Description
In-Position
I:s.2/0
This bit is set when the actual position for the axis is within the in-position
band of the end position of the currently executing move. The in-position
band must be greater than or equal to the system’s standing following error
but smaller than the magnitude of the position move. If the in-position band
is not set to a large enough value, the in-position bit is not set for the move.
If the in-position band is set to a value that is too large, the in-position bit
could turn on sooner than you want.
Move Complete
I:s.2/1
The move complete bit is set when an interpolated move is no longer being
interpolated. The IMC Classic product line called this the NOSETTLE point.
Axis Stopped
I:s.2/2
A 1 in this bit indicates the axis is at rest.
Axis Held
I:s.2/3
This bit is set when the axis is being held by the Hold Move bit.
Accelerating
I:s.2/4
This bit is set when an interpolated move is accelerating.
Decelerating
I:s.2/5
This bit is set when an interpolated move is decelerating.
Reserved
I:s.2/6 through I:s.2/7
FIN[1] State
I:s.2/8
These bits reflect the current state of the corresponding fast input (FIN [1]).
FIN[2] State
I:s.2/9
These bits reflect the current state of the corresponding fast input (FIN [2]).
FIN[3] State
I:s.2/10
These bits reflect the current state of the corresponding fast input (FIN [3]).
FOUT State
I:s.2/11
This bit reflects the current state of the fast output (FOUT).
Reserved
I:s.2/12 through I:s.2/
