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 tow 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.

 Manual Control

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%
