Periodic Cams A cam can be run repeatedly when the Periodic input of the MC_CamTableSelect function block is set to TRUE . Then the cam is restarted automatically after reaching the end position. If t
Visualization Element: Online Cam Editor The online cam editor is a visualization template that displays a cam table in the visualization. With this element, you can modify the cam in online mode. The
Commanding Multiple Movements :
Overview BufferMode Some function blocks have a BufferMode input which is used to control the chronological order of movements. The buffer mode defines whether the function block works in non-buffered
Buffering/Blending from Continuous or Synchronized Movement According to PLCopen, the blending buffer mode determines the velocity at the end of the first movement. In some cases, the velocity is alre
Execution Order of Movement Function Blocks When buffered movements or blending movements are commanded, the function block instance that commands the subsequent movement must not be executed earlier
Using One Function Block Instance to Control Multiple Movements A single function block instance (for example, from MC_MoveAbsolute ) cannot be used to control multiple buffered/blending movements as
Behavior in Case of Error If an axis error occurs (for example, the axis switches to the state Errorstop ), the active movement will report an error along with all other accepted movements. If an FB e
Performance POUs which use the AXIS_REF_SM3 function block always check whether or not they are called from the bus cycle task. This check can be disabled for time-critical applications by means of th
