Goals and Symptoms
What minimum voltage is it possible to use ATV68, when switching-off protection undervoltage? Thank you very much for your help.
Facts and Changes
Causes and Fixes
400 V range = 287 V
500 V range = 346 V
690 V range = 537 V
If the control is supplied with an external source 24V, if the voltage goes under the guarantied range, and if the fault undervoltage is deactivated (E3.08), the drive is going to supply the motor in downgraded operation (speed reduction, current limitation...) as long as no other fault appears.
