Zastosowanie:

PLC

SIM

Opis skrótowy:

This Function Block commands a never ending controlled motion at a specified velocity.

wejścia (8 sztuk):

nr	typ	impuls	oznaczenie	uwagi
1	B	tak	Execute	Start the action at rising edge
2	B	nie	ContinuousUpdate
3	REAL	nie	Velocity	Value of the maximum ‘Velocity’ (not necessarily reached) [u/s]
4	REAL	nie	Acceleration	Value of the ‘Acceleration’ (always positive) (increasing energy of the motor) [u/s2 ]
5	REAL	nie	Deceleration	Value of the ‘Deceleration’ (always positive) (decreasing energy of the motor) [u/s2 ]
6	REAL	nie	Jerk	Value of the ‘Jerk’ [u/s3 ]. (always positive)
7	INT	nie	Direction	Enum type (1-of-4 values: mcPositiveDirection, mcShortestWay, mcNegativeDirection, mcCurrentDirection)
8	INT	nie	BufferMode	Defines the chronological sequence of the FB. See 2.4.2 ‘Aborting versus Buffered modes’

1	B	nie	InVelocity	Commanded velocity reached
2	B	nie	Busy	The FB is not finished and new output values are to be expected
3	B	nie	Active	Indicates that the FB has control on the axis
4	B	nie	CommandAborted	‘Command’ is aborted by another command
5	B	nie	Error	‘Signals that an error has occurred within the Function Block
6	INT	nie	ErrorID	Error identification

opis działania:

Uwagi:

To stop the motion, the FB has to be interrupted by another FB issuing a new command
The signal ‘InVelocity’ has to be reset when the block is aborted by another block.
Negative velocity * negative direction = positive velocity
In combination with MC_MoveSuperimposed, the output ‘InVelocity’ is SET as long as the contribution of this FB (MC_MoveVelocity) to the set velocity is equal to the commanded velocity of this FB.
