1
Install the FreeMASTER debugging
tool. Download the application at
freescale.com/freemaster.
2
Install the CP210x virtual COM port
driver. The CP210x virtual COM
port driver installation file is available
in the “Downloads” section at
freescale.com/automcdevkits.
3
Run “Device Manager” on your
system and check which COM port
was assigned to the CP210x COM
port driver.
4
Connect the MC9S12ZVML128
evaluation board and the host PC
via the supplied USB cable.
5
Connect the power supply to the
MC9S12ZVML128 evaluation board.
Please ensure the development kit is updated
with the latest available application software
found at freescale.com/automcdevkits before
proceeding to step 6.
Software Tools Installation
6
Start the FreeMASTER project
MC9S12ZVML128_BLDC_
Sensorless.pmp located in
MTRCKTSBNZVM128\SW\
MC9S12ZVML128_BLDC_
Sensorless project directory.
7
Enable communication by pressing
the “STOP” button in the
FreeMASTER, or by pressing
“CTRL+K.”
8
Successful communication is
signalized in the status bar. If the
communication is not established,
check the USB connection between
the PC and MC9S12ZVML128
evaluation board, communication
port and speed. The
communication port and speed can
be set in the Project\Options menu
(or pressing “CTRL+T”). The
communication speed must be set
at 9600 Bd.

Quick Start Guide
6
1
When the power supply is
connected to EVB board, the BLDC
motor is in stop mode. The user
switch starts the motor.
2
The application is controlled
by user controls built into
MC9S12ZVML128 evaluation board
or by the FreeMASTER interface.
3
Enter the required speed by
changing the value of the “Required
Speed RPM” variable in the
variables watch window or by
double clicking the speed gauge in
the “Control Page.” The “Required
Speed RPM” variable is scaled in
revolutions per minute.
Application Control
4
Analyze behavior of BLDC motor
during transients by opening
“Speed Scope.” Speed Scope
displays scope of “Actual Speed
RPM” and “Required Speed RPM”
variables.
5
Change the maximum allowed
value of DC bus current by
modifying “DC bus Current Limit” in
the variables watch window.
