1.5 Setup Guide
CAUTION:
Setup and connections for the SMOS EVM motor board are
straightforward. The SMOS EVM motor board connects to a Motorola
embedded motion control series control board via a 40-pin ribbon cable.
The motor’s power leads plug into one of the output connectors J2 or J4
or FASTON type (J5 J7 J8). Figure 1-3 depicts a completed setup with
control board or module.
Follow these steps to set up the board:
1. Mount 4 standoffs to the SMOS EVM motor board at the locations
indicated in Figure 1-3. Step 1 and step 3 are optional when making
connections to DSP control boards such as the DSP56F8xxEVM that
can be placed flat on a bench next to the SMOS EVM motor board.
2. Plug one end of the 40-pin ribbon cable that is supplied with Motorola
embedded motion control series control boards into input connector J1,
located on the right-hand side of the motor board, considering its ‘default
front view’ position as in Figure 1-2. The other end of this cable links to
the control board’s 40-pin output connector.
3. Mount the control board on top of the standoffs with screws and
washers. This step is optional with DSP control boards.
4. Connect a 12-Vdc power supply either to connector J3 or power jack
JP4, labeled “Power 12V”. Either one, but not both, can be used. These
connectors are located on the front left-hand corner of the board. The
12-volt power supply should be rated to match the motor current.
5. Apply power to the SMOS EVM motor board. The green power-on LED
lights when the voltage supply is present. Note that the SMOS EVM
motor board powers the control board as well.
Since the control board is powered by the SMOS EVM motor board,
it is imperative that only one power supply is used!
NOTE:
6. Temperature, under-voltage or over-voltage faults, or externally sensed
bus current overflow disables the gate driver. Board reset is needed.
Either switch the power supply off and on or provide a ‘soft reset’. To
provide the soft reset on the 140A01 board version, toggle the SW1
switch from position 3 to 2; on the 140A02 version, press the RESET
button. Refer to chapter 3.3.4 to verify the jumper positions.
Check if the trimmer tagged in Figure 1-2 is set to <2.45V (between
bottom trimmer pin-2, R131 label, and GNDA) which thresholds the dc
bus current to 10 amps. The closer its value is set to 1.65V, the smaller
the bridge current is that can flow.
