MC9S08AW60 Controller Board Connections

1.3 MC9S08AW60 Controller Board Connections

Figure 1-3 shows the connection between the PC, external 12 V DC power supply, and the MC9S08AW60 controller board.

When optoisolation is needed to isolate the computer from the motor driver board and the controller board, use the optoisolated parallel command converter instead of the non-isolated parallel command converter. Command converters with ISA, PCI, USB, and ETHERNET interfaces are available.

To connect the MC9S08AW60 controller board cables:1. Connect the parallel extension cable to the parallel port of the host computer. 2. Connect the other end of the parallel extension cable to the parallel command converter (see

Figure 1-3) and connect it to the BACKGROUND header on the MC9S08AW60 controller board. Pin 1 on the command converter must be aligned with pin 1 on the controller board. This provides the connection that allows the host computer to control the board.

3. Connect the 2.1 mm output power plug from the external power supply into the power jack (see Figure 1-3) on the MC9S08AW60 controller board.

4. Apply power to the external power supply. The green power-on LED will illuminate when power is correctly applied.

2.1 MC9S08AW60

The MC9S08AW60 controller board uses a Freescale Semiconductor part, MC9S08AW60, MC9S08AW48, or MC9S08AW32, designated as U1 on the board and in the schematics. This part operates at a maximum speed of 40 MHz. The following documents provide a full description of the MC9S08AW60, including functionality information:

• MC9S08AW60 Data Sheet, (MC9S08AW60/D): Provides features list and specifications including signal descriptions, electrical and timing specifications, pin descriptions, device specific peripheral information, and package descriptions. Also provides an overview description of the microcontroller unit and detailed information about the on-chip components, including the memory and I/O maps, peripheral functionality, and control/status register descriptions for each subsystem.

Refer to these documents for detailed information about chip functionality and operation. They can be found at www.freescale.com/mcu.

2.2 RS-232 Serial Communications

The MC9S08AW60 controller board provides an RS-232 interface by the use of RS-232 level converter circuitry (see Figure 2-1). The RS-232 level converter transitions the SCI UART’s +3.3 V signal levels to RS-232 compatible signal levels and connects to the host’s serial port via the DB9F connector. Table 2-1 lists the pinout of the RS232 connector. The RxD and TxD signals are also wired to the BACKGROUND and ZGB headers so you can connect the external modules with 3.3 V signal levels logic to this SCI UART. If needed, the +12 V can be connected to the RS232 connector, pin number 1, by shorting the TP+12V1 and TP+12V2 test points. Also, the associated TPGND1 and TPGND2 test points have to be shorted.

2.3 Clock Source

The MC9S08AW60 uses its internal 243 kHz reference generator and internal FLL to multiply the input frequency and achieve 40 MHz maximum operating frequency. This reference generator can be trimmed for finer accuracy via software when a precisely timed event is input to the MCU. This provides a reliable, low-cost clock source. As an MC9S08AW60 clock source, an optionally connected external crystal or resonator can also be used, attached to pins XTAL and EXTAL.

2.4 User LED

One on-board green LED D8 is provided to be controlled by your program. This diode is accessible via GPIO PTC6 port (see Figure 2-2). Setting GPIO PTC6 to a logic 1 value will turn on the LED.

Technical Summary

2.9.1 UNI-3 BRAKE and PFC Signals

Four control signals are connected to the UNI-3 interface: BRAKE, PFC PWM, PFC ENABLE outputs, and PFC zero-cross input. These signals are connected to the MC9S08AW60 controller pins GPIO PTD1, PTD2, PTD3, and PTD5 through the zero-ohm resistors (see Figure 2-6). MC9S08AW60 controller pins GPIO PTD are also connected to the port D header. MC9S08AW60 has no other timer module, therefore the PFCPWM and PFCZC signals are connected to the GPIO for general use.

