About this document
Scope and purpose
This User Guide provides an overview of the evaluation board EVAL-M3-302F including its main features, key
data, pin assignments and mechanical dimensions.
EVAL-M3-302F is an evaluation board as part of the iMOTION™ modular application design kit (MADK). This
board features and demonstrates Infineon’s advanced motion control engine (MCE 2.0) technology for
permanent magnet motor drives over the full speed range.
The evaluation board EVAL-M3-302F was developed to support customers during their first steps designing
applications using permanent magnet motors via sensorless sinusoidal control.
The IMC302A contains two cores –the Motion Control Engine (MCE) and an additional microcontroller (MCU).
MCE support files and documentation will be available from the Infineon website. The MCU core-related CMSIS
pack can be downloaded from the KEIL IDE and this document does not cover those topics.

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 1 shows the evaluation board EVAL-M3-302F. This documentexplains the features and details of thisboard
as well as the control IC, IMC302A-F064.

4.1 Functional description
Figure 2 shows the block diagram of the EVAL-M3-302F. The IMC302A-F064 provides a built-in, closed loop and
sensorless control algorithm using the unique flexible Motion Control Engine (MCE) for permanent magnet
motors, and additionally a boost or totem pole power factor correction (PFC). The MCE™consists of a collection
of control elements, motion peripherals, a dedicated motion control sequencer and internal memory to map
internal signal nodes. IMC302A-F064 also employs a unique single shunt current reconstruction circuit in addition
to a leg shunt current sensing circuit to eliminate additional analog/digital circuitry.
The integrated MCU is based on an Arm® Cortex® M0 core. It is internally connected to the MCE via a fast serial
port. The debug interface (SWD) is routed to the on-board debug interface via a galvanic isolation.
