MDI_MoveVelocity (FB)

FUNCTION_BLOCK MDI_MoveVelocity

This function block is used to issue a velocity reference to the axis. In this mode of operation, the position loop is not used on the drive (no following error is recorded or acted upon). After Execute is issued the axis will remain in velocity control mode until motion of another control mode type is issued.

InOut:

Scope	Name	Type	Initial	Comment
Input	Execute	BOOL	FALSE	Starts the function block on a rising edge.
	Velocity	REAL	100	Value for the velocity the axis will reach in user units, for e5x0 unit is units/sec, for ACSx80 unit is RPM. Can be modified whilst Execute is true to change the axis velocity.
	Acceleration	REAL	1000	Acceleration rate(user units/sec^2 for e5x0, sec for ACSx80), range>0.
	Deceleration	REAL	1000	Deceleration rate(user units/sec^2 for e5x0, sec for ACSx80), range>0.
Inout	Axis	MDI_AxisRef		Reference to the axis structure.
Output	InVelocity	BOOL		Commanded velocity is reached.
	Busy	BOOL		Sets to true while the function block is in progress.
	CommandAborted	BOOL		Command is aborted by another command from other MDI function block.
	Error	BOOL		Signals that an error has occurred within function block.
	ErrorID	ERROR_ID		Contains the error code when there is an error.
