PLCopen Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 416
Axes_Interlock
This function block checks MC_ReadAxisError and the actual position of both axes to verify that they are both
free of alarms and within the position tolerance specified. It is intended for use with axes that operate on the
same mechanical load and must remain within tolerance to avoid equipment damage, such as an X, X Prime
gantry system. The output “Locked? will be high to indicate that the axes are synchronized and free of errors.
Support for axes configured in rotary mode requires controller firmware 1.2.3 and PLCopen Toolbox v021.
