SI-SBR tolerance
The following display appears when pressing the "SI-SBR tolerance" softkey:
Figure 10-8
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 Monitor 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 "Safe Acceleration Monitor
(Page 134)" 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 Monitor is accepted
in machine data 36948 $MA_SAFE_STOP_VELO_TOL and parameter p9548 SI Motion SBR
accepted.
