maxon controllers: I2t Limitation & Motor winding protection
Topic: How is a motor winding overload protection be ensured by the use of maxon controllers? Is there an adjustable time period for an "overcurrent" as possible by some frequency inverters in case...
Motor's "Nominal voltage" versus a Controller's "Supply voltage"?
Topic: Can a motor be operated with a higher controller's supply voltage than specified by the motor's "Nominal voltage"? Is there some risk that the motor winding gets damaged if a higher voltage...
EPOS4 / IDX: Manual control parameter tuning hints
Topic: Autotuning leads to stable control parameters in most cases, but for some specific application requirements it may sometimes be desired to further optimize these results. Are there any "be...
