3 Overview

The isolated inverter (enhanced protection) platform is a power board that runs from a dc input in the

range (24-800Vdc) and provides a three-phase variable frequency, variable voltage, and variable dead-

time PWM output to a motor or load. The inverter is provided as an open loop platform with no

feedback loops – however these can be added by the application developer. Isolated current and voltage

feedback are provided to the control side of the board via sigma-delta modulators (AD7403), and these

can be used for development of sensor-less control algorithms. The inverter is made up of a three-phase

six-IGBT bridge, with the IGBTs rated at 1200V and driven by six isolated gate drivers (ADuM4135).

A DC – rather than AC- input is provided to allow flexibility on the dc bus voltage level (rather than it

being limited to the ac line peak).

This document will give a high level introduction to the EV-MCS-ISOINVEP isolated inverter platform

and will provide a step-by-step approach that will get a motor/load up running with the platform and an

ADSP-CM408 EZkit, although the platform can be controlled from any variable frequency PWM

source. Instructions are provided on hardware setup, executable download, IAR project building and

graphical user interface (GUI) operation.

3.1 System requirements

Before you start working on the inverter platform, please make sure you have the hardware and

software listed below.

Required Hardware

- ADSP-CM408F EZ-KIT rev 0.2 (This is ordered separately from the EV-MCS-ISOINVEP-Z)

- EV-MCS-ISOINVEP-Z power board, including the provided control power supply and adapter

board (for connection to EZkit)

- Power board supply (not provided). The board is optimized to work from a DC supply in the

range 24Vdc-800Vdc. The power rating of the supply should be sufficient to match the load

being driven. The power board is rated up to 2kVA. There is a series connected diode in the

input, so if needed, the power board can be driven from an ac supply. However output power is

limited in this case.

- If a Segger J-Link Lite debugger is not available (although this is automatically provided with

an ADSP-CM408 EZ-KIT) a USB to serial converter (not provided) is required to download

executable demo code to the EZ-KIT. A USB to serial converter is also required if the user

wishes to visualize data variables using the Graphical User Interface (GUI).

Optional Hardware

- A three-phase load is strictly speaking, optional, however in order to evaluate the inverter

components it is more useful to have current flowing to an output. This load will typically be a

three-phase motor, such as an induction motor or permanent magnet synchronous motor, but a

three-phase, three-wire resistive load can also be connected. This is not supplied with the board.

Protection) Platform

Rev. 0.2

ANALOG DEVICES Page 5

- Segger J-Link Lite debugger (This comes with the ADSP-CM408F Ezkit and can be used for

executable download, and code development, but is not necessary for basic setup)

- If a full AC front-end is required, the inverter platform can be utilized in conjunction with the

ADP1047 evaluation board up to 300W, or the ADP1048 evaluation board up to 600W (see

http://www.analog.com/en/power-management/digital-power-

management/adp1047/products/EVAL-ADP1047/eb.html and

http://www.analog.com/en/power-management/digital-power-

management/adp1048/products/EVAL-ADP1048/eb.html )

Required Software

- ADSP-CM40x SW Enablement Package version 2.0.0 (available here :

https://ez.analog.com/docs/DOC-12607 )

- Inverter demo program executable and linker map file (available here:

https://ez.analog.com/docs/DOC-12608 ) for ADSP-CM408 Silicon Rev 0.0 only.

Optional Software

- ADIMonitor Graphical User Interface (also available here: https://ez.analog.com/docs/DOC-

12608)

- IAR Embedded W orkbench (for code development, version 7.4 or higher)

- Segger J-Link Lite driver software (v4.97j or higher)

- IAR Embedded Workbench inverter demo program C project (also available here:

https://ez.analog.com/docs/DOC-12608 ) for ADSP-CM408 Silicon Rev0.0 or Rev H.

4 Hardware Setup

This section will describe how to setup the hardware for a demo motor control application. This only

has to be performed once, when bringing up a new platform. The application is designed to spin a

three-phase motor in open loop Volts/Hertz control. The control settings are matched to a typical 2-pole

induction motor; however other motors will also spin, but the speed reference may not match the actual

speed of the motor if the pole count is different.

