statements regarding hazards associated with development systems.
Table 1Precautions
Attention: The ground potential of the EVAL-M1-IM231-A 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-M1-IM231-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.
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-IM231-A 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

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.
To program new firmware and Drive System Parameter into IMC101T-T038, please click “Tools” menu and

types of Gatekill Input Source (as shown in Figure 16). For Gatekill Input Source configured Gatekill-Pin or Both,
iMOTION™ control IC will stop the Motor when the signal GateKill is active.
But please note that, if select comparator for Gatakill Input Source, the external Gatakill signal will be not used.
And the current sensing signal I_Shunt will be compared by the internal comparator with the “Gatekill
Comparator Reference” value set in MCEWizard only.

6.3Inverter section using CIPOS™ Micro
The inverter section is implemented using the CIPOS™ Micro IPM as sketched in Figure 18. The module includes
a combination of low VCE(sat) Trench IGBT technology and the industry benchmark rugged half-bridge drivers.
The shunt resistor section is also given, including the 0 Ω resistors R23 to R27. These resistors allow connecting
or disconnecting the shunts’ signals to connector J4. The three capacitors C24, C26 and C33 are used as
bootstrap capacitors to provide the necessary floating supply voltages VBS1, VBS2 and VBS3 respectively.
