Undervoltage Detection
Lvl (Uv1)
Sets the voltage at which a
Uv1 [DC Bus Undervoltage]
fault is triggered or at which
the KEB function is activated. Usually it is not necessary to change this setting.
NOTICE:
Damage to Equipment. When you set this parameter
to a value lower than the default, you must install an AC
reactor on the input side of the power supply. If you do not
install an AC reactor, it will cause damage to the drive circuitry.
