[UnderVolt Thresh]

The AC input voltage level below which an undervoltage fault (F4 “AC
Undervoltage”) will be detected. A typical value is 85% of the nominal AC line
voltage (Par 466 [AC Line Voltage]). This fault can only occur while the drive is
running.

ATTENTION: Setting this parameter to 0 “Ignore” or 1 “Alarm”, could result in motor and/or equipment damage. If set to
“Ignore” or “Alarm”, it is strongly recommended that an external means of protecting against this condition be provided.

ATTENTION: Par 478 [Spd Loss Flt Cfg] must be set to 1 “Fault” if Par 458 [SpdReg FB Bypass] is set to 0 “Disabled”. Failure
to observe this precaution could result in high motor speeds, equipment damage, and/or bodily injury if a “Spd Fdbk Loss”
alarm condition were encountered.

ATTENTION: Setting Par 479 [MtrOvrld Flt Cfg] to 0 “Ignore” or 1 “Alarm”, could result in motor and/or equipment damage.
Ensure that the motor is properly sized for the application and that a separate device is installed that monitors for and
signals a motor overload condition.
