Introduction Setup Warnings
SMOS motor board includes rotating machine power transistors. Both reach temperatures enough cause burns! facilitate safe operation, 12-volt input power should come from laboratory power supply that current limited more than amps. user should aware that: Before moving scope probes, making connections, etc., generally advisable power down 12-volt supply. Standalone operation board should allowed only with insulative standoffs shown Figure 1-3. Wearing safety glasses, avoiding neckties jewelry, using shields, operation personnel trained power electronics techniques also advisable.

Setup Guide
Setup connections SMOS motor board straightforward. SMOS motor board connects Motorola embedded motion control series control board 40-pin ribbon cable. motor's power leads plug into output connectors FASTON type J8). Figure depicts completed setup with control board module. Follow these steps board read caution end:
Mount standoffs SMOS motor board locations indicated Figure 1-3. Step step optional when making connections control boards such DSP56F8xxEVM that placed flat bench next SMOS motor board. Plug 40-pin ribbon cable that supplied with Motorola embedded motion control series control boards into input connector located right-hand side motor board, considering `default front view' position Figure 1-2. other this cable links control board's 40-pin output connector. Mount control board standoffs with screws washers. This step optional with control boards. Connect 12-Vdc power supply either connector power jack JP4, labeled "Power 12V". Either one, both, used. These connectors located front left-hand corner board. 12-volt power supply should rated match motor current. Apply power SMOS motor board. green power-on lights when voltage supply present. Note that SMOS motor board powers control board, thus making only power supply necessary complete system.
CAUTION:
Since control board powered SMOS motor board, imperative that only power supply used!
Temperature, under-voltage over-voltage faults, externally sensed current overflow disables gate driver. Board reset needed. Either switch power supply turn switch position back, provide `soft reset'.
NOTE:
Check trimmer tagged Figure <2.45V (between bottom trimmer pin-2 GNDA) which thresholds current amps. closer value 1.65V, smaller bridge current that flow.

Introduction
Motorola's embedded motion control series SMOS motor board 12-volt, 8-amp, surface-mount power stage with analog SMOS driver. combination with embedded motion control series control boards, provides development platform that allows algorithms written tested without need design build power stage. supports algorithms that Hall sensors, encoder feedback, Back-EMF (electromotive force) signals sensorless control. SMOS motor board over-current protection that independent control board, some care setup required board motor protection. Current-measuring circuitry amps full scale, according trimmer position. 25oC ambient temperature operation with output current amps continuous value within board's thermal limits.

From systems point view, SMOS motor board fits into architecture that designed application development. addition hardware that needed motor, variety feedback signals that facilitate control algorithm development provided. SMOS motor board's power output stage complementary field effect transistor (MOSFET) 3-phase bridge that capable supplying sensing amps continuous current. Feedback signals include voltage, phase currents, reconstructed current, Back-EMF (electromotive force), zero crossing. following sections describe these features.
3-Phase H-Bridge
Motorola integrated 3-phase gate driver, MC33395, considerably simplifies control output stage which configured 3-phase H-bridge with complementary N-MOSFET output transistors. Together with external components this device provides

Open input pulldown important, since desirable keep power transistors case either broken connection absence power control board. order accept 5-volt MCUs 3.3-volt DSPs, Fairchild non-inverting driver DM74ALS1034M unifies level LSEx HSEx input signals. This component minimum high-state logic input voltage volts, maximum low-state logic input voltage volts. SMOS motor board will thus enable connection large number controller boards with various MCUs DSPs, example MC68HC908, HCS12, MPC555, DSP56F8XX(E), etc. Under-voltage lockout included gate drive. this feature desired, control board's under-voltage detection comparator 0.85 volts.
