Example 2
To get a 50% Duty Cycle on PW1 and 90 % Duty Cycle on PWM2 @ 1 kHz waveform:
Set %AQ1-2 = 500 (duty cycle count)
Set %AQ3-4 = 900 (duty cycle count)
Set %AQ5-6 = 15 (prescale count)
Set %AQ7-8 = 1000 (period count)
Example 3
To turn PWM 1 output ON all the time
Set %AQ1-2 = Same value as AQ7-8 (duty cycle count)
Set %AQ5-6 = Any value (prescale count)
Set %AQ7-8 = Non-Zero value (period count)
Example 4
To turn PWM 1 output OFF all the time
Set %AQ1-2 = 0 (duty cycle count)
Set %AQ5-6 = Any value (prescale count)
Set %AQ7-8 = Any value 0 (period count)

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.
Set %AQ1 = 500 (Hz)
{Start Frequency}
Set %AQ2 = 1000 (Hz) {Run Frequency}
Set %AQ3-4 = 2000000 (Steps) {Accel Count}
Set %AQ5-6 = 2000000 (Steps) {Run Count}
Set %AQ7-8 = 1000000 (Steps) {Decel Count}
Example 3
6,000,000 steps control sequence
The following example starts at 50 Hz and ramps up to 250 Hz during the first 150,000 steps. Then,
it runs at 250 Hz for the next 5,500,000 steps. Finally during the last 350,000 steps it slows to a
stop.
Set %AQ1 = 50 (Hz)
