Description
Function block enable.
When EN = TRUE, execute current MC_WriteBoolParameter computation.
When EN = FALSE, the Value output is reset to 0.
Applies only to LD programs.
See also AXIS_REF data type on page 433.
See also FB_AXIS_REF data type on page
When TRUE, writes the value of the parameter at the rising edge.
Parameter ID. See additional topics in 'See also' below.
When TRUE, the specified parameter has a new value.
Values are:
• 0 (mcImmediately) - The functionality is immediately valid.
• 1 (mcQueued) - The new functionality becomes valid when:
•
all previous motion commands set one of the following output
parameters: Done, Aborted or Error
•
the axis is not in a moving state.
Note: When (MC_ExecutionMode = 0), for all parameters except Duty Cycle (1005),
this FB can be completed successfully only when the axis state is Disabled or
StandStill,
When (MC_ExecutionMode = 0), for Parameter Duty Cycle (1005), this FB can be
completed successfully except the axis is in Homing or ErrorStop state.
For (MC_ExecutionMode = 1), this function block can be successfully completed
only when the axis state is Disabled, Standstill, or the on-going motion can
complete, ending with Standstill state
Other input values are reserved currently, and are considered as invalid
parameters.
Enable out.
Applies only to LD programs.
Axis output is read-only in LD programs.
See also AXIS_REF data type on page 442.
When TRUE, the parameter was successfully written.
When TRUE, the function block is not finished.
When TRUE, an error is detected.
