# Deceleration of step 1 (P-AXIS-00282)

P-AXIS-00282 | Deceleration of step 1 (linear slope)
Description | The parameter is used during the deceleration phase. It defines the deceleration of step 1. When initialisation takes place with value 0, the value of P-AXIS-00011 is automatically used. It is limited to the maximum acceleration P-AXIS-00008 .
Parameter | getriebe[i].lslope_profil.d_stufe_1
Data type | UNS32
Data range | 1 ≤ d_stufe_1 ≤ P-AXIS-00008
Axis types | T, R, S (version-specific)
Dimension | T: mm/s² | R,S: °/s²
Default value | 0
Drive types | ----
Remarks | The acceleration ramps can be changed in the NC program. The appropriate NC commands are described in detail in [PROG//G130, G131] in greater detail. For SAI the deceleration of step 1 is also valid for step 2 (P-AXIS-00283)! When the parameter has the value 0, it is assigned the value of P-AXIS-00011 (a_stufe_1).
