AD-FMCMOTCON2-EBZ IIO User Guide
IIO OSC
ADI IIO oscilloscope is used for monitoring and controlling the AD-FMCMOTCON2-EBZ board, when using the Linux operating system. A complete user guide for the IIO oscilloscope can be found here.
Signals monitoring
The IIO Oscilloscope allows to monitor current, voltage, speed and control signals from the system. Below is presented a description of the different monitoring channels exposed by the IIO Oscilloscope.
| Group | Channel | Description |
|---|---|---|
| ad-mc-adc | voltage0 | Not used |
| voltage1 | Motor 1 Ia ADC raw data | |
| voltage2 | Motor 1 Ib ADC raw data | |
| voltage3 | Motor 1 VBus ADC raw data | |
| ad-mc-adc-m2 | voltage0 | Not used |
| voltage1 | Motor 2 Ia ADC raw data | |
| voltage2 | Motor 2 Ib ADC raw data | |
| voltage3 | Motor 2 VBus ADC raw data | |
| ad-mc-speed | voltage0 | Motor 1 speed. Number of counts in 10ns units between two motor commutations. In order to display the speed in RPM, the data should be processed by checking the 1/x option and multiply by 25.000.000 |
| ad-mc-speed-m2 | voltage0 | Motor 1 speed. Number of counts in 10ns units between two motor commutations. In order to display the speed in RPM, the data should be processed by checking the 1/x option and multiply by 25.000.000 |
| ad-mc-ctrl | Not used | |
| ad-mc-ctrl-m2 | Not used | |
Control
This dialog allows the control of the two motors in manual mode by directly specifying the fill factor of the PWM signals applied used to control the 3 phase inverters. The motors are driven using a 6 step comutation algorithm.
| Control | Description |
|---|---|
| Run | Starts the motor |
| Delta | Selects between driving the motor using a Star-like sequence or Delta sequence |
| Direction | Selects between clockwise and counterclockwise rotation directions |
| PWM | In Manual mode, the PWM can be set between 50% - 100% |
