The Pace-Setting Performance and Features of the 56F8300 Hybrid Controllers
• 16-bit revolution counter based on index signal
• 16-bit “delta count” velocity measurement
•“1/x” velocity measurement based on signal period
• Optional interrupt on home or index signal
• Optional initialization of position on home or index signal
3.2.6 Three-Phase PWM Module
The 56F8300 PWM is unique in the industry, providing the capability to drive a broad range of motor
types, well suited for power conversion systems, exceptionally high performance, and features to
satisfy the most safety-critical application. The PWM module can be used very effectively with AC
Induction, Brush DC, Brushless DC, Switched Reluctance, Permanent Magnet, and stepper motors. It
is also optimized for performance in power conversion systems. Here are some of the features and
benefits of Motorola’s PWM module:
• Each PWM module includes 6 PWM channels and a number of fault inputs
• Complementary PWM signal pairs, independent PWM signals, or a combination
— High current sink capability on PWM pins with TTL compliance
— Programmable PWM output polarity
— Programmable PWM frequency and PWM pulse width cycle
— Programmable fault protection
— Individual software-controlled PWM output
• Features of complementary channel operation
— Programmable dead-time insertion
— Separate top and bottom pulse width correction (dead-time compensation via current
status sensing or software)
— Separate top and bottom polarity control
• Double-buffered PWM register
— Reload interrupt with programmable interrupt rate
— Integral reload rates from 1 to 16
— 15-bit PWM pulse width register
— 15-bit PWM period register
— 3-bit PWM clock prescaler
• Center-aligned or edge-aligned waveforms
— Full 0% to 100% modulation
— 33.3ns resolution at IPBus clock = 60MHz for center-aligned mode
— 16.7ns resolution at IPBus clock = 60MHz for edge-aligned mode
• Up to four programmable fault inputs for each PWM module
— Programmable interrupt capability and separate interrupt vector for each input
— Programmable fault partitioning (disables some or all PWM outputs)
— Arbitrarily assigns the fault inputs to any of the PWM pins, which allows each pair of
PWM channels to be shut down individually
— Fault input filter prevents a false fault condition
— Programmable automatic fault clearing or manual fault clearing
— Operates properly even without system clock
