13
UVW reversed
• The u, v, w commutation signals of the
encoder are reversed
• Check the encoder and motor wiring
14
TUNE U Encod
• Some encoder signals are present, but
commutation channel U is missing
• Check the encoder connection
15
TUNE V Encod
• Some encoder signals are present, but
commutation channel V is missing
16
TUNE W Encod
• Some encoder signals are present,
but commutation channel W is missing
18
Autotun.fail
• Drive trips during the
autotune phase
• A stop has been requested
• The SDI2 contact has been opened during the
autotuning phase
19
Brak. resist.
• Braking resistor overload
I x t:
10.39
= 100%
• Read the accumulator value in
10.39
• Check that
10.30
and
10.31
= 0, if there is no
braking resistor If there is one, check that
the configuring and the braking resistor capacities
match
• Increase the value of the resistor
• Check the resistor wiring
• Check the built-in transistor
21
Th IGBT U
• IGBT (U) overheating, ventilation
problem, ambient temperature too
high
• Load too great
• Check the ambient temperature
• Check the drive load level
• Check the frequency and temperature derating of the
drive (see Installation manual)
• Check that all the fans are working
• Check the state of the door filters
24
Motor PTC
• Triggering of motor thermal sensor
on ADI3 or MD-Encoder
• Check the motor load
• Reduce the overload level
• Check the motor ventilation and the ambient
temperature
• Check the wiring of terminal ADI3 on the control
terminal block
• Check terminals T1 and T2 of the MD-Encoder option
• See
10.37
26
24V over ld
• Overload on the +24 V power supply or
digital outputs
• Check the 24 V power supply
• Check the digital outputs
• Check the total current consumption
• See
10.37
27
ADI1 loss
• Loss of the current reference on
analog input AI1
• Check that the reference is > 3 mA
• See
10.37
28
ADI2 loss
• Loss of the current reference on
analog input ADI2
30
COM loss
• Loss of serial link communication
• Check the connectors between the configuration interface
and the drive
• Check that the cable is not damaged
• See
10.37
31
EEPROM fail.
• EEPROM problem or problem
with transfer by XPressKey (key and
drive versions different)
• Return to factory settings
(see
00.45
)
• See
10.37
• Switch off and then on again.
Transfer via the XPressKey has still taken place.
33
Stator res.
• Trip during measurement of
the stator resistance
• Adapt the drive power to that of the motor
• Check the connection of the motor cables
34
Fieldbus loss
• Disconnection of the fieldbus during
operation or error
• See
10.37
• Check the connection of the fieldbus option with the
drive
35
Sec. disable
• Problem on the secure disable input
• Give a stop command before enabling the drive
No.
