Programmable acceleration overload

For technological reasons it may be necessary to exceed the specified dynamic limit values of the drive in connection with contour affecting influencing processes e.g. to ensure a constant path velocity on polynomial contours.

The following axis-specific command combined with the assigned parameter P-AXIS-00394 permits a weighting of the axis dynamic in percent % in excess of the permissible maximum acceleration P-AXIS-00008. P-AXIS-00394 represents the permissible upper limit for the acceleration weighting factor of the axis in per mill ‰. The weighting factor refers to the feed dynamic limit values of the corresponding active slope profile.

Currently the acceleration weighting function can be used in conjunction with Contouring mode 6.

<axis_name> [ DYNAMIC DIST_SOFT | ACC_FACT<expr> { \ } ]

<axis_name>

Name of the axis

DYNAMIC

Identifier for axis dynamic weighting. Must always be programmed as the first keyword.

DIST_SOFT

Identifier for the polynomial contouring mode 6

ACC_FACT<expr>

Axis-specific weighting factor in %

\

Separator ("backslash") for clear programming of the command over multiple lines.

Notice

notice

The minimum weighting value is 100%.
The maximum weighting value is limited to P-AXIS-00394.
