PLCopen 1-Axis Template - ST
This 1-axis PLCopen
A vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML. template has a ST Structured text - A high-level language that is block structured and syntactically resembles Pascal. program The act of performing a sequence of instructions or commands. (called Main) that initializes, starts and runs the motion.
- Controls are included to enable Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set.
Both are required for enabling the drive./disable Removal of the ENABLE signal.
Disables power stage. the drive In electrical engineering, a drive is an electronic device to provide power to a motor or servo.
Control device for regulating the speed, torque and position of a motor.
A unit controlling a motor using the current and timing in its coils., clear faults, and display fault and axis position Position means a point in space which is described by different coordinates.
Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation.
In ACS there can be even more than six coordinates.
If the same position is described in different coordinate systems the values of the coordinates are different. information in the Control Panel.
- A subprogram reads the drive fault and position information.
- The programs are commented to ease their use.
