical interface. The drive is enabled by the RUN/STOP switch, which can be used to safely stop the application at any time.

For the PC master software (remote) control it is necessary to have PC master software installed on your PC computer!

Start the PC master software application:

After you start the PC master software, press “control page” to make the control window visible! Figure 6-6illustrates the PC master software Control Window.
