# Acceleration during homing (P-AXIS-00285)

P-AXIS-00285 | Acceleration during homing
Description | The parameter includes the axis acceleration during CNC-controlled homing procedure. If the parameter is unassigned, the values of the parameters P-AXIS-00005, P-AXIS-00006are adopted.
Parameter | getriebe[i].a_ref
Data type | UNS32
Data range | 0 ≤ a_ref ≤ P-AXIS-00008
Axis types | T, R
Dimension | T: mm/s² | R: °/s²
Default value | 0
Drive types | Simulation, Conventional, Terminal, Lightbus, Profidrive
Remarks | When the parameter has the value 0, it is assigned the minimum of the values of P-AXIS-00005 (a_grenz-stufe_1) and P-AXIS-00006 .
