Before you get started, be sure to check out our recent introduction to discrete I/O with the PLCnext platform. Analog signals from sensors allow engineers to monitor … Read more

How Pulse Width Modulation is Used in Variable Frequency Drives

In this article, learn how variable frequency drives make use of the principle of pulse width modulation to create analog-type signals from a digital source, such as with motor drives. Pulse Width Modulation, or PWM, is a commonly used strategy for creating analog types of signals from a digital source. This is a common method … Read more