Connect the EZ-kit to the adapter board and the adapter board to the power board as shown in Figure 1.

Figure 1 Inverter Board connected to CM408F EZ-kit.

Ensure that the Motor/Load and Power Connectors are wired as shown in Figure 2, Table 1 and Table

2. As noted previously, the three-phase load can be a resistor bank or a three-phase motor. The power

board is designed to operate from a DC bus supply but can also be run from AC with limited output

power.

Plug in the power adapter to connector J3 to provide the control power supply to the boards. Do not

plug in the ADSP-CM408 EZkit. It derives its power supply from the inverter board. However, JP2

jumper must be set on the EZkit to enable “5V_INPUT” rather than “WALL_POWER”; see Figure 3.

Figure 3 Control Power Supply Input and Power Select Jumper

There are four sigma-delta modulators which provide isolated current and voltage measurement or

feedback. The precision and group delays of these signals are controlled by the setup of the digital filter

parameters used in the software. The default configuration on the board is for the following signals to

be measured:

 U phase motor current

 V phase motor current

 W phase motor current

 DC bus voltage

There is additional optional feedback of the UV and VW line to line motor voltages. These can be

exchanged for the DC bus voltage measurement and W phase current measurement by removing R69,

R66, R240 and R241 zero ohm resistors, and populating R176, R177, R67 and R81 with zero ohm

resistors.

5 Software Setup

The software setup steps are as follows:

1. Download and install the ADSP-CM40x SW Enablement Package from the link shown

previously in “SW Requirements”. This includes the serial boot-loader which is needed for

download of the executable to the processor.

Power Select

Jumper

Rev. 0.2

ANALOG DEVICES Page 9

2. Download and install the GUI from the Engineer Zone link provided in “SW Requirements”.

This requires the .NET framework to be on the PC and it will prompt the user to download this

if it is not detected.

3. For ADSP-CM408 silicon version 0.0 (see processor face for silicon versions), method (a) or

method (b) can be used. For silicon version H, currently only method (b) can be used.

(a) Download the inverter demo executable program from the Engineer Zone link provided in

“SW Requirements” and program this to the processor board (ADSP-CM408 EZkit)

(b) Compile and download the C code demo project from the Engineer Zone link provided in

“Optional Software”.

The first two steps are fairly self-explanatory. Step 3(a) – programming of the executable to the

processor – can be carried out in two alternate ways. These are detailed in Section 5.1 and Section 5.2.

Step 3(b) – compile and download from IAR Embedded Workbench – is outlined in Section 5.3.

5.1 Programming with Serial Downloader

The serial downloader (“wsd.exe”) is provided as part of the ADSP-CM408 SW Enablement Package

and once this has been installed, assuming default installation directory structures, the downloader is

found in C:\Analog Devices\ADSP-CM40x\CM403F_CM408F_EZ-KIT\tool\UARTFlashProgrammer.

This method uses the MC_Demo.hex executable provided at the Engineer Zone link.

Steps:

1. Connect the EZ-kit to the PC using the USB-UART cable: UART (RS-232) connector on the

EZkit, USB on the PC

2. Select Boot Mode 3 (UART Boot) on the EZkit using the selector switch P3 (adjacent to the

power connector)

3. Power up the EZkit

4. Open the Windows Serial Downloader (wsd.exe) and select the appropriate options:

Target: ADSP-CM40x (flash)

Serial Port: Select the COM port to which the USB-serial cable is connected (if in doubt,

check under ‘Device Manager->Ports’

Baudrate: 115200

5. Click "Browse" under "File to download" and navigate to the provided executable

“MC_demo.hex”

6. Select "Start"

7. Once the operation completes, select Boot Mode 1 (SPI Flash Boot) on the EZkit, using the

selector switch P3 (adjacent to the power connector)

8. Reset the EZkit (SW2 adjacent to power connector)

At this point the application should now be executing or loaded from flash, and the GUI can be

connected to run the motor.

5.2 Programming with Segger J-Link

This method uses the JLink software and the debugger provided with the EZkit to program the

processor flash memory.

