# Maximum permissible change in velocity of the measured distance (P-CHAN-00804)

P-CHAN-00804 | Maximum permissible change in velocity of the measured distance
Description | The parameter defines the maximum permissible change in velocity of the measured distance. When distance control is activated, the sensor actual values are monitored with respect to their change velocity. If the maximum permissible change in velocity is exceeded, the error message ID 310018 or ID 70329 is output. This detects problems with actual value detection.
Parameter | dist_ctrl[i].max_act_value_change (where i=0)
Data type | SGN32
Data range | 0 <= max_act_value_change < MAX(SGN32)
Dimension | [1µm/s or 0.001°/s]
Default value | 5000
Remarks | Available as of Build V3.1.3080.12 or V3.1.3107.44
