Safety precautions
1Safety 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-M3-TS6-665PN 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-M3-TS6-665PN 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-M3-TS6-655PN 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
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Attention: EVAL-M3-TS6-665PN 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.

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 User Manual 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
the “Next” button in the right bottom corner as shown in Figure 4.
Figure 4 Welcome Page of MCEWizard
iMOTION™ MADK system enables users to easily test different combination of control and power board with
their motors. User should be familiar with the system level parameters which are related to the motor used.
There are very limited numbers of parameters which are specific to the control board or power board
hardware. Table 6 provides the MCEWizard setup overview for hardware related parameters. Similar tables will
be available in each power board’s User Manual. Combination of this table and the corresponding table of the
power board provides enough information to setup the MADK-based motor drive system in shortest time.

5.1.1 AC Voltage sensing and MCEWizard configuration
AC voltage sensing is in the front of rectifier bridge U1 by default as shown in Figure 10. To dive the boost PFC
circuitry for EVAL-M3-TS6-665PN, the default matching MADK control board is EVAL-M3-102T.Figure 10 shows
the VAC sensing schematic of EVAL-M3-102T evaluation board.
Figure 10 The AC Voltage sensing schematic of EVAL-M3-102T
There are two AC voltage sensing modes in MCEWizard, differential mode and single-ended as shown inFigure
11.Please select differential mode for the combination between EVAL-M3-TS6-665PN and EVAL-M3-102T.
Figure 11 Vac Sensing Method configuration for EVAL-M3-102T and EVAL-M3-TS6-665PN
The high side resistors R30 and R38 or R21 and R42 for the AC voltage sensing resistor divider on the power
board EVAL-M3-TS6-665PN is 2000kΩ,and should be configured in MCEWizard as shown in Figure 12. For the
low side resistor value, please refer to the User Manual of the corresponding control board.

5.1.2 Hardware Modification for AC Voltage sensing to work with IRMCF188
As mentioned in the previous setion, AC voltage sensing is in the front of rectifier bridge BG1 by default for this
power board EVAL-M3-TS6-665PN as shown in Figure 9. But for control board EVAL-M3-188 with controller IC
IRMCF188, AC Voltage sensing should be behind the rectifier bridge BG1. To work with control board EVAL-M3-
188 or IRMCF188, power board EVAL-M3-TS6-665PN should be modified by assembling 500kΩAC Voltage
sensing resistors R31 and R29 and removing the resistors R21 and R30.
5.1.3 PFC External Current feedback configuration and calculation
The PFC shunt resistor RS4 is 100mΩf o r EVAL-M3-TS6-665PN. But for control board EVAL-M3-102T, the current
input value is product of the shunt resistance in milliohms and gain of External current sense amplifier as
shown in Figure 13.
Figure 13 PFC Current shunt feedback and sample timing
Figure 14 depicts IPFC- current feedback sensing circuity on EVAL-M3-102T evaluation board. Please note that
the default external amplification gain is less than 1 for current sense in this evaluation board.

Based on this calculation, the current input for the MADK combination of EVAL-M3-102T and EVAL-M3-TS6-
665PN is 92.3 mV/A. Please use same procedure to calculate the current input for other combinations of MADK
boards and enter it into MCEWizard.
5.1.4 PFC Overcurrent protection circuit and PFC Gatekill configuration
PFC protection circuit for EVAL-M3-TS6-665PN as shown in Figure 15, but the left side of RS4 is negative. If the
bus current Ibus is larger than the setting value, the output PFCGK of U2 will be trigger low and be active.
