Safety precautions

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-M1-101T 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 and
equipment damage

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-M1-101T 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 control board, 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 DC supply or excessive ambient
temperatures may result in system malfunction.

Attention: Remove or connect this control board from or to the power drive. Wait three
minutes after removing power from the power drive 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.

Attention: EVAL-M1-101T 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-M1-101T 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 to use 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 20-pin M1 connector and is intended for single motor control only.

This evaluation board is designed to give comprehensible solutions of sensorless control of permanent magnet
motors over the full speed range. It provides a capable of 3-phase and type 3 of 2-phase modulation, a micro­USB connector and on board debugger isolated by digital isolator, and UART interface.

The EVAL-M1-101T 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-M1-101T, but it is 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 technical specialists only.

Figure 1 shows the evaluation board EVAL-M1-101T. This document explains the features and details of this board
as well as control IC which is IMC101T-T038.

3.1 Functional description

Figure 2 shows a typical motor control application block diagram using the IMC101T-T038. The IMC101T-T038
provides a built-in closed loop sensorless control algorithm using the unique flexible Motion Control Engine (MCE)
for permanent magnet motors. The MCE™ consists of a collection of control elements, motion peripherals, a
dedicated motion control sequencer and internal memory to map internal signal nodes. IMC101T-T038 also
employs a unique single shunt current reconstruction circuit in addition to leg shunt current sensing circuit to
eliminate additional analog/digital circuitry.
