 2730h: 4 Buffer Position
The object contains the entry point for the available area in the reference input buffer.
Note: Do not change this value while enable interpolation (6040h bit 4) is 1.
 2730h: 6 Buffer Clear
Value (Method)
0 Disables the reference input buffer.
1 Enables the reference input buffer.
 2730h: 7 Position Data Definition
Value (Method)
0 Uses the value in the reference input buffer as an absolute value.
1 Uses the value in the reference input buffer as a relative value.
To enable changing this value, set the write pointer (2741h: 2) and the read pointer (2741h: 1)
to the same value.
 2730h: 8 Position Data Polarity
Value (Method)
0 Multiplies the value in the reference input buffer by 1.
1 Multiplies the value in the reference input buffer by -1.
This value is valid when position data definition (2730h: 7) is 1.
To enable changing this value, set the write pointer (2741h: 2) and the read pointer (2741h: 1)
to the same value.
 2730h: 9 Behavior after Reaching Buffer Position
Value (Method)
Holds the value of the read pointer (2741h: 1) when the read pointer (2741h: 1) equals the
0
write pointer (2741h: 2) and enable interpolation is 0.
Initializes the value of the read pointer (2741h: 1) when the read pointer (2741h: 1) equals
1
the write pointer (2741h: 2) and enable interpolation is 0.
This value is valid when buffer organization (2731h: 3) is 0.
Manufacturer Interpolation Data Configuration for 2nd Pro-
file (2731h) (Mode 2 Object)
