MC_ReadActualPosition

Name :Read the actual location command

Symbol :MC_ReadActualPosition

Illustrate:

    Used to read the current position of the axis (the axis control system manages itself), active high.
    This command can only be invoked if the location information exists (using MC_Home to complete the origin regression processing, or using the MC_SetPosition to complete the position setting).
    When VALID is set to TRUE, the POS is valid for reading the axis position.
    There is no interrupt flag for this command, and multiple commands can be run at the same time.

Parameter:

The name of the parameter	data type	IN/OUT	Parameter role	Illustrate	Default value
AXISNO	UDINT	IN	Pulse shaft number	0-7	not
ENABLE	BOOL	IN	The function block is enabled	TRUE: The function block is enabled	FALSE
VALID	BOOL	OUT	Valid signs	TRUE-POS output value is valid	FALSE
BUSY	BOOL	OUT	Busy sign	TRUE-The read position is being processed	FALSE
POS	REAL	OUT	Axis position	Current axis position, in units: unit	0
ERROR	BOOL	OUT	Error flags	TRUE：There was an error with the function block call	FALSE
ERRORID	UINT	OUT	Error codes	0：Normal, Other: Error code value	0

Example:

LD:

ST:


MC_ReadActualPosition_inst1(AXISNO := 0,
 ENABLE      := TRUE,
 VALID      => ValidOut,
 BUSY       => BusyOut,
 POS        => PosOut,
 ERROR      => ErrorOut,
 ERRORID    => ErrorIdOut);

Interpretation:

   AXISNO is 0, which means that the operating pulse axis is 0;
   ENABLE is TRUE, and the shaft position reading command is initiated;
   If ValidOut is TRUE, the axis position reading value is valid for POS.
   If BusyOut is set to TRUE, the axis position reading is in progress, and BusyOut is reset after it is completed.
   If ErrorOut is TURE, it means that there is an error and the command cannot be executed.
   If ErrorIdOut is 0, the execution is normal, and if it is not 0, there is an error and cannot be executed.
