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.

Inputs

Input	Data Type	Range	Unit	Default	Description
Execute	BOOL	0, 1	N/A	No default	On the rising edge The transition of a digital signal from low to high. AKA: positive edge., request to enable Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive. the axis group.
AxesGroup	AXES_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 PLCopen Function Block ErrorIDs.

Remarks

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

• See Coordinated Motion, the top-level topic for Coordinated Motion.
• The group must be in GroupStandby to perform motion.
  • If the group is already in GroupStandby, then MC_GrpEnable does nothing.
• 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.
