Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

MOTOR CONTROL INTERFACE
PICtailTM PLUS DAUGHTER BOARD
Chapter 1. Introduction
The Motor Control Interface PICtail Plus Daughter Board acts as an interface between
Microchip’s Explorer 16 Development Board and the 3-phase power modules.
This chapter introduces and provides an overview of the Motor Control Interface PICtail
Plus Daughter Board. Topics covered include:
• Overview
• Interface Card Features
• Interface Card Setup
1.1
OVERVIEW
The Motor Control Interface PICtail Plus Daughter Board is a bridge board that
connects the Explorer 16 Development Board to the 3-phase power modules, and is
used in motor control applications involving the dsPIC33F family of motor control
devices.
Figure 1-1 shows the Motor Control Interface PICtail Plus Daughter Board. It draws
power at 9V from the Explorer 16 Development Board and carries control signals from
the Explorer 16 Development board to the 3-phase power modules. In addition, it
carries feedback signals of the motor from the 3-phase power modules to the Explorer
16 Development Board. Test points are provided on the card to monitor and measure
different analog signals to and from the motor.

HARDWARE FUNCTIONALITY
The functionality of the hardware elements and circuits in the Motor Control Interface
PICtail Plus Daughter Board are described in the following sections.
2.2.1
120-pin Signal Connector (J9)
The 120-pin Signal Connector carries signals from the I/O pins of the dsPIC device to
the Motor Control Interface PICtail Plus Daughter Board. It also carries the feedback
signals from the motor through the Motor Control Interface PICtail Plus Daughter Board
to the input pins of the dsPIC device.
The 120-pin Signal Connector handles the following signals:
• 9V DC input to the Motor Control Interface PICtail Plus Daughter Board
• PWM signals from the dsPIC device to the Motor Control Interface PICtail Plus
Daughter Board
• Voltage feedback signals from the Motor Control Interface PICtail Plus Daughter
Board to the analog channels
• Current feedback signals from the Motor Control Interface PICtail Plus Daughter
Board to the analog channels
• Encoder pulse from the Motor Control Interface PICtail Plus Daughter Board to
the dsPIC Quadrature Encoder Interface (QEI) module input pins
• Hall sensor feedback from the Motor Control Interface PICtail Plus Daughter
Board to the dsPIC Input Capture module input pins
• Fault signal communication
2.2.2
37-pin D-Type Signal Connector (J2)
The 37-pin D-type Signal Connector connects the Motor Control Interface PICtail Plus
Daughter Board to the 3-phase power modules. The Signal connector (J2) handles the
following signals to or from the Motor Control Interface PICtail Plus Daughter Board:
•
•
•
•
PWM signals to the 3-phase power modules
Voltage feedback signals from the 3-phase power modules
Current feedback signals from the 3-phase power modules
Fault signal communication
2.2.3
5V Voltage Regulator (VR1)
An LM2940 5V Voltage Regulator (VR1) takes an input of 9V DC and provides a 5V
DC regulated output to drive the various interface signals.
DS51674A-page 12
© 2007 Microchip Technology Inc.
Hardware Overview
2.2.4
Octal Buffer/Line Driver (U1)
A 74AC244 Octal Buffer and Line Driver with a 3-STATE Outputs device drives the
dsPIC PWM and Output Compare outputs to the Motor Control Interface PICtail Plus
Daughter Board. This device can handle an output current of up to 24 mA, as well as
the PWM signals and Change Notification signals.
Note:
2.2.5
Pull down resistors (1 KΩ or 4.7 KΩ) are provided at all the input pins of the
line driver (U1) on the Motor Control Interface PICtail Plus Daughter Board.
This is because the LCD on the Explorer 16 Development Board is
connected in parallel with some of the PWM pins.
Quadrature Encoder Interface (QEI)
When an incremental encoder senses the speed and position of the rotor, the QEI
signals QA, QB, and QZ are taken as feedback from the encoder. These QEI signals
are routed to the Motor Control Interface PICtail Plus Daughter Board. They are also
taken as feedback to the dsPIC device through the input pins.
Note:
FIGURE 2-2:
Figure 2-2 shows that the Explorer 16 Development Board has a 10 KΩ
potentiometer (R6), which is connected to the analog channel AN5. This
channel is also used for the QEI phase B input (QB). If the motor system
involves an encoder feedback and QEI is to be used, the R12 resistor must
be unsoldered and removed. The R24 resistor must be removed if index
pulse (QZ) is used for the QEI. After removing R12, the potentiometer (R6)
cannot be used any more. Removing R24 disconnects the temperature
sensor to dsPIC.

Motor Control Interface PICtailTM Plus Daughter Board User’s Guide
2.2.6
Hall Sensor Interface
The output of the Hall Effect Sensors is taken as feedback from the Motor Control
Interface PICtail Plus Daughter Board through the Hall Interface circuit. These signals
are carried to the Input Capture pins IC1, IC2 and IC3 of the dsPIC device through the
120-pin Signal Connector (J9).
Three test points – Hall A, Hall B, and Hall C – are available on the Motor Control Interface PICtail Plus Daughter Board to monitor the three Hall Sensor output signals.
2.2.7
Low-Pass Filtering Circuit
To aid in monitoring the PWM signals, there are three low-pass filters provided on the
Motor Control Interface PICtail Plus Daughter Board. These can be used to filter the
PWM signals PM11, PM12 and PM13 going to the top switches of the inverter. The filter
outputs FPWM1, FPWM2 and FPWM3 are provided at the test points TP23, TP24 and
TP25 respectively. These test points can be used to monitor the PWM outputs.
2.2.8
Fault Reset Circuit
On occurrence of any kind of fault (i.e., overcurrent, overvoltage, etc.) in the motor
control application, the 3-phase power modules generates a fault signal output to a
dsPIC33F device and inhibits the PWM pulses to the insulated gate bi-polar transistor
(IGBT) switches.
To recover from a fault, the dsPIC33F device drives an I/O pin (FAULT_RESET) and
clears the fault condition in the 3-phase power modules.
2.2.9
Voltage Feedback
The following voltages are taken as feedback from the 3-phase power modules through
the 37-pin D-Type Signal Connector (J2) to the Motor Control Interface PICtail Plus
Daughter Board.
• Phase voltages VPH1, VPH2 and VPH3
• Rectifier output voltage |VAC|
• DC bus voltage VBUS
These voltages are available at the test points TP4, TP5, TP6, TP7 and TP8. These
test points measure and monitor the voltages.
Multiplexing logic on the Explorer 16 Development Board allows RS-232 and SPI signals to be “crossed over” to interconnect the two boards. The analog channels AN12,
AN13, and AN14, are used for feedback of Phase 1, Phase 2, and Phase 3 voltages
respectively. However, these three voltage feedback signals also control the crossover
multiplexers.
If voltage sensing is to be used, it may be necessary to remove resisters R50, R51, and
R52, as well as components U6 and U7 from the Explorer 16 Development Board.

the D-Type Signal Connector (J2) to the Motor Control Interface PICtail Plus Daughter
Board:
•

•
Phase 1, Phase 2, and Phase 3 currents
