# Error level for acceleration (P-AXIS-00442)

P-AXIS-00442 | Error level for acceleration for dynamic monitoring
Description | This parameter specifies the amount by which the axis velocity command value may exceed the maximum permissible axis velocity (see P-AXIS-00008) before the dynamic monitor in the interpolator generates a warning. The default value of the parameter is 1000 (100%), i.e. command velocities greater than 2.0 * P-AXIS-00008 generate a warning.

This factor limits the overall acceleration for the contouring feed rate and the LIFT motion.

Parameter | kenngr.dyn_monitoring_a_err
Data type | UNS32
Data range | 0 ≤ dyn_monitoring_a_err ≤ MAX(UNS32)
Axis types | T, R, S
Dimension | T: 0.1% | R,S: 0.1%
Default value | 1000 (100%)
Drive types | ----
Remarks | With dyn_monitoring_a_warn = 0 and dyn_monitoring_a_err = 0 the acceleration monitoring for the axis command values is deactivated!
