Do the Maple Systems HMI+PLCs (HMC) and PLCs (MLC) support Pulse Width Modulation (PWM)?
Tags: FAQ I/O Module Feature
Yes. Both our HMI+PLCs (HMC) and PLCs (MLC) support Pulse Width Modulation in MAPware-7000.

See the specific Series IO Module guide for more information specifics on which IO modules support Pulse Width Modulation (PWM) and what registers are used for configuration.

Four modes of PWM are supported for most IO modules; Normal, Clockwise/Counter-Clockwise (CW/CCW), Pulse/Direction, and Trapezoidal (Fixed Pulse). When using PWM outputs, different product lines have different maximum frequencies ranging from 1 kHz to 200 kHz.

Tech Note 7009, “Pulse Width Modulation”, describes each of the four types of PWM output, and then lists which registers to configure, how to configure those registers, and the minimum and maximum ranges of each register.

Review the IO module specification sheets to ensure PWM is available.
