3.
Connect the power supply to the
power stage. The controller board
power supply is taken from the
power stage. The PMSM motor is
designed for phase voltage = 25V.
Run “Device Manager” on your
system and determine which COM
port was assigned to the FTDI COM
port driver.
Virtual COM Port Setup
WARNING
:
Make sure to perform the
following steps in order. The power stage
cannot be powered without the controller
board when Brake Resistor (J2) is
populated. The absence of the controller
board leads to a high BRAKE_GATE signal,
and a large current flows through the
BRAKE_RESISTOR. This creates a
considerable burn hazard, as the resistor
will dissipate enough heat to harm on
contact. If PWM braking is used, software
must explicitly control the BRAKE_GATE
signal. Thus, the power stage board must
always be connected to the controller board.
1.
Connect the USB cable to the
MPC5744P controller board and the
host PC.
2.
Connect the controller board (
using
PCIe connector J1
) to the power
stage.

STEP-BY-STEP INSTRUCTIONS (cont.)
Start the FreeMASTER project
MPC5744P_PMSM_FOC_MCAT.pmp
located in
MTRCKTSPS5744P\sw\FreeMASTER
_control
project directory.
Kit setup (part 2/3)
In FreeMASTER\Project\Options,
choose the RS232 COM port
number that was assigned
to the virtual COM port driver and set
the communication speed to 115200
Bd.
Enable communication by pressing the
“STOP” button in FreeMASTER or by
pressing “CTRL-K.”
