Introduction
Some automation tasks can be quickly and easily solved by integrating blocks in
the CPU. It is important within this context for the adopted solution to be supported
by a user-friendly graphic interface. This chapter gives you an overview of the
numerous solutions for technological tasks provided by software packages.
Easy Motion Control
Easy Motion Control consists of a set of function blocks (FBs) that contain
algorithms for closed-loop positioning. You can assemble your positioner my
interconnected individual blocks.
The function blocks from Easy Motion Control were developed according to the
"Technical Specification V1.0" from PLCopen.
Easy Motion Control is used to position an axis on a target with selectable
acceleration, velocity and deceleration or move it at constant velocity. The required
travel movements are started by triggering travel function blocks.
Easy Motion Control provides the following functions:
• Inching
• Reference point approach
• Absolute/relative positioning
• Electronic gears
• Reference point setting
• Velocity override
• Closed-loop controlling
• Simulation
• Preassembled drivers for encoders or analog output modules
