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

11.7 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.
