Move mark validated

this video shows how to position the servo axis using the MC move relative function block open a program pou running in a cyclic task type MC move relative add the axis variables and inputs for execute distance velocity acceleration and deceleration download changes debug mode overwrite the execute variable to true watch on for a detailed example this project consists of two servo axes screw and rotary table plus the external encoder the axis variable logical axis numbers have been defined and have been loaded after warm start and in a separate pou the servos are enabled with MC power now the goal is to program a simple test move that can be run through debug mode right here in the code close the resource dialog and turn off debug mode to start programming the positioning logic should run in the fast task so create a new program pou named positioning with LD ladder language and add an instance positioning and opened the positioning code worksheet clicking on the sheet type MC underscore move relative enter and enter again the axis input is highlighted great so again enter the axis variable is screw typing s it auto fills and enter now it's just a matter of assigning variables to the inputs of this block details on the block inputs and outputs can be found by right-clicking the block for help for motion to occur there must be an execute input as well as non zero values for velocity acceleration and deceleration double-click on the colored dot to attach a variable and execute the variable name can be start screw a local variable the data type is chosen automatically at distance the variable name can be distance screw the variable can be given an initial value say 10 millimeters and it is important here to use the IEC syntax 10.0 since the data type is l real likewise for velocity the variable name can be velocity screw with an initial velocity of 5.0 millimeters per second at acceleration a variable can also be defined but anywhere a variable is used it is also possible to define what is e calls a literal it's a constant valley that cannot change as the code runs in the name field first enter the data type which I see is L real then the pound sign and the value 40,000 point zero millimeters per second squared the underscore is an optional IEC placeholder just for legibility at deceleration any item can be copied by holding down the control key while you click and drag the copy to its place we can leave the other inputs blank and download changes there were no errors there goes the download and closed the resource window now in debug mode the values for distance and velocity have loaded to start motion open the execute variable by double-clicking on the variable name true is selected and click overwrite the motor moves and the done output becomes true to simulate...
