INSTRUCTIONS

This section covers software download,

development kit setup, and application

control.

Install the FT230x virtual COM port driver.

Visit ftdichip.com/drivers/vcp.htm to

download the correct driver. Select the

virtual COM port (VCP) driver based on your

operating system and processor

architecture.

Download installation software

and documentation under

“MPC56xx/MPC57xx

Development Kits” at

3. Connect the power supply to the

power stage. The controller board

power supply is taken from the

power stage. The PMSM motor is

designedfor 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.

Kit setup (part 1/3)

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.”

Kit setup (part 3/3)

www.nxp.com

Yellow LEDs D18, D19, D20 (for motor on

J200 side) and D1, D2, D3 (for motor on J1

side) have the following functionality:

•D18 (D1) flashes if application is READY

•D19 and D20 (D2 and D3) flash if

application is in CALIB or ALIGN state

•D18, D19, and D20 (D1, D2, and D3) are

ON if application is in RUN state

•D18, D19, and D20 (D1, D2, and D3)

flash quickly if application is in FAULT

state

Application Control

(part 1/8)

If no actual faults are present in the

system, all the LED-like indicators on

the FreeMASTER control page will be

dark red. If there is a fault present,

identify the source of the fault and

remove it. The fault has been

successfully removed when the

respective LED-like indicator on the

FreeMASTER control page turns off.

Application Control

(part 2/8)

STEP-BY-STEP INSTRUCTIONS (cont.)

Press the UP + DOWN buttons

(SW2+SW1 on the MPC5774P

controller board) simultaneously to

clear the fault status register once in

the FAULT state. The application can

be restarted by positioning the

RUN/STOP switch (SW1 on the Power

Stage board) to the RUN position

(transition from STOP to RUN in case

the switch was in the RUN state when

the fault event occurred).

Application Control

(part 3/8)

If all the LED-like indicators on the

FreeMASTER control page are off,

clear pending faults by pressingthe

green circled button “FAULT CLEAR”

on the FreeMASTER control page, or

alternatively by pressing the

UP+DOWN buttons (SW2+SW3 on the

Power Stage board) simultaneously.

The RUN/STOP switch (SW1 on the

Power Stage board) must be in STOP

position.

Application Control

(part 4/8)

www.nxp.com

Start the application by pressing 1 -

“RUN” on the flip/flop (ON/OFF)

switch on the FreeMASTER control

page or by positioning the RUN/STOP

switch (SW1 on the Power Stage

board) to the RUN position (transition

from STOP to RUN in case the switch

was in the RUN state when a fault

event occurred)

Application Control

(part 5/8)

Enter the required speed by assigning

this value to the “Nreq” variable in the

variables watch window. The value is

in revolutions per minute.

Alternatively, the rotor speed can be

increased/decreased by pressing the

UP/DOWN switches on the Power

Stage Board –SW2/SW3

respectively.

Application Control

(part 6/8)

STEP-BY-STEP INSTRUCTIONS (cont.)

Stop the application by pressing 0 -

“STOP” on the flip/flop (ON/OFF)

switch on the FreeMASTER control

page, or by positioning the RUN/ STOP

switch (SW1 on the Power Stage

board) to the STOP position.

Application Control

(part 7/8)

RESET the application anytime by

pressing the SW1 on the

MPC5744P controller board.
