Overview

This example showcases an improved PWM generator for the NI 9505. The example allows for greater use of the <2% duty cycle range to reduce motor chatter.

RT VI:
This VI shows an example of how to implement a PWM generator for use with the NI 9505. The example uses a single-cycle Timed Loop to create a PWM frequency of 20 kHz. The duty cycle input control is used to create the appropriate pulse width. The next duty cycle value is loaded at the beginning of each new period.
