Table 27. Fault codes
Possible cause
Unbalance between power modules in
paralleled units.
Subcode in T.14:
S1 = Current unbalance
S2 = DC-Voltage unbalance
IGBT Inverter Bridge overtemperature
protection has detected too high a
short term overload current
Problem in application software
Option board or control unit changed.
Same type of board or same power
rating of drive.
Option board or drive added.
Drive of same power rating or same
type of board added.
Option board removed.
Drive removed.
Unknown option board or drive.
Subcode in T.14:
S1 = Unknown device
S2 = Power1 not same type as
Power2
IGBT Inverter Bridge overtemperature
protection has detected too high a
short term overload current
Option board or control unit changed.
Option board of different type or dif-
ferent power rating of drive.
Option board or drive added.
Option board of different type or drive
of different power rating added.
Digital input fault.
Defective option board or slot
Temperature limit values set for the
PT100 have been exceeded.
Status of KLIXON input is LOW.
The thermistor input of option board
has detected too high resistor
temperature.

Correcting measures
Should the fault re-occur, contact your
local distributor.
Contact your distributor. If you are
application programmer check the
application program.
Reset. Device is ready for use.
Old parameter settings will be used.
Reset. Device is ready for use.
Old board settings will be used.
Reset. Device no longer available.
Contact the distributor near to you.
Reset.
Set the option board parameters again
if option bard changed. Set converter
parameters again if power unit
changed.
Reset.
Set the option board parameters
again.
Remove fault situation from external
device.
Check board and slot.
Contact the nearest Vacon distributor.
Find the cause of temperature rise.
Check resistors.
Check thermistor connection (If
thermistor input of the option board is
not in use it has to be short circuited).
