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.

Intended audience

This User Guide is intended for all technical specialists who have a knowledge of motor control and high-power

electronics converters. The board is intended for use under laboratory conditions.

This board will be used during design in, for evaluation and measurement of characteristics, and proof of data

sheet specifications.

Note: PCB and auxiliary circuits are NOT optimized for final customer design.

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.
