Option

Install the FreeMASTER debugging

tool. Download the application at

freescale.com/freemaster.

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.

Run “Device Manager” on your

system and check which COM port

was assigned to the CP210x COM

port driver.

Connect the MC9S12ZVML128

evaluation board and the host PC

via the supplied USB cable.

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

Start the FreeMASTER project

MC9S12ZVML128_BLDC_

Sensorless.pmp located in

MTRCKTSBNZVM128\SW\

MC9S12ZVML128_BLDC_

Sensorless project directory.

Enable communication by pressing

the “STOP” button in the

FreeMASTER, or by pressing

“CTRL+K.”

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

When the power supply is

connected to EVB board, the BLDC

motor is in stop mode. The user

switch starts the motor.

The application is controlled

by user controls built into

MC9S12ZVML128 evaluation board

or by the FreeMASTER interface.

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

Analyze behavior of BLDC motor

during transients by opening

“Speed Scope.” Speed Scope

displays scope of “Actual Speed

RPM” and “Required Speed RPM”

variables.

Change the maximum allowed

value of DC bus current by

modifying “DC bus Current Limit” in

the variables watch window.
