Safety precautions

Note: Please note the following warnings regarding the hazards associated with development systems.

Table 1 Safety precautions

Warning: The DC link potential of this board is up to 400 VDC. When measuring voltage

waveforms by oscilloscope, high voltage differential probes must be used. Failure to do so may result in personal injury or death.

Warning: The evaluation or reference board contains DC bus capacitors which take time to discharge after removal of the main supply. Before working on the drive system, wait five 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.

Warning: The evaluation or reference board is connected to the grid input during testing. Hence, high-voltage differential probes must be used when measuring voltage waveforms by oscilloscope. 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.

Warning: Remove or disconnect power from the drive before you disconnect or reconnect wires, or perform maintenance work. Wait five 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.

Caution: The heat sink and device surfaces of the evaluation or reference board may become hot during testing. Hence, necessary precautions are required while handling the board. Failure to comply may cause injury.

Caution: Only personnel familiar with the drive, power electronics and associated machinery should plan, install, commission and subsequently service the system. Failure to comply may result in personal injury and/or equipment damage.

Caution: The evaluation or reference board contains parts and assemblies sensitive to electrostatic discharge (ESD). Electrostatic control precautions are required when installing, testing, servicing or repairing the assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with electrostatic control procedures, refer to the applicable ESD protection handbooks and guidelines.

Caution: A drive that is incorrectly applied or installed can lead to component damage or reduction in product lifetime. Wiring or application errors such as undersizing the motor, supplying an incorrect or inadequate AC supply, or excessive ambient temperatures may result in system malfunction.

Caution: The evaluation or reference board is shipped with packing materials that need to be removed prior to installation. Failure to remove all packing materials that are unnecessary for system installation may result in overheating or abnormal operating conditions.

System and functional description

2.1.1 Hardware connection

Figure 4 shows the hardware connection details for the reference design board.

iMOTIONTM Link cable is needed to bridge the PC/debugger side and motor drive system (the target iMOTION™

device, hot side) with 1 kV DC galvanic isolation. Users can go to Section 5.3 for more information about iMOTION

Link.

1. Connect iMOTION

Link’s 8-pin cable to J6 with default pin order, and connect PC and iMOTION

Link with

the USB wire.

2. Then connect AC power supply (J1) and the motor (J3).

Figure 4 Hardware connection details

2.1.2 Software/firmware preparation

1. The iMOTION™ software tools MCEDesigner and MCEWizard are required to set up the system, as well as to

control and fine-tune the system performance to match users' exact needs. These tools are available for download via the Infineon website (http://www.infineon.com/imotion-software). Please check this page periodically for tool/software updates.

2. The MCE firmware then has to be downloaded on our website; select the proper version of the firmware

based on your requirements. Included in the package are the firmware (‘.ldf’), default parameters (‘.txt’), default map file (‘.map’), the file for the MCEDesigner (‘.irc’) and other documents.

3. Generate your parameters’ file.

 Use MCEWizard to enter the target motor’s system and operating parameters, as well as reference board’s

hardware parameters, which will then be used to calculate the controller’s digital parameter set representing the complete motor drive system.

REF_Fridge_D111T_MOS user guide

Refrigerator compressor driver reference design kit

System and functional description

 After system and operating parameters are set, go to the “Verify & Save Page” and click on “Calculate”

button. If no errors are reported, then save the drive parameter set in your project directory by clicking “Export to Designer file (.txt)” (Figure 7); if some errors are detected, double-click on the error message (highlighted in RED) and adjust the related parameters. Saved Drive System Parameter File will be later used for programmers.

Note: After you log-in on myInfineon, you could download the default MCEwizard file (.mc2) for this

board, you only need to modify the parameters related to your motor to make things easier and save time

4. Generate the script if available. For users who are running the board for the first time, it is recommended

not to use this function first, but to add the script function after the motor performance commissioning is completed.

2.1.3 Program firmware/parameters/script

The REF_Fridge_D111T_MOS reference design kit is shipped with pre-programmed firmware and default parameters, since the functional tests were done before the shipment. Users need to program their parameters, as the motor is different from the one under test.

The following steps have to be performed in order to make a blank IMD111T working:

 Program the firmware of the MCE  Program parameter sets for system and motor  Program customer script file (optional)

 Program the combined file, which is combined by MCEWizard containing all three items above. Customer

script file is optional depending on whether it is available. The combined file is usually used for production, since it only needs to be programmed once.

The programming process is as follows:

1. Start the MCEDesigner tool and open MCEDesigner default configuration file (‘.irc’) for IMD111T device

(IMD111T_Vxxx.irc) by clicking “File” > “Open.”

Note: The IMD111T_Vxxx.irc file is included in the downloaded firmware package “IMD111T MCE

Software Package.”

2. Power the iMOTION

control IC with 3.3 V. It is recommended to program the IC with the 3.3 V isolated power supply that comes from the iMOTIONTM Link; there is a switch on the iMOTIONTM Link to enable the 3.3 V output. The iMOTIONTM control IC will also be powered by the on-board auxiliary power supply after the AC source is powered, but caution due to high voltage.

Note: The output voltage of LDO combined in the IMD111T-6F040 is 5 V, i.e. the controller of IMD111T-

6F040 is powered by 5 V. However, it is also possible to use the 3.3 V power supply in the iMOTIONTM Link to power the IMD111T-6F040 (for programmers).

3. MCEDesigner should automatically connect to the board using default COM port (Indicated by green circle

next to “COMx Up” status in the bottom frame of the MCEDesigner GUI) when iMOTIONTM control IC is powered. If it cannot establish the connection due to an incorrect COM port, change COM port by doing the
