Variable Duty Factor Pulse Outputs (PWM(891) Outputs)
Overview
PWM (Pulse Width Modulation) pulse outputs can be output with a specified
duty factor. The duty factor is the ratio of the pulse's ON time and OFF time in
one pulse cycle. Use the PWM(891) instruction to generate variable duty fac-
tor pulses from a built-in output.
The duty factor can be changed while pulses are being output.
