Siemens SINUMERIK 840D sl Programming Manual

In the following cases, there is an automatic switchover to linear approach REPOSL:
● You have not specified a value for DISR.
● No defined approach direction is available (program interruption in a block without travel
information).
● With an approach direction that is perpendicular to the current working plane.
3.14.9 Influencing the motion control
3.14.9.1 Adapting maximum axis jerk (JERKLIM)
In the part program, using command JERKLIM, the maximum jerk of an axis for path motion -
set using machine data - can be reduced or increased in critical program sections.
Requirement
The acceleration mode SOFT must be active.
Effectiveness
JERKLIM acts:
● In the AUTOMATIC operating modes
● Only on path axes
Syntax
JERKLIM[<Ax>]=<Value>
