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
Safety precautions
Precautions
Caution: The ground potential of the EVAL-M1-IM818-A board 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-M1-IM818-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.
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-M1-IM818-A 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 or connect the 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.
Caution: The EVAL-M1-IM818-A 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.

2 Introduction
The EVAL-M1-IM818-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 iMOTION™ MADK M1 interface connector which is 20 pin connector.
This evaluation board is designed to give easy-to-use power stage based on the Infineon's CIPOS™ Maxi
Inteligent Power Module (IPM). The board is equipped with all assembly circuit for sensorless field oriented

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-IM818-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 and by trained specialists only.
The block diagram of the EVAL-M1-IM818-A is depicted in Figure 1. This evaluation board includes a DC EMI
filter and soft power up circuit, 20-pin iMOTION™ MADK-M1 interface connector, auxiliary power supply to
provide 15 V and 3.3 V, and the CIPOS™ Maxi IPM IM818-MCC.
