# Maximum difference after deactivation (P-AXIS-00056)

P-AXIS-00056 | Tracking mode: Maximum difference after deactivation
Description | After deactivating the tracking operation, the command position of the axis usually deviates from the command position when tracking mode is activated. Before interpolation is continued for an active NC program, this difference in position is reduced in order to be able to process the N program within any offsets. The parameter defines an upper limit for this deviation. If the deviation exceeds this limit, an error message is generated, while deviations lower than this parameter lead to a move back to the stored command position (see P-AXIS-00208).
Parameter | kenngr.diff_pos_tracking
Data type | UNS32
Data range | 0 ≤ diff_pos_tracking ≤ MAX(UNS32)
Axis types | T, R, S
Dimension | T: 0.1 µm | R,S: 0.0001°
Default value | 10000

Remarks | Setting the value to 4294967295 (in version V2.11.20xx) or to a value >= 4000000000 (from CNC version V2.11.2800 onwards) deactivates monitoring of the position difference and moving back to the saved command position.
