This chapter provides general information of the Frequency Generator (FreqGen), Pulse Train Output (PTO), and Pulse Width Modulation (PWM) functions.
The functions provide simple, yet powerful solutions for your application. In particular, they are useful for controlling movement. However, the use and application of the information contained herein require expertise in the design and programming of automated control systems. Only you, the user, machine builder or integrator, can be aware of all the conditions and factors present during installation and setup, operation, and maintenance of the machine or related processes, and can therefore determine the automation and associated equipment and the related safeties and interlocks which can be effectively and properly used. When selecting automation and control equipment, and any other related equipment or software, for a particular application, you must also consider any applicable local, regional, or national standards and/or regulations.

REGULATORY INCOMPATIBILITY |
|
Ensure that all equipment applied and systems designed comply with all applicable local, regional, and national regulations and standards. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The functions provided by the expert functions libraries were conceived and designed assuming that you incorporate the necessary safety hardware into your application architecture, such as, but not limited to, appropriate limit switches and emergency stop hardware and controlling circuitry. It is implicitly assumed that functional safety measures are present in your machine design to prevent undesirable machine behavior such as over-travel or other forms of uncontrolled movement. Further, it is assumed that you have performed a functional safety analysis and risk assessment appropriate to your machine or process.

UNINTENDED EQUIPMENT OPERATION |
|
Ensure that a risk assessment is conducted and respected according to EN/ISO 12100 during the design of your machine. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
