Safety precautions
1 Safety 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-M1-05F804 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-M1-05F804 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-M1-05F804 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.

If DcBus < 36V please remove R32 and R39 while
insert R35=0ohm. Thus, please provide Vcc<20V
through and external supply. The 3.3V supply is
however generated on board fromthe provided Vcc.

6.3 Power supply
Figure 14 depicts the schematic of the power supply available on the EVAL-M1-05F310 board. The circuit
includes a LNK304 that is used to generate 15 V (VCC) directly from the DC bus. VCC is connected to the gate
drivers inside the CIPOS™Nano. The linear regulator IFX1117-ME V33 generates 3.3 V from VCC. The 3.3 V power
supply is used in the over current comparator circuit. Led LED1 is used to signal whether the board is powered
or not. Both, VCC and 3.3 V are also present on the 20 pin interface connector J2 to power circuitry on the
controller board.

6.4 Over current protection circuitry
Figure 15 displays the over current protection circuitry. The open collector output GK of the comparator is
pulled up to 3.3V and filtered through resistor R2 and capacitor C8.
The comparator threshold can be set through the voltage divider provided by resistors R1 and R7. By default for
emitter shunt trip, R7 is 660R 1 %. In single shunt application R7 needs to be changed to 3.48kΩ.
