How to correct the fault
9
80
Undervoltage (fault)
The DC-link voltage is lower
than the limits.
•
too low a supply volt-
age
•
AC drive internal fault
•
a defective input fuse
•
the external charge
switch is not closed
NOTE!
This fault becomes active
only if the drive is in Run
state.
If there is a temporary supply volt-
age break, reset the fault and
restart the drive.
Do a check of the supply voltage. If
the supply voltage is sufficient,
there is an internal fault.
Ask instructions from the distribu-
tor near to you.
81
Undervoltage (alarm)
10
91
Input phase
The input line phase is
missing.
Do a check of the supply voltage,
the fuses and supply cable.
11
100
Output phase super-
vision
The measurement of cur-
rent tells that there is no
current in 1 motor phase.
Do a check of the motor cable and
the motor.
13
120
AC drive undertem-
perature (fault)
Too low a temperature in
the heatsink of the power
unit or in the power board.
The heatsink temperature is
less than -10 °C.
121
AC drive undertem-
perature (alarm)
14
130
AC drive overtemper-
ature (fault, heatsink)
Too high a temperature in
the heatsink of the power
unit or in the power board.
The heatsink temperature is
more than 100 °C.
Do a check of the actual quantity
and flow of cooling air.
Examine the heatsink for dust.
Do a check of the ambient temper-
ature.
Make sure that the switching fre-
quency is not too high in relation to
the ambient temperature and the
motor load.
131
AC drive overtemper-
ature (alarm, heat-
sink)
132
AC drive overtemper-
ature (fault, board)
133
AC drive overtemper-
ature (alarm, board)
15
140
Motor stalled
The motor stalled.
Do a check of the motor and the
load.
16
150
Motor overtempera-
ture
There is too heavy a load on
the motor.
Decrease the motor load. If there is
no motor overload, do a check of
the temperature model parame-
ters.
17
160
Motor underload
There is not a sufficient load
on the motor.
Do a check of the load.
