The cluelesscommissioningengineer
Use-Cases
Changing load
A
B
What needsto be done?
Autoparameterization in 3RW55
Set rated motor current IeSet points:
• Type of load / application
Autoparameterization: Soft and smooth motor start guaranteed –perfect for constant and slightly changing load characteristics
How does itwork?
Ramp-up time as control value
Continuous optimization of parameters with everysingle start (initially with default-parameter set)
What needsto be kept inmind?
Underdimensioning (Soft Starter and/or motor)and/or too high switching frequency causestripping of motor overload or device self proteciton
Previously: Commissioningdifficult and time consuming
