SI safe acceleration monitoring (SBR)

Using the softkey "SI safe acceleration monitoring", a window is displayed with the

current settings for the axis and the associated drive.

The softkey "Calculate SBR tol." leads to the window where a decision can be

made whether the calculation of the tolerance of the safe acceleration monitoring

can be agreed ("Accept" softkey) or the operation is cancelled ("Abort" softkey).

Also here, the user can adapt the recommendation.

The settings must be saved using the softkey "Confirm SI data" (see e.g. Fig.9-8).

The equations from Chapter 6.4 "Safe acceleration monitoring (SBR)" are used as

basis to calculate the SBR tolerance. A tolerance of 20% is added to the value de-

termined in this fashion.

With "Accept" the calculated value for the safe acceleration monitoring is trans-

ferred into machine data 36948: $MA_SAFE_STOP_VELO_TOL and parameter

p9548: SI motion SBR.
