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.

SEGGER J-Link website to download and install the latest J-Link “Software and Documentation pack for
Windows”.
4.2.1 MCEWizard setup overview
After installing the MCEWizard, the shortcut for MCEWizard appears on the Windows desktop. Double click the
shortcut to open the MCEWizard and configure the parameters for evaluation boards or motor. Figure 6 shows
the “Welcome Page” for MCEWizard, where the MADK control board or power board can be selected through
the pull-down list. Infineon keeps releasing new MADK controller and power boards. Therefore, it could happen
that some of the newest power boards are not pre-configured in the MCEWizard tool and cannot be selected
through the pull-down menu. In that case, the user should select any other power board (as similar as possible)
and follow the MCEWizard setup steps by entering the parameter values which are specific to the chosen board.
Make sure both “I have modified the circuit board” and “Enable advanced question” checkmarks are selected.
Please refer to the Application Note of the corresponding power board for additional information.
After selecting the MADK control and the power board, start the MCEWizard system setup procedure by clicking

Note: On-board Debugger portion of EVAL-M1-101T is galvanically isolated from the controller portion
and the attached power board. In order to program the parameters or firmware to the IMC101TT038 controller, the 3.3V DC voltage needs to be supplied to the controller portion of the EVAL-M1101T. This voltage can either be supplied by the power board (MADK power boards are designed to
supply the 3.3V to the control board through M1 or M3 connector) or by feeding the 3.3V DC voltage
to the control board through some of the available 3.3V access/test points if the power board is not
attached to the EVAL-M1-101T control board.

External NTC Temperature shutdown value can be calculated as shown below and configured in MCEWizard as
shown in Figure 18. For pull-up resistor on evaluation power board and NTC value, please refer to the power
board’s Application Note. The value of pull-up resistor on EVAL-M1-101T is 4.87 kΩ (see Figure 16).
For example, for EVAL-M1-CM610N3, the pull-up resistor on the power board is 5.6kΩ. So the total pull-up
resistance calculates to be 2.605kΩ.
The typical value of R
NTC
at 100°C is 5.388kΩ for IPM IKCM10H60GA which is used in EVAL-M1-CM610N3. If the
setting temperature is 100°C, the shutdown value should be 2.22V.

There are three input thresholds (percentage of controller supply voltage VDD) used to define the relationship
between VSP input voltage and TargetSpeed.
1. T1 (Input threshold for motor start): if the VSP analog voltage is above this threshold, motor will start
2. T2 (Input threshold for motor stop): if the VSP analog voltage is below this threshold, motor will stop
3. T3 (Input threshold for Max RPM): if the VSP analog voltage is higher or equal to this threshold, TargetSpeed
will be 16384 which is Max RPM.

Hardware description of EVAL-M1-101T
Motor speed can be calculated as shown below.
For example, PGOUT frequency is about 80 Hz and Pulse per Revolution is 6, and then the motor speed will be
800 RPM.
By default, VDD is 3.3V for EVAL-M1-101T. The input of VSP and PGOUT (pulse generation output) should be
limited within the voltage range of 0 and 3.3V. While for some application, PGOUT should be connected to
speed measurement circuit. The evaluation board EVAL-M1-101T provides FG (Frequency Generation) signal
with an open drain structure controlled by PGOUT as shown in Figure 23. And FG signal can be pull up to 30V.
The frequency of FG is the same as PGOUT, and the calculation equation for motor speed is the same.
