It is mandatory to read the Safety Precautions section before manipulating the board. Failure to comply with the described safety precautions may result in personal injury or death, or equipment damage. www.onsemi.com EVAL BOARD USER’S MANUAL

www.onsemi.com SAFETY PRECAUTIONS It is mandatory to read the following precautions before manipulating the SECO−1KW−MCTRL−GEVB. Table 2. SECO−1KW−MCTRL−GEVB The ground potential of the 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 The ground potential of the system is NOT biased to an earth (PE) potential. When connecting the MCU board via USB to the computer, the appropriate galvanically isolated USB isolator have to be used. The recommended isolation voltage of USB isolator is 5 kV SECO−1KW−MCTRL−GEVB system contains DC bus capacitors which take time to discharge after removal of the main supply. Before working on the drive system, wait ten minutes for capacitors to discharge to safe volt- age levels. Failure to do so may result in personal injury or death. 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. The surfaces of the drive may become hot, which may cause injury. SECO−1KW−MCTRL−GEVB 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. 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. Remove and lock out power from the drive before you disconnect or reconnect wires or perform service. Wait ten 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. SECO−1KW−MCTRL−GEVB 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.

www.onsemi.com IPM Stage This stage uses NFAQ1060L36T IPM for 3−phase motor drives containing three−phase inverter, gate drivers for the inverter and a thermistor. It uses ON Semiconductor ’s Insulated Metal Substrate (IMS) Technology. Very important function is over−current protection which is deeply described in chapter – Current Measurement and Over−Current Protection. Module also contains fault pin which is keeping high level during normal state. Activation of IPM stage (connection to 15 V DC power supply) is via J1 (soldered pads). In the figure 15 is shown schematics of IPM stage also with DC link voltage measurement (voltage divider containing R46, R52, R53 and R55). Signals from 39 m/C0087 shunt resistors are going to current measurement and over−current protection circuits.
