MC_SetOverride

 Function Block - Writes velocity and acceleration override factors.

• See Function Blocks - General Rules about how inputs and outputs work.
• A change in the velocity override factor takes effect immediately on the active move.
• The velocity override factor is applied to the programmed velocity (of a MC_MoveAbsolute, MC_MoveAdditive, MC_MoveRelative, MC_MoveSuperimp, or MC_MoveVelocity function block) to determine the command velocity: 

command velocity = programmed velocity * VelFactor 

Inputs

Input	Data Type See Data Types.	Range	Unit	Default	Description
Enable	BOOL	FALSE, TRUE	N/A	No default	Request to write the override factors.
Axis	AXIS_REF	1 to 256	N/A	No default	Name of a declared instance of the AXIS_REF library function. See Axis Name and Number. See AXIS_REF Structure.
VelFactor	REAL	0.0 to 2.0	N/A	No default	Velocity override factor.

Outputs

Output	Data Type See Data Types.	Range	Unit	Description
Enabled	BOOL	FALSE, TRUE	N/A	Indicates the override values have been written.
Busy	BOOL	FALSE, TRUE	N/A	Indicates this function block is executing.
Error	BOOL	FALSE, TRUE	N/A	Indicates an invalid input was specified.
ErrorID	INT			Indicates the error if Error output is TRUE. See PLCopen Function Block ErrorIDs.
