MC_ReadAxisInfo

Name :Read axis information commands

Symbol :MC_ReadAxisInfo

Illustrate:

    Used to read axis information, active high.
    VALID: If TRUE is output, the axis information is read.
    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：Reading axis information is valid	FALSE
BUSY	BOOL	OUT	Busy sign	TRUE：Read the axis information	FALSE
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
POWERON	BOOL	OUT	Axis enable flags	TRUE：The axis is enabled	FALSE
HOMED	BOOL	OUT	Back to origin logo	TRUE：Returned to the original (or axis position set)	FALSE
SOFTPOSLIMIT	BOOL	OUT	The software is triggering the flag at the positive limit	TRUE：The software positive limit has been triggered	FALSE
SOFTNEGLIMIT	BOOL	OUT	Software negative limit trigger flag	TRUE：The software negative limit has been triggered	FALSE

MC_ReadAxisInfo_inst1(AXISNO := 0,
 ENABLE      := TRUE,
 VALID      => ValidOut,
 BUSY       => BusyOut,
 ERROR      => ErrorOut,
 ERRORID    => ErrorIdOut,
 POWERON    => PowerOnOut,
 HOMED    => IsHomedOut);
 SOFTPOSLIMIT => SoftPosLimitOut;
 SOFTNEGLIMIT => SoftNegLimitOut;

Interpretation:

   AXISNO is 0, which means that the operating pulse axis is 0;
   ENABLE is TRUE, and the command to read the axis information is started.
   If ValidOut is set to TRUE, the axis information is valid.
   BusyOut is TRUE, which means that the axis information is read, and BusyOut is reset after completion.
   If ErrorOut is TURE, it indicates that there is an error and 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.
   If PowerOnOut is TRUE, the axis is enabled.
   IsHomedOut is TRUE, which means that the axis has been returned to its original (or the axis position has been set);
   SoftPosLimitOut is TRUE, which means that the current position of the axis has triggered the software positive limit.
   If SoftNegLimitOut is TRUE, the current position of the axis has triggered a software negative limit