1. Download and install Segger JLink Software ( http://www.segger.com/jlink-software.html)

2. Click the blue download button under Windows. The version number may be different from

the one shown below.

3. Enter your Segger JLink Lite serial number in the next box. This number is printed on the

microcontroller on the debugger board.

4. Click the confirmation box on the next screen, download the software and install (default

location is C:\Program Files(x86)\Segger)

5. Connect the JLink to the PC USB port and the other end to the 20 pin connector on the

CM40x board.

6. The PC will start automatically start installing drivers for your Jlink . Let it complete and

turn on power to the EZkit.

7. Turn on power to the CM408x board.

8. Go to the location where Segger was installed and click on JLink .exe. In this case it is in:

C:\Program Files (x86)\SEGGER\JLink_V490 (The version number and folder name may

be different to the one in this example.)

9. The following should be displayed in the Jlink window. It should identify that a Cortex-M4

is connected to the Jlink .

Rev. 0.2

ANALOG DEVICES Page 12

1. Enter the following at the prompt:

exec device = ADSP-CM408BSWZ-BF

The following will be displayed indicating that the chip has been identified correctly:

2. Copy the binary file you need to load into the CM40x in a known location. For this example, we

will be placing the file MC_demo.bin in C:\temp

3. In the JLink window, type the following to load the binary code at address 0x1800 0000, which

is the start of flash.

loadbin c:\temp\MC_demo.bin, 0x18000000

A new window pops up, indicating progress:

The JLink window will also show information about the flash procedure.

Rev. 0.2

ANALOG DEVICES Page 13

4. Reset the EZkit (SW2 adjacent to power connector)

At this point the application should now be executing or loaded from flash.

5.3 Compile and Download from IAR Embedded Workbench

First, get the C code demo project from the relevant Engineer Zone link and copy it to a local disk

drive. The path of the MC project will be referenced as $MC_DIR$ in the following. For example,

MC_DIR could be “C:\CM408Demo\”

Before proceeding, ensure that the ADSP-CM40x SW Enablement package has been downloaded and

installed as mentioned previously. Follow the instruction given during the installation.

To prepare the IAR Embedded Workbench environment, follow the steps below.

1. Open $MC_DIR$\SW\IARProjects\IsoInv_VF\iar\IsoInv_VF.eww in IAR EWB (Open

Workspace)

2. Go to “Project→Options→General Options→Target” and ensure that a floating point unit (FPU)

is selected. In the “Library Configuration” tab, ensure that “Use CMSIS” is selected.

3. Go to “Project→Options→C/C++ Compiler→Preprocessor→Define Symbols”, see Figure 4 and

check that the correct additional include libraries and pre-compiler options are selected for the

demo platform used. Possible configurations for the preprocessor defines are shown in Table 3.

The additional include libraries are:

C:\Analog Devices\ADSP-CM40x\CM403F_CM408F_EZ-KIT\inc

C:\Analog Devices\ADSP-CM40x\CM403F_CM408F_EZ-KIT\inc\sys

4. Ensure that the linker library files are listed as shown in Figure 5 and that the Linker

configuration file in the Linker->Config tab is set to

$PROJ_DIR$\CM40z_384_2048_copy_to_SRAM.icf.

Figure 4: Include Directories and Preprocessor Defines

The IAR project can now be built.

1. Open $MC_DIR$\SW\IARProjects\PMSM_FOC\iar\pmsm_foc.eww in IAR EWB (Open

Workspace)

2. Click Project→Rebuild All

3. Build/link status can be obtained from the message window.

In its default configuration the Motor Control Demo rev 0.3.0 is set up to work with silicon rev. 0.0.

However, with minor adjustments, silicon rev H is also supported. (Note: The silicon revision is indicated

on the processor face). Silicon rev. H adds a Boot-ROM-based secure access protocol that imposes specific

software requirements which must be met for successful booting. IAR-based application project files

targeting silicon rev 0.0 should DEFINE the compiler preprocessor symbol

“ADI_NO_SECURITY_PROTOCOL” in startup.c to circumvent security protocol code generation. Project

files targeting silicon rev H should REMOVE the compiler preprocessor symbol

“ADI_NO_SECURITY_PROTOCOL”.

