Description
Axis technology object
Start of the task with a positive edge (Default value: False)
Absolute target position (Default value: 0.0)
Limit values: -1.0e ≤ Position ≤ 1.0e
12
Velocity of axis (Default value: 10.0)
This velocity is not always reached because of the configured
acceleration and deceleration and the target position to be
approached.
Limit values: Start/stop velocity ≤ Velocity ≤ maximum velocity
TRUE = Absolute target position reached
TRUE = The task is being executed.
TRUE = During execution the task was aborted by another task.
TRUE = An error has occurred during execution of the task. The
cause of the error can be found in parameters "ErrorID" and
"ErrorInfo".
Error ID for parameter "Error" (Default value: 0000)
Error info ID for parameter "ErrorID" (Default value: 0000)
Description
Use the MC_MoveAbsolute
instruction to start a positioning
motion of the axis to an absolute
position.
In order to use the
MC_MoveAbsolute instruction, the
axis must first be enabled and also
must be homed.