Figure 2-6. Schematic Diagram of the UNI-3 BRAKE and PFC Signals Connection

2.10 Motor Control PWM Signals and LEDs

The MC9S08AW60 controller has two dedicated TIMER/PWM units. The first unit contains six TIMER/PWM channels and the second unit contains two channels. On the MC9S08AW60 controller board, the first unit with the six TIMER/PWM channels is used as the PWM output generator. The PWM outputs can operate independently or in complementary pairs. Table 2-5 shows PWM jumper configuration. When the jumpers J20, J21, and J22 are in positions 1–3, 2–4, and the jumpers JP1, JP2, and JP3 are in position 1–2, the PWM outputs operate in complementary mode with hardware dead-time insertion (see Figure 2-7). All the PWM outputs are driven by the even TIMER/PWM channels TPM1CH0, TPM1CH2, and TPM1CH4 only. Odd PWM output channels complement their associated even channels. When jumpers J20, J21, and J22 are in positions 1–3, 2–4, and jumpers JP1, JP2, and JP3 are in position 2–3, the PWM outputs operate in complementary mode, but each PWM output is connected to its associated TPM1CHx channel (PWM0 is connected to TPM1CH0, PWM1 to TPM1CH1, etc.) with hardware dead-time insertion. The complementary PWM outputs are protected against even and odd active output TPM1CHx channels at the same time. When the even TPM1CHx channel is active, the odd PWM output is inactive, regardless of the state on the odd TPM1CHx channel. This PWM mode of operation can be useful while developing the software driver to control the PWM outputs in complementary mode without external hardware. When the jumpers J20, J21, and J22 are in positions 3–5 and 4–6, the PWM outputs operate independently without hardware dead-time insertion. PWM outputs are directly connected to their associated TPM1CHx channel outputs (PWM0 to TPM1CH0, PWM1 to TPM1CH1, etc.). Dead-time insertion can be done by the MC9S08AW60 software.

Technical Summary

For calculating the inserted dead time, the following formula should be used:

PWM output group lines are connected to the UNI-3 interface connector and to a set of six PWM LEDs via inverting buffers. These PWM LEDs indicate the status of the PWM group signals (see Figure 2-8).

Motor Protection Logic

2.11.1 Over-Current and Over-Voltage Protection

The motor driver board’s DC bus voltage and DC bus current are sensed on the power stage board. The conditioned signals are transferred to the MC9S08AW60 controller board via the UNI-3 connector. DC bus voltage and DC bus current analog input signals are compared to a limit set by trimpots. If the input analog signals are greater than the limit set by the trimpot, a 0 V fault signal is generated. A fault LED monitors the fault states. The UNI-3 DC bus over-voltage and DC bus over-current fault signal is connected to the microcontroller’s IRQ input (see Figure 2-9).

Figure 2-9. FAULT Protection Circuit

The DC bus over-voltage and DC bus over-current threshold levels can be adjusted by the trim-pots R29 and R32.

2.11.2 Temperature Sensing

Analog feedback signal for temperature of power module is transferred to the MC9S08AW60 controller board via the UNI-3 connector. This signal is connected to the controller’s AD1P7 analog input.

Technical Summary

2.12 DC Bus Current Sensing

The UNI-3 DC bus current value can be directly sensed by the ADC input pin AD1P1. The MC9S08AW60 controller board contains the hardware for sensing the peak and average values of the DC bus current. Figure 2-10 shows the DCBI peak detector and DCBI average value sensing circuitry. DCBI peak current value can be sensed by the ADC input pin AD1P2, and DCBI average value can be sensed by AD1P3. These ADC input pins can also be used as universal analog input pins on the ADC header when the zero ohm resistors R43 and R46 are not present.

Back-EMF Current Sensing

2.13 Back-EMF Current Sensing

The UNI-3 connector supplies three back-EMF current signals. These back-EMF signals on the UNI-3 connector are derived from a resistor divider network contained in the motor drive unit. These resistors scale down the attached motor’s back-EMF voltages to a 0 to +3.3 V level. The back-EMF signals are connected to the controller’s AD1P4, AD1P5, and AD1P6 analog inputs (see Table 2-7).

2.14 Quadrature Encoder/Hall-Effect Interface

The MC9S08AW60 controller board has a quadrature encoder/hall-effect interface connected to the microcontroller’s input pins PTF5, PTF6, and PTF7 for the position sensing. When any position changes occur, the TPM2CH0 (PTF4) output turns over its logical value and can generate the interrupt for new position sensing. This output can be optionally connected to the controller’s TPM2CLK (PTD4) input, when the zero-ohm resistor R76 is present. This TPM2CLK input can be used for the speed calculation (see Figure 2-11).

Technical Summary

2.15 Tacho-Generator Interface

The MC9S08AW60 controller board contains a tacho-generator interface for digital/analogue sensing with the external tacho-dynamo input. Input noise filtering is supplied on the input path, then the signal passes through the voltage limiter to avoid damaging the follow on electrical circuitry. The signal can then be passed through jumper JP4 to the ADC analog input AD1P8 for analog sensing if the jumper is in position 1–2, or to the comparator with hysteresis to PTC2 input for digital sensing if the jumper is in position 2–3 (see Figure 2-12). When jumper JP4 is in position 2–3 (digital sensing), the analog input AD1P8 can be used as a universal analog input on the port D header.

Figure 2-12. Tacho-Generator Interface

The R54 trimpot serves to adjust the working point of the comparator.

2.16 Peripheral Expansion Connectors