With rev H silicon, the code in startup.c should look like this:

// #define ADI_NO_SECURITY_PROTOCOL

For further information, please refer to”ADSP-CM40X ENABLEMENT SOFTWARE USER'S GUIDE”.

With the linker file (.icf file) supplied with the demo project, CM40x boots from flash and then loads

all code into SRAM and executes code from SRAM. In this mode it is only necessary to program

memory when the program is changed.

To program the device, follow the steps below

Quick Start Guide for EV-MCS-ISOINVEP-Z Isolated Inverter (Enhanced

Protection) Platform

Rev. 0.2

ANALOG DEVICES Page 16

1. Connect Segger J-Link debugger between a USB port on the PC and the Debug connector on

the EZ-kit

2. Turn on the 5V power supply to the EZ-kit.

3. Go to IAR EWB and download program to target by clicking Project→Download and Debug

4. In IAR EWB, start the program by clicking Debug→Go

Once Flash has been programmed, Flash boot runs stand-alone and does not require IAR

EWB+debugger.

6 Manual Mode

The board can also be run in manual mode with control of output frequency and dead-time being

implemented from the dials on the board, and with no need of a PC connection to the EZkit. The

system will run with default parameters, and the GUI can still be used for data visualization. However

it should not be used for control in manual mode, as the control inputs may conflict with the manual

inputs.

The steps to be followed for running the platform in manual mode are as follows:

1. Plug in the 12V control power supply

2. Set the mode selector switch to Manual

3. Set the Start/Stop switch to Stop

4. Reset the EZkit

5. Ensure no fault LEDs are showing

6. Turn on the DC bus power

7. Set the Start/Stop switch to Start

8. Control motor speed/load voltage and frequency with the Frequency dial, and control PWM

dead time with the Dead Time dial

A Safe Torque Off (STO) fault or shutdown can be emulated by shorting the jumper JP1. This will

remove power to the gate drivers, and trigger a PWM fault in the processor. Removing the short and

resetting the fault status by means of the momentary switch SW4 will cause the power board to restore

power to the motor and ramp up the output PWM to its previous operating point (unless the Start/Stop

button has been set to Stop in the meantime).

The LEDs can provide some level of diagnostics as to power supply busses and fault conditions. It

should be noted that if the EZkit is reset, the frequency and dead-time settings revert to their default

start-up values (zero PWM output, and 1s dead-time), i.e. the dials are not absolute position related.

The dead-time range allowed is 500ns to 20s.

7 GUI Mode

Once the installation zip file is extracted, the GUI application is loaded by running the installer executable

“ADIMonitorGUI.exe”. This GUI requires the .NET framework and this will be downloaded if it is not

already on the PC. The first step is to set up the serial port (having connected the USB-serial converter

to the EZkit RS232 port). This is accomplished by right-clicking the bottom right-hand corner of the GUI

and selecting Connect. The program should automatically select the correct COM port, but if several

options are available, right-click Configure and select the correct one. Once this is selected press, Save

and then Connect.

Figure 6: Serial Port Setup

The next step is to configure the motor control settings. These are listed in Table 4, along with an

explanation of their relevance. These settings are designed for open loop Volts/Hz control of a 2-pole

motor. If a different number of poles is utilized, the system will still work, but the rpm to Hertz correlation

will be incorrect.

Once the configuration settings have been entered, press Configure. Typical settings for open loop control

Rev. 0.2

ANALOG DEVICES Page 18

volts/Hz or volts quantities. Care should be taken when setting the VF_GAIN quantity. If it is set too

high, the motor will draw large currents and an overcurrent trip may occur, especially if a permanent

magnet synchronous motor is being used. Also if the VF_MAX_RATE is set too high, the applied motor

voltage and frequency will ramp too quickly – especially if a large step change in speed reference occurs

– potentially causing an overcurrent trip. If an overcurrent or PWM trip occurs, or an STO trip is created,

press the GUI Reset Trip button (Figure 8) and then Stop. Reduce VF_GAIN or VF_MAX_RATE to

limit the steady state and transient current amplitudes if necessary and re-start the motor. The fault LEDs

should clear when the Reset Trip command is pressed.

