Goals and Symptoms
A customer set "Uns" in Drive menu as 380Vac. Actually, his main power is measured at 440Vac. Would ATV58's output reach to 440V while it is at full speed( motor nominal voltage is 380Vac)? Would this ATV58 have any malfunction in the future? What would be the performance ? - - -> The motor's nominal frequency is 50Hz but customer sets the "FrS" to 72Hz?
Causes and Fixes
If UNS is adjust to 380V, this value will never be exceeded but it's preferable to set FRS to 50 Hz to have the nominal voltage at the nominal frequency.
