MC_SetOverride

 Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Writes velocity For a group of axes this means: In ACS the velocities of the different axes. In MCS and PCS it provides the velocity of the TCP and acceleration A change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate at which something speeds up or slows down. However, more generally, acceleration is a vector quantity expressing the change with time of the velocity both in magnitude and in direction. See these Wikipedia articles for more information: http://en.wikipedia.org/wiki/Velocity http://en.wikipedia.org/wiki/Euclidean_vector http://en.wikipedia.org/wiki/Rate_(mathematics) override factors.

Inputs

Input	Data Type	Range	Unit	Default	Description
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.	BOOL	0, 1	N/A	No default	Request to write the override factors.
Axis	AXIS_REF	1, 256	N/A	No default	Name of a declared instance of the AXIS_REF library function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances.. 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 The act of performing a sequence of instructions or commands. 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
