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

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

Behavior in the Case of Buffered Movements When a buffered movement is commanded after MC_MoveAbsolute or MC_MoveRelative , the buffered movement is active in the same cycle where the previous movemen

Behavior in the Case of Blending A basic property of the blending behavior of CODESYS SoftMotion is that the axis moves along the same positions during blending as during a buffered movement. The only

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

Dynamic Adaptation with MC_SetOverride The dynamics (velocity, acceleration, and jerk) of the active and future movements can be adapted by using MC_SetOverride . An adaptation of the dynamics always

Forecast The forecast function can be used to query information about the future movement of an axis. An important application of forecast is to determine the time until a position is reached (similar
