MC_SetOverride

 Function Block - Writes velocity and acceleration override factors.

Inputs

Input	Data Type	Range	Unit	Default	Description
Enable	BOOL	0, 1	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, 2.0	N/A	No default	Velocity override factor.

Outputs

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

Remarks

• 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

VelFactor := 1.25 ;   //set the velocity factor to 1.25 (125%)
Inst_MC_SetOverride( TRUE , Axis1, VelFactor ); // Inst_MC_Setoverride is an instance of MC_SetOverride
