# Maximum permissible change speed of measured distance (P-AXIS-00417)

P-AXIS-00417 | Maximum permissible change speed of measured distance
Description | The parameter defines the maximum permissible change in speed of the measured distance within one cycle. After activation of distance control, the sensor’s actual values are monitored for change. When the maximum permissible change speed is exceeded, the error message ID 70329 is output. This detects problems with actual value detection.
