Block to configure the current position of the axis.

Ladder Representation

MW_PlcSetPosition2_G0

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
	PositionAxis1	DINT	Desired position for axis 1
	PositionAxis2	DINT	Desired position for axis 2
VAR_OUTPUT	ENO	BOOL	Output enabling
VAR	MW_PlcSetPosition2_INST_0	MW_PlcSetPosition2	Instance of access to block structure

Operation

When the EN input changes from FALSE to TRUE (rising edge), the block configures the current position of the axes according to the value of the "positionAxis" variables.

NOTE!

The stepper motor control must be enabled for both axes. Look at the user manual and parameter manual.

Example in Ladder

MW_PlcSetPosition2_example01

In the example above, the "set" contact changes the current position of the axes (5000, 10000).

The "read" contact enables the reading of the current position of the axes, allowing you to monitor the changes made.

Example in ST

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

VAR

set : BOOL := 1;

read : BOOL := 1;

doneReading : BOOL;

setPos1 : DINT := 5000;

setPos2 : DINT := 10000;

readPos1 : DINT := 0 ;

readPos2 : DINT := 0 ;

PTSCONTACT_INST_0 : FB_PTSCONTACT;

MW_PlcSetPosition2_INST_0 : FB_MW_PlcSetPosition2;

END_VAR

PTSCONTACT_INST_0(EN:=TRUE, BIT:=set);

MW_PlcSetPosition2_INST_0(

EN:=PTSCONTACT_INST_0.Q,

PositionAxis1:=setPos1,

PositionAxis2:=setPos2);

doneReading := FB_MW_PlcGetPosition2(

EN:=read,

PositionAxis1=>readPos1,

PositionAxis2=>readPos2);