Figure 7: Motor Control Configuration – Typical open loop settings.

8 Running the Motor

In order to control the motor, navigate to the Control and Monitor tab. From here, the motor can be

started by pressing the Start button, and the speed varied by moving the slider or entering a speed in the

numeric box. Dead time can also be varied by moving the slider or entering a ns value in the numeric

box. This is illustrated in Figure 8.

9 Data Visualization

In order to import visualization data into the GUI, the linker map file (MC_demo.map) provided with

the demo C code or executable must be loaded. This is selected from the Configure tab as illustrated in

Figure 9 with the resultant variable list shown in Figure 10. The variables provided by default have a

UID_ prefix in the map file and are listed in the Table below, along with their data types. It should be

noted that the GUI cannot determine from the map file if a variable has signed or unsigned type, so if a

variable is of signed type (e.g. duty_a) it is necessary to manually change the Type from UINT16 to

SINT16 in the relevant column of Figure 10.

Figure 10: Visualization Variables

In order to select a variable for plotting, selection is by means of the check-box in the Plot column. The

variable can be plotted in Plot 1 or Plot 2 (see Figure 8). There are certain constraints on the number of

Quick Start Guide for EV-MCS-ISOINVEP-Z Isolated Inverter (Enhanced

Protection) Platform

Rev. 0.2

ANALOG DEVICES Page 22

bytes and buffers that can be streamed using the GUI. The program will limit the total buffer size to

1.7k bytes. The number of variables plotted can be increased by reducing the buffer size, which is

maximum 200, although a total maximum selected variable size of 8 bytes is allowed (e.g. 2xSINGLE

or 4xINT16, or 1xSINGLE+2xINT16 etc).

The steps to prepare for plotting of variables are (refer to Figure 11):

1. Select all of the variables to be plotted and whether each one is to be on Plot 1 or Plot 2, bearing

in mind the maximum buffer memory size (1.7k) and the maximum byte count per buffer (8).

2. Down Sampling factor – the buffer time slice length equals the PWM switching period x Down

Sampling ratio, so for a down sampling ratio of 1, the sampling period will be 100s, and with a

buffer length of 200, the plot time slices will be of 20ms length. To look at longer time slices,

increase the down sampling factor.

3. Press Update Configuration

4. On the Control and Monitor tab, press Start Plotting.

5. If the variables are to be changed, press Stop Plotting and return to the Configure tab to change

the configured variables.

10 Other Board Features

This quick start guide describes operation of the inverter platform as controlled from an ADSP-CM408

EZkit. However the platform is designed to be easily operable from any appropriate processor or FPGA

board. The minimum requirement is for six PWM logic level signals (3.3V) to drive the IGBTs along

with a gate driver enable signal. Feedback signals from fault logic, manual dials/switches and sigma-

delta modulators can also be fed back to the processor or FPGA.

In addition, spare analog and digital pins are provided on the 0.1” header connectors that can be used to

route other external signals such as motor encoder feedback to the ADSP-CM408 EZkit or to another

processor or FPGA kit via the main P1 connector. Please see the schematics for more details on the

external connectors J4-J9.

Many test points are also available to allow oscilloscope viewing of board signals. These include:

 Controller-side and isolated power supply voltages

 All gate drive signals, both logic-level and isolated

 All sigma-delta modulator clock and data signals

 Analog filtered outputs of the sigma-delta bit streams that provide an analog representation of U

and V phase currents and the U-V motor line to line voltage

 Fault signals, enable signals and manual dial outputs

As mentioned previously, a digital PFC controller evaluation board can be connected to the input to

enable operation from ac mains up to 300-600W. An I2C isolator and connector is available to connect

this board to the I2C connector on one of the PFC evaluation boards, so that the PFC evaluation board

can be controlled from the control processor or FPGA.
