2.2.2 Test Setup

  1. Optionally, use 4 included screws to attach the board to the standoffs. Each corner of the TIEVM-MTR-HVINV has a circular hole for this purpose.

  2. If not already connected, connect the daughterboard to the top of the motherboard. The 2-row header of the motherboard (J15) should align with the 2-row connector of the daughterboard (J3).
  3. Key pin 8 of daughterboard connector J3 should be clipped if it is not already done.
  4. Observe the bottom of the XDS110ISO-EVM and locate the key pin. Connect the XDS110ISO-EVM to daughterboard connector J3, such that the key pins of each board are aligned.
  5. Verify the desired state of the daughterboard boot mode switch (S1).
  6. Connect motor wires to J10.

    1. For the Estun EMJ-04APB22, the following is an example image showing how it may be connected:

    TIEVM-MTR-HVINV

  7. Connect measurement equipment, such as multimeter, oscilloscope probes, and so forth, to probe or analyze various signals and parameters. Available test points can be viewed in the board schematic (TPx).
  8. Power on the board with isolated AC or DC power supply to the J5 ACL, ACN, and Earth connector.
    1. The maximum output of the AC power supply is 265-VAC, 50/60Hz.
    2. The maximum output of the DC power supply is 380-VDC.

The following options are also available.

  • Daughterboard connector J4 pins 4 through 7 are available as SPI signals, should the user require external SPI. When doing so, the XDS110ISO-EVM on-board DAC is not available. This connection can be used by either:
    • Connecting directly to the SPI signals on daughterboard connector J4. This connection is NOT isolated, and an external isolator must be used.
    • Connecting to isolated UART interface J14, which may not be available on certain board revisions.
  • If using this connection, depopulate daughterboard resistor R8 to ensure that the XDS110ISO-EVM on-board DAC does not interfere with the SPI peripheral-to-controller signals.
  • The default board state utilizes three-phase current sensing. Should single-phase be required, refer to Section 2.1.4.2.
