# Weighting factor for acceleration of lowering movement (P-CHAN-00820)

P-CHAN-00820 | Weighting factor for acceleration of lowering movement
Description | This parameter weights the velocity (see P-CHAN-00803) of the lowering movement (towards the workpiece) This can be useful since the lifting movement is normally highly dynamic in order to avoid an obstacle or elevation quickly. With the weighting factor it is possible to use a reduced acceleration for the lowering movement towards the workpiece.
Parameter | dist_ctrl[i].a_weight_down (where i=0)
Data type | UNS32
Data range | 0 ≤ a_weight_down < 2000
Dimension | [0.1%]
Default value | 0
Remarks | Available as of Build V3.1.3080.12 or V3.1.3107.44 * Weighting is deactivated, i.e. lifting and lowering movements use the identical acceleration P-CHAN-00803 .
