Block to configure the current position of the axis.

Ladder Representation

MW_PlcSetPosition1_G0

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
	AxisNumber	CONST	Selected axis
	Position	DINT	Desired position
VAR_OUTPUT	ENO	BOOL	Output enabling
VAR	MW_PlcSetPosition1_INST_0	MW_PlcSetPosition1	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 axis according to the "position" value.

NOTE!

Stepper motor control must be enabled for the selected axis. Look at the user manual and parameter manual.

Example in Ladder

MW_PlcSetPosition1_example01

In the example above, the "set" contact changes the current position of axis 1 to 5000.

The "read" contact enables reading the current position of axis 1, allowing the monitoring of the change 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;

setPos : DINT := 5000;

readPos : DINT := 0 ;

PTSCONTACT_INST_0 : FB_PTSCONTACT;

MW_PlcSetPosition1_INST_0 : FB_MW_PlcSetPosition1;

END_VAR

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

MW_PlcSetPosition1_INST_0(

EN:=PTSCONTACT_INST_0.Q,

AxisNumber:=1,

Position:=setPos);

doneReading := FB_MW_PlcGetPosition1(

EN:=read,

AxisNumber:=1,

Position=>readPos);
