Safety precautions
2Safety precautions
Please note the following warnings regarding the hazards associated with development systems.
Table 1 Safety precautions
Warning: The DC link potential of this board is up to 1000 VDC. When measuring
voltage waveforms by oscilloscope, high voltage differential probes must be used.
Failure to do so may result in personal injury or death.
Warning: The evaluation or reference board contains DC bus capacitors which take
time to discharge after removal of the main supply. Before working on the drive
system, wait five minutes for capacitors to discharge to safe voltage levels. Failure to
do so may result in personal injury or death. Darkened display LEDs are not an
indication that capacitors have discharged to safe voltage levels.
Warning: The evaluation or reference board is connected to the grid input during
testing. Hence, high-voltage differential probes must be used when measuring voltage
waveforms by oscilloscope. Failure to do so may result in personal injury or death.
Darkened display LEDs are not an indication that capacitors have discharged to safe
voltage levels.
Warning: Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait five minutes after removing
power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Caution: The heat sink and device surfaces of the evaluation or reference board may
become hot during testing. Hence, necessary precautions are required while handling
the board. Failure to comply may cause injury.
Caution: Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution: The evaluation or reference board contains parts and assemblies sensitive to
electrostatic discharge (ESD). Electrostatic control precautions are required when
installing, testing, servicing or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with electrostatic
control procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component damage
or reduction in product lifetime. Wiring or application errors such as undersizing the
motor, supplying an incorrect or inadequate AC supply, or excessive ambient
temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials that
need to be removed prior to installation. Failure to remove all packing materials that
are unnecessary for system installation may result in overheating or abnormal
operating conditions.

Introduction
3Introduction
The EVAL-M3-302F evaluation board is a part of the iMOTION™ Modular Application Design Kit for drives
(iMOTION™ MADK). In order to run a motor, the mating power board is required to interface this evaluation
board.
The MADK platform is intended for use with various power stages with different control boards. These boards
can easily be interfaced through the 20-pin iMOTION™ MADK M1, or the 30-pin iMOTION™ MADK M3 interface
connector. This board is equipped with a 30-pin M3 connector and is intended for running a power factor
correction (PFC) and single motor control in parallel.
This evaluation board is designed to give comprehensible solutions of sensorless control of permanent magnet
motors over the full speed range. It provides Hall-sensor based or sensorless controls applying 3-phase and
type 3 of 2-phase modulation. PC interface is via a micro-USB connector, and the on-board debugger is
galvanically isolated. The PC interface provides a UART connection to the MCE as well as a serial wire debug
(SWD) channel to the MCU.
The EVAL-M3-302F evaluation board is available from Infineon. The features of this board are described in the
main features chapter of this document, whereas the remaining paragraphs provide information to enable the
customers to copy, modify and qualify the design for production according to their own specific requirements.
Environmental conditions were considered in the design of the EVAL-M3-302F, but the board is not qualified in
terms of safety requirements or manufacturing and operation over the entire operating temperature range or
lifetime. The boards provided by Infineon are subject to functional testing only.
Evaluation boards are not subject to the same procedures as regular products regarding returned material
analysis (RMA), process change notification (PCN) and product discontinuation (PD). Evaluation boards are
intended to be used under laboratory conditions by technical specialists only.

Figure 5 Board setup and interfaces to the MCE and the MCU
On the PC a virtual COM port is used to connect to the MCE, e.g. using the MCEDesigner. Chapter 5.1 describes
the setup and usage of the MCE and the respective tools.
Connection to the SWD debug interface of the MCU is provided via the SEGGER debug DLL. This DLL is part of
the installation of MCEDesigner but can also be installed and updated separately. The preferred C development
environment like Keil µVision is used to download and debug code on the MCU. (see Chapter 5.2)
The iMOTION™ software tools, MCEDesigner and MCEWizard, are also required to initially set up the system, as
well as to control and fine-tune the system performance to match users’ exact needs. This chapter provides
more details on setting up the system and getting started with the iMOTION™ MADK development platform.
The MCE and MCU in the IMC302A work independently from each other. Code for the MCU can be downloaded
and debugged while the MCE is running the motor.

