Fault name
Undervoltage (fault) The DC-link voltage is lower
than the limits.

NOTE!
This fault becomes active
only if the drive is in Run
state.
Input phase

•
The load must be a mini-
mum of 10-20% for the
supervision to work.
Output phase super- The measurement of cur-
vision rent tells that there is no
current in 1 motor phase.

Possible cause
If there is a temporary supply volt-
age break, reset the fault and
restart the drive.
Do a check of the supply voltage. If
too low a supply volt-
the supply voltage is sufficient,

there is an internal fault.

malfunction
Do a check of the brake resistor
and the cabling.
If they are in good condition, there
is a fault in the resistor or the
chopper. Ask instructions from the
distributor near to you.
The ambient temperature is too
low for the drive. Move the drive in
a warmer position.
