# Maximum position lag (P-AXIS-00168)

P-AXIS-00168 | Maximum position lag
Description | The parameter defines the maximum position lag.
Parameter | getriebe[i].slep_max
Data type | SGN32
Data range | MAX(SGN32) > slep_max > 10* position lag at P-AXIS-00212
Axis types | T, R, S
Dimension | T: 0.1 µm | R,S: 0.0001°
Default value | 100000
Drive types | ----
Remarks | Standard position lag monitoring: The parameter is made use of for limiting the estimated position lag in the position controller. Especially in the case of oscillating systems an internal range overshooting of the operating data in the position controller would be quite conceivable.

Linear position lag monitoring:

The parameter defines the maximum permissible position lag. This helps to avoid a reaction of the position lag monitoring (adhesive friction), for example, when the axis starts moving from standstill.

Non-linear position lag monitoring:

For this type of position lag monitoring the parameter is without significance.

Velocity-independent position lag monitoring:

This parameter sets the position lag limit when the axis is moving.
