Parameter "P-0-4031, Overview of device addresses" shows the overall con‐
figuration of all available real MLD-M axes and their sercos addresses.
Element no. of
P-0-4031
High word content = sercos ad‐
dress of the axis
Significance
0
1
sercos address of Axis1 (1st logical MLD axis, of the local
axis [CCD master])
1
3
sercos address of Axis2 (2nd logical MLD axis, of an axis in
the CCD slave)

Notes on application and programming
General information
The following paragraphs use examples to show how to use axis variables in
regard to PLCopen and program porting:
Example A (project using axis vari‐
ables from the "MX_Base" library)
instMX_MoveAbsolute1(Axis:= Axis3, ...);
instMX_MoveAbsolute2(Axis:= VmAxisInt, ...);
Example B (project with user-de‐
fined axis variables)
VAR
PortalX : AXIS_REF:= ( CntrlNo := LOCAL_CNTRL, AxisNo :=
AXIS_1);
PortalY : AXIS_REF:= ( CntrlNo := LOCAL_CNTRL, AxisNo :=
AXIS_4 );
AuxiliaryAxis : AXIS_REF:= ( CntrlNo := LOCAL_CNTRL, Ax-
isNo := AXIS_2 );
Tool : AXIS_REF:= ( CntrlNo := LOCAL_CNTRL, AxisNo := AX-
IS_3 );
MasterAxis : AXIS_REF:= ( CntrlNo := LOCAL_CNTRL, Axis-
No := VMA_EXT);
END_VAR
Addressing is therefore as follows:
instMX_MoveAbsolute(Axis:=AuxiliaryAxis, ...);
- or -
instMX_MoveAbsolute(Axis:= MasterAxis, ...);
MLD function blocks and parameters for commanding axes
Functions and function blocks:
●
"MX_SetControl": Controls temporary control over local axis when con‐
trolling local axis via master communication
●
"MX_SetOpMode": Directly activates a sercos operation mode
●
"MC_Power"", "MB_PresetMode": Activate axis controller enable and
possibly preselect operation mode
●
"MC_Stop", "MB_Stop": Stop the drive
●
"MX_Command"/"MB_Command": Activate a drive command
●
"MC_Home": Activates "drive-controlled homing procedure"
●
"MC_MoveVelocity": "Preset velocity" operation mode
