This bit parameter is set if the DC bus level falls below the UV warning threshold set in parameter [6.50], otherwise cleared.
TheUVtriplevelis350VDC.
This parameter is set if the motor current is larger than 110% of the programmed motor rated current and the overload accumulator is greater
than 100% to warn that if the motor current is not reduced the drive will trip on I
2
t overload.
0=MotorI

t overload alarm inactive
1= MotorI
2
t overload alarm active
This parameter is set if the heatsink temperature is greater than 90°C
0 = Heatsink temperatures below alarm threshold
1 = Heatsink temperature alarm active
Indicates that one of the drive alarms is active.
0=Drivehealthy,noalarmactive
1=Alarmactive
Contains the last 6 drive trips. Parameter [10.20] is the most recent trip and [10.25] the oldest. When a new trip occurs all the parameters
move down one, the current trip is put in [10.20] and the oldest trip is lost off the bottom of the log. Possible trips for M'Ax are shown in the
table below. At time stamps are stored for each trip (see parameters [10.41]to[10.47]). UU trips are not stored unless the drive is running
when the trip occurs.
Any trip can be initiated by the actions described or by writing the relevant trip number to parameter [10.38]. If any trips shown as user trips
are initiated the trip string is trxxx,wherexxx isthetripnumber.
