4.3 Test Setup

Figure 4-2 shows the position of these blocks and the connectors on the board. Use the following steps to set up the test.

  1. Connect a serial wire debug (SWD) emulator to connector J8 to debug or program the MSPM01507. Isolate the host PC from TIDA-010250 board.
  2. Connect a motor cable to the terminals J4, J5, and J6.
  3. Apply a DC bus power, AC power supply or AC mains power to the inverter by connecting the power to J1, J2, and J3.
    • The maximum output of the DC power supply is 380VDC.
    • The maximum output of the AC power supply is 265VAC, 50/60Hz.
    • AC main power is 220VAC, 50/60Hz.
