Chapter 1 Board Overview

1.1 MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control Drive Outline

Freescale’s MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control Drive together with a 3-Phase BLDC/PMSM Motor Control Drive board create a single unit for developing BLDC/PMSM motor-control applications.

The daughter board is connected via two connectors to the 3-Phase BLDC/PMSM Motor Control Drive board. All necessary signals are available to allow a variety of algorithms to control the 3-Phase PMSM and BLDC motors.

Figure 1-1 is an illustration of the controller daughter board.

Setup Guide

1.3 Setup Guide

Setup and connections for the MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control Drive are straightforward. The controller daughter board plugs into the main board via two 20-pin daughter board connectors. The system can be powered by a 12 to 24 V DC power supply. For safety reasons, and ease of making measurements, use a regulated DC supply. Limit power supply to under five amps.

Place jumpers to route the required signals to the controller. For jumper settings, visit chapter 2.2.4 ADC Configuration Header JP1.

A step-by-step setup procedure for the main board is available in the 3-Phase BLDC/PMSM Motor Control Drive Users Manual LVMCDBLDCPMSMUG.

WARNINGCheck the power supply voltage before plugging in the Controller Daughter Board. If an input voltage higher than 24 V is applied, the controller daughter board can be damaged.

1.4 Board Description

The Controller Daughter Board is populated with an MC9S08MP16 8-bit HCS08 controller. All the necessary signals are available on two 20-pin Rib-cage connectors, J1 and J2. BDM header J3 is used for program upload onto the controller. Headers J4 and JP1 are configuration headers and are used for board configuration. For more details, look into 2.2.3 Configuration Header J4 and 2.2.4 ADC Configuration Header JP1.

Board schematic is available in Appendix A. MC9S08MP16 Controller Daughter Board for BLDC/PMSM Motor Control Drive Schematics.



Chapter 2 Pin Description

2.1 Introduction

Inputs and outputs are located on seven connectors and headers available on the board:

• Two 20-pin daughter board connectors J1, J2

• BDM header J3

• Configuration header J4

• ADC configuration header JP1

Pin descriptions for each connector and header are identified in the following information.

Figure 2-1 shows the pin assignments for the daughter board connectors J1 and J2.

Table 2-1 and Table 2-2 show the signal descriptions. JP1 configuration header is used to share AD converter inputs for BEMF voltages and phase currents.

2.2 Signal Descriptions

Pin descriptions are identified in this subsection.

2.2.1 Daughter Board Connectors J1 and J2

Signal inputs and outputs for interconnection with the 3-Phase BLDC/PMSM LV Motor Control Drive are situated on two 20-pin connectors, located on the board’s bottom-side. Figure 2-1 shows the pin assignments. This figure shows the physical layout of the connectors, assuming that the board is oriented upside down (bottom is up). Table 2-1 and Table 2-2 contain the lists of signal descriptions for connectors J1 and J2.
