# Acceleration of step 1 in rapid mode (P-AXIS-00005)

P-AXIS-00005 | Acceleration of step 1 in rapid mode (linear slope)
Description | The parameter defines the step 1 rapid traverse acceleration (G00). For positioning in rapid traverse (G00), ramps are often chosen steeper than for the linear and circular interpolation (G01, G02, G03).
Parameter | getriebe[i].lslope_profil.a_grenz_stufe_1
Data type | UNS32
Data range | 1 ≤ a_grenz_stufe_1 ≤ P-AXIS-00008
Axis types | T, R, S
Dimension | T: mm/s² | R,S: °/s²
Default value | 1000
Drive types | ----
Remarks | This limit acceleration is generally set close to the current limit to achieve fast positioning and fast deceleration values. The acceleration ramps can be changed in the NC program. The appropriate NC commands are described in [PROG//G231] in greater detail.
