Block Structure

Variable Type	Name	Data Type	Description
VAR_IN_OUT	Slave	BYTE	Selection of operation slave (0 - Real axis) (1 - Virtual 1 axis)
VAR_INPUT	Execute	BOOL	Block enabling
VAR_OUTPUT	Done	BOOL	Output enabling
	Busy	BOOL	Flag indicating the block has not yet been ended
	Error	BOOL	Error in the execution flag
	ErrorID	WORD	Identifier of the occurred error
VAR	MC_GEAROUT_INST_0	MC_GEAROUT	Instance of access to block structure

Operation

When this block detects a leading edge on Execute it concludes the synchronism of MC_GearIn MC_GearInPos or blocks the programmed axis. The axis will keep the speed of the moment in which the block is executed.

When the MC_GearOut block is executed, the drive does not operate in grid position. In the execution of the block the axis status will change to ContinuousMotion.

When Execute has FALSE value, Done remains FALSE. The Done output is activated when the block finishes the execution successfully, remaining at TRUE level until Execute receives FALSE.

If there is any error in the execution, the Error output is enabled and ErrorID displays an error code according to the table below.

Code	Description
67	Drive in the "Disabled" or "Errorstop" status.
71	P202 different from 4.
73	Drive is not in the "Synchronized Motion" status.
78	MC block not executed – Internal fault.

Example in Ladder

MC_GearOut_example01

In the up transition of GEAROUT_EXECUTE, the MC_GearOut block is executed. With this, the Busy and Active signals of this block are set and synchronism concluded by other blocks of synchronism between master and slave. When the process finishes, the Done output of the block is set and remains TRUE while the Execute input is set.

Example in ST

The example below displays the instructions for applying the example above in the ST language.

VAR

GEAROUT_EXECUTE, DONE : BOOL;

MC_GEAROUT_INST_0 : FB_MC_GearOut;

END_VAR

MC_GEAROUT_INST_0.Execute := GEAROUT_EXECUTE;

MC_GEAROUT_INST_0(Slave:=0);

DONE := MC_GEAROUT_INST_0.Done;
