MC_GrpEnable

 Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Changes the state of a group from GroupDisabled to GroupStandby.

If the group is already in GroupStandby, then MC_GrpEnable does nothing.

Inputs

Input	Data Type	Range	Unit	Default	Description
Execute	BOOL	0, 1	N/A	No default	On the rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge, request to enable the axis group.
AxisGroup	AXIS_GROUP_REF	N/A	N/A	No default	The axis group to be enabled.

Outputs

Output	Data Type	Range	Unit	Description
Done	BOOL	N/A	N/A	If TRUE, the command completed successfully.
Error	BOOL	N/A	N/A	If TRUE, an error has occurred.
ErrorID	INT	N/A	N/A	Indicates the error if Error output is TRUE. See the table in PLCopen Function Block ErrorID Output.

Remarks

• 
  

• The group must be in GroupStandby to perform motion.

MC_GrpEnable fails under these conditions:

• It contains no axes.
• The group is not in GroupDisabled or GroupStandby.
• One or more axes in the group are in another group that is not in GroupDisabled.
• See Group State Diagrams for more information.

See Coordinated Motion, the top-level topic for Coordinated Motion.

• 
  
• This function block starts a motion-related action and therefore stores data for calculations and error checking.
  See Call Function Blocks Multiple Times in the Same Cycle if using a dual-core controller.
