The following display appears when pressing the "SI--SBR tolerance" softkey:

Figure 9-8 Safe acceleration monitoring

You can scroll between the Safety Integrated drives using the "Drive +" and "Drive

--" softkeys.

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".

To calculate the SBR tolerance, the equations from Chapter 6.4 "Safe acceleration

monitoring (SBR)" are used as basis. A tolerance of 20% is added to the value

determined in this fashion.

With the "Accept" softkey, the calculated value for the safe acceleration monitoring

is accepted in machine data 36948 $MA_SAFE_STOP_VELO_TOL and parameter

p9548 SI Motion SBR accepted.
