Safety precautions

1

In addition to the precautions listed throughout this manual, please read and understand the following
statements regarding hazards associated with development systems.

Table 1

Safety precautions

Precautions

Caution: The ground potential of the EVAL-C101T-IM231 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. Darkened display LEDs are not an indication that capacitors have
discharged to safe voltage levels.

Caution: EVAL-C101T-IM231 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.

Caution: 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.

Caution: The surfaces of the drive may become hot, which may cause injury.

Caution: The EVAL-C101T-IM231 board 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.

Caution: An incorrectly applied or installed drive can result in component damage or
reduction in product lifetime. Wiring or application errors such as undersized motor,
incorrect or inadequate DC supply, or excessive ambient temperatures may result in
system malfunction.

Caution: Remove AC input cable or turn off AC power supply. 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.

Caution: The EVAL-C101T-IM231 board 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

The EVAL-C101T-IM231 evaluation board is an evaluation design platform for complete inverter-controlled
motor drive applications based on iMOTIONTM2.0 chipset. As a form factor board for motor drive it contains
Controller (IMC101T-T038) and inverter (with CIPOSTM Micro IPM). The evaluation platform can easily be
debugged through the MCEDesigner and MCEWizard during customer first designing applications with
IMC101T-T038.

This evaluation board is designed to give comprehensible solutions of sensor-less control of permanent
magnet motors over the full speed range. It provides a single-phase AC-connector, rectifier, DC-link, controller
(with sensor less field oriented control), 3-phase output to motor. It is single shunt for current sensing and a
voltage divider for DC-link voltage measurement.

The EVAL-C101T-IM231 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-C101T-IM231. 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.

Introduction

Figure 1 shows the evaluation board EVAL-C101T-IM231. This evaluation board includes an EMI filter and
IMC101T-T038 controller, Flyback power supply to provide 15V and 3.3V, and the CIPOSTM Micro IPM – IM231­L6S1B.
