Staging in the EfficientStages Programming Block |

Regardless of the number of stages, the PWM outputs share equal portions of the total output range. As an example, if the EfficientStages programming block is configured for 2 PWM stages, then: ▪While the input ranges from zero to 50%, the first stage modulates from zero to 100% output. ▪While the input ranges from 50% to 100%, the first stage remains at 100% output and the second stage will modulate from zero to 100% output. As a second example, if the EfficientStages programming block is configured for 3 PWM stages, then: ▪While the input ranges from zero to 33.3%, the first stage modulates from zero to 100% output . ▪While the input ranges from 33.3% to 66.6%, the first stage remains at 100% output and the second stage modulates from zero to 100% output. ▪While the input ranges from 66.6% to 100.0%, the first and the second stages remain at 100% output and the third stage modulates from zero to 100% output. Similarly if the EfficientStages programming block is configured for four stages: ▪The first stage modulates from zero to 100% while the input ranges from zero to 25%; ▪The second stage modulates from zero to 100% while the input ranges from 25% to 50%; ▪The third stage modulates from zero to 100% while the input ranges from 50% to 75%; ▪The fourth stage modulates from zero to 100% while the input ranges from 75% to 100%.
