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-M1-36-84A 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-M1-36-84A 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-M1-36-84A 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.

6.3 Current Measurement and Over Current Circuit

The resistors RS1 to RS3 are purposed to generate a voltage proportional to the emitter current. These voltages are available at 20 pin interface connector to give feedback to the controller. In combination with resistors R70 to R72 they are used to generate common current signal V_TRIP for all three phases. V_TRIP is always on highest level of all three phase current. This signal is used to generate gate-kill signal I_TRIP.

Figure 13 is the over current circuitry shown. Capacitor C77 and resistor R81 are filtering voltage spikes and noise on V_TRIP to avoid incident turn off.

The comparator threshold can be set through the voltage divider provided by resistors R82 and R83. By default for emitter-shunt trip, R7 is 1kΩ. In single shunt application R7 needs to be changed to 3.48kΩ.

6.4 Auxiliary Power supply

Figure 14 reports the schematic of the power supply available on the EVAL-M1-36-84A board. The circuit includes LNK304 that is used to generate 15V (VCC) directly from the DC bus. VCC is connected to the gate drivers inside the CIPOS™ IPM.

The linear regulator LD1117S33 generates 3.3V from VCC. The 3.3V power supply is used in the over current comparator circuit. LED1 is used to indicate whether the board is powered or not. Both VCC and 3.3V are also provided on the 20 pin interface connector J4 to feed circuitry on the controller board.
