11.6 PWM Examples
Example 1
To get a 50% Duty Cycle @ 10 kHz waveform on PWM1:
Set %AQ421-422 = 16,000 (duty cycle)
Set %AQ423-424 = 10,000 (frequency
Example 2
To get a 50% Duty Cycle on PW1 and 90 % Duty Cycle on PWM2 @ 1 kHz waveform:
Set %AQ421-422 = 16,000 (duty cycle)
Set %AQ423-424 = 1,000 (frequency
Set %AQ431-432 = 28,800 (duty cycle (32000 * 0.9))
Set %AQ433-434 = 1,000 (frequency
Example 3
To turn PWM 1 output ON all the time
Set %AQ421-422 = 32,000 (duty cycle)
Set %AQ423-424 = Any Value (frequency
Example 4
To turn PWM 1 output OFF all the time
Set %AQ421-422 = 0 (duty cycle)
Set %AQ423-424 = Any Value (frequency

STP Examples
Example 1
10,000,000 steps control sequence
The following example starts at 2.5 kHz and ramps up to 5 kHz during the first 1,000,000
steps. Then, it runs at 5 kHz for the next 8,000,000 steps. Finally during the last 1,000,000
steps it slows to a stop.
Set %AQ1 = 2500 (Hz)
{Start Frequency}
Set %AQ2 = 5000 (Hz) {Run Frequency}
Set %AQ3-4 = 1000000 (Steps) {Accel Count}
Set %AQ5-6 = 8000000 (Steps) {Run Count}
Set %AQ7-8 = 1000000 (Steps) {Decel Count}
Example 2
5,000,000 steps control sequence
The following example starts at 0.5 kHz and ramps up to 1 kHz during the first 2,000,000
steps. Then, it runs at 1 kHz for the next 2,000,000 steps. Finally during the last 1,000,000
steps it slows to a stop.
