1 Safety precautions
In addition to the precautions listed throughout this manual, please read and understand the following statements regarding hazards associated with development systems.
Table 1 Precautions
Attention: The ground potential of the EVAL-M1-IM231-A system is biased to a negative DC
bus voltage potential. When measuring voltage waveform by oscilloscope, the scope’s ground needs to be isolated. 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.
Attention: EVAL-M1-IM231-A system contains DC bus capacitors which take time to
discharge after removal of the main supply. Before working on the drive system, wait three 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.
Attention: Only personnel familiar with the drive and associated machinery should plan
or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.
Attention: The surfaces of the drive may become hot, which may cause injury.
Attention: EVAL-M1-IM231-A system contains parts and assemblies sensitive to
Electrostatic Discharge (ESD). Electrostatic control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with electrostatic control procedures, refer to applicable ESD protection handbooks and guidelines.
Attention: A drive, incorrectly applied or installed, can result in component damage or
reduction in product lifetime. Wiring or application errors such as under sizing the motor, supplying an incorrect or inadequate AC supply or excessive ambient temperatures may result in system malfunction.
Attention: Remove and lock out power from the drive before you disconnect or reconnect
wires or perform service. Wait three minutes after removing power to discharge the bus capacitors. Do not attempt to service the drive until the bus

Attention: EVAL-M1-IM231-A system is shipped with packing materials that need to be
removed prior to installation. Failure to remove all packing materials which are unnecessary for system installation may result in overheating or abnormal operating condition.

Introduction
2 Introduction
The EVAL-M1-IM231-A evaluation board is a part of the iMOTION Modular Application Design Kit for drives (iMOTION MADK).
The MADK-platform is intended to use various power stages with different control boards. These boards can easily be interfaced through the 20 pin iMOTION MADK-M1 interface connector.
This evaluation board is designed to give comprehensible solutions of a power stage based on the Infineon's CIPOS Micro Pro Intelligent Power Module (IPM). The board is equipped with all assembly groups for sensor less field oriented control (FOC). It provides a single-phase AC-connector, rectifier, DC-link and 3-phase output for power. It contains emitter-shunts for current sensing and a voltage divider for DC-link voltage measurement.
The EVAL-M1-IM231-A evaluation board is available from Infineon. The features of this board are described in the design feature 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-M1-IM231-A. The design was tested as described in this document but not qualified regarding safety requirements or manufacturing and operation over the whole 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 specialists only.

5 Getting Started with EVAL-M1-IM231-A
In order to run the motor system, a combination of the iMOTION MADK power board EVAL-M1-IM231-A and the matching MADK control board (with M1 connector, EVAL-M1-101T for example in this chapter) is required. The iMOTION Software Tools MCEDesigner and MCEWizard are also required in order to initially setup 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 iMOTION MADK development platform.
5.1 Setting up the system
After downloading and installing the iMOTION PC Tools (MCEWizard and MCEDesigner), following steps need to be executed in order to run the motor. Refer to chapters 5.2.1 and 5.2.2 as well as MCEWizard and MCEDesigner documentation for more information.
Figure 4 System connection example using EVAL-M1-101T and EVAL-M1-IM231-A
1. Get the latest ”IMC101T-T038 MCE Software Package” available on www.infineon.com/imotion-software web page.
2. Connect PC-USB connector on the on-board-debugger to the PC via USB cable.
3. Connect EVAL-M1-101T’s M1 20-pin interface connector (J2) to power board (For example EVAL-M1-IM231-A, see Figure 4).
4. Use MCEWizard to enter the target motor’s system and operating parameters, as well as evaluation board’s hardware parameters, 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 5.2.1 or MCEWizard User Guide for more details.
5. Connect motor phase outputs to the motor.
