MC_GAP_CONTROL_DIRECTION

Gap Control Direction "mcGapCtrlDirectionPositive"

CA Group

 

  • The set Gap Control Direction applies to the entire CA group.

 

Successor

 

  • The size of the Gaps is regulated in each case.
  • The successor is the only mover that controls the size of the Gaps enclosed by both adjacent movers.

 

Gap Control
Mode

 

  • Gap Control Mode "mcGapCtrlModeStandard" or Gap Control Mode "mcGapCtrlModeFast" can be used to calculate the dynamic values of a directly following mover.
  • The initialization parameter Default Gap Control Mode sets the same Gap Control Mode as the default algorithm for each successor within a CA group.

 

Individual

 

  • You can change Gap Control Mode individually for each mover using any of the motion function blocks - MC_MoveAbsoluteCA, MC_MoveRelativeCA, MC_HaltCA or MC_GearInPosCA.

 

Computing power

 

  • Gap Control Mode "mcGapCtrlModeStandard" generally requires less computing power than Gap Control Mode "mcGapCtrlModeFast".

 

Gap Control Direction "mcGapCtrlDirectionBoth"

Motion
profiles

 

  • Allows more general motion profiles, for example reverse motion.

 

CA Group

 

  • The set Gap Control Direction applies to the entire CA group.

 

Successor
and
predecessor

 

  • The size of the Gaps is regulated in each case.
  • Both adjacent movers, predecessor and successor, control the size of the Gaps they enclose.

 

Gap Control
Mode

 

  • Gap Control Mode “mcGapCtrlModeStandard” or from v3.3.19 Gap Control Mode “mcGapCtrlModeFast” can be used to calculate the dynamic values of a directly following mover.
  • The initialization parameter Default Gap Control Mode sets the same Gap Control Mode as the default algorithm for each successor within a CA group.

Correlating control behavior

Neighborhood

 

  • The size of a Gaps is regulated between two neighboring movers.
  • Two Gaps are (directly) adjacent if the mover separating them is both successor and predecessor.

 

Chain

 

  • (Directly) adjacent Gaps form a (non-trivial) chain.
  • Within a chain the control of the respective Gaps is correlated.

 

Gap Control Mode

 

  • Gap Control Mode influences the correlating control type.
  • The Gap Control Mode "mcGapCtrlModeStandard" allows deviations from the target gap value for a single Gap and for the Gaps of a chain for softer control.