Getting started with EVAL-M3-302F
5.1 Setting up the Motion Control Engine (MCE)
After downloading and installing the iMOTION™ PC tools (MCEWizard and MCEDesigner), the following steps
need to be executed in order to run the motor. Refer to Chapters 0 and 5.1.3 as well as MCEWizard and
MCEDesigner documentation for more information.
1. Get the latest IMC302A-F064 MCE software package available on www.infineon.com/imotion-software
website.
2. Connect PC-USB connector on the on-board debugger to the PC via USB cable.
3. Connect EVAL-M3-302F M3 30-pin interface connector (J1) to power board (for example EVAL-M3-CM615PN,
see Figure 6).
4. Use MCEWizard to enter the target motor’s system and operating parameters, as well as the hardware
parameters of the evaluation board, which will then be used to calculate controller’s digital parameter set
representing complete motor drive system. First click “Calculate” button on the “Verify & Save Page” and
then save the drive parameter set into your project directory by clicking “Export to Designer file (.txt)”.
Saved Drive System Parameter File will be later used by the MCEDesigner; refer to Chapter 0 or MCEWizard
user guide for more details.
5. Connect motor phase outputs to the motor.
6. Connect AC power to power input connector and power on system.
7. Start MCEDesigner tool and open MCEDesigner default configuration file (.irc) for IMC302A-F064 controller
(IMC302A_Vxxx.irc) by clicking “File” > “Open”. IMC302A_Vxxx.irc file is included in “IMC302A-F064 MCE
Software Package” downloaded in step 1.
8. MCEDesigner should automatically connect to the EVAL-M3-302F control board using default COM port
(indicated by green circle next to “COMx Up” status in the bottom frame of the MCEDesigner GUI). If it
cannot establish the connection, change COM port by doing following steps: (“System” window active) >
Preferences > Connection > Connect using (Chose one of the other available COM ports from the drop-down
menu).
9. In case the IMC302A-F064 IC on the EVAL-M3-302F is empty (not programmed), which will be indicated by
the pop-up window message after connecting to the MCEDesigner, then use following steps to program the
firmware and system parameters into the internal SRAM of iMOTION™ IC: Click “Tools” > “Programmer” and
select “Program Firmware and Parameters.”Browse and select the IMC302A-F064_A_Vxxx.ldf file which was
included in the “IMC302A-F064 MCE Software Package” downloaded in step 1. Then browse and select the
System Drive Parameters .txt file created in step 4. See chapter MCEDesigner setup overview 5.1.3 for more
details.
10. In case the IMC302A-F064 IC firmware has already been loaded, use the following steps to program the
system parameters into the internal SRAM of iMOTION™ IC: Click “Tools” > “Programmer”and select
“Program Parameters.” Browse and select the System Drive Parameters .txt file created in step 4. See
chapter MCEDesigner setup overview 5.1.3 for more details.
11. Start the motor by clicking the green traffic light button in the control bar.

5.1.1 iMOTION™ development tools and software
The iMOTION™Development Tool installers for MCEDesigner and MCEWizard are available for download via
Infineon iMOTIONTM website (http://www.infineon.com/imotion-software). All supported tools and software
variants are listed there. Please visit this page periodically to check for tool/software updates.
The isolated on-board debugger provides the USB to UART bridge between the PC and the target iMOTION™
device with 1kV DC galvanic isolation between the motor drive system (hot side) and the PC/debugger (cold)
side. The on-board debugger uses the SEGGER J-Link driver for UART communication with IMC302A-F064. The
J-Link driver will be installed during the MCEDesigner installation. In case the driver is not installed properly,
please go to SEGGER J-Link website to download and install the latest J-Link “Software and Documentation
pack for Windows.”

5.1.2 MCEWizard setup overview
After installing the MCEWizard, the shortcut for MCEWizard appears on the Windows desktop. Double click the
shortcut to open the MCEWizard and configure the parameters for evaluation boards or motor. Figure 7 shows
the “Welcome Page”for MCEWizard, where the MADK control board or power board can be selected via the
pull-down list. Infineon continues to release new MADK controller and power boards. Therefore, it could
happen that some of the newest power boards are not pre-configured in the MCEWizard tool and cannot be
selected in the pull-down menu. In that case, the user should select any other power board (as similar as
possible) and follow the MCEWizard setup steps by entering the parameter values that are specific to the
chosen board. Make sure both “I have modified the circuit board” and “Enable advanced question” checkmarks
are selected. Please refer to the User Guide of the corresponding power board for additional information.
After selecting the MADK control and the power board, start the MCEWizard system setup procedure by clicking
the “Next”button in the right bottom corner as shown in Figure 7.
Figure 7 Welcome Page of MCEWizard
The iMOTION™ MADK system enables users to easily test different combinations of control and power boards
with their motors. The user should be familiar with the system-level parameters related to the motor used.
There is a very limited number of parameters that are specific to the control board or power board hardware.
Table 13 provides the MCEWizard setup overview for hardware-related parameters. Similar tables will be
available in the User Guide of the specific power board. Combinations of this table and the corresponding table
of the power board provides sufficient information to set up the MADK-based motor drive system in the
shortest time.
