Standard following error monitoring
The parameter "getriebe[i].slep_min" is used for plausibility test for the dynamic following error monitoring.
Since in the case of non-high dynamic systems, under certain circumstances, large following errors can arise which, in rare cases, are recognized as following error even in the case of "getriebe[i].slep_dyn = 1023" (dynamic following error monitoring being as if switched off), a helpful value must be empirically determined in this case. The dynamic following error monitoring uses a digital filter which estimates the following error based on the reference variable (command value). Usually, here, a value from some of a few "mm" or " ° " can be used.
Linear following error monitoring
The parameter "getriebe[i].slep_min" defines the maximum permissible following error on axis standstill.
Non linear following error monitoring
For this type of following error monitoring the parameter is without significance.
Velocity independent following error monitoring
The parameter defines the maximum permissible following error on axis standstill.
