Description
It indicates that the inverter received the command
from the DP Profibus network master to go into
Clear mode.
It indicates interruption in the communication
between the DP Profibus network master and the
inverter.
It indicates error in the access to the data of the
DP Profibus communication module.
Overspeed Fault.
Enabled when the real speed exceeds the value of
P0134 x (100 % + P0132) for more than 20 ms.
Fault on the Flash Memory Module (MMF-01).
High internal air temperature alarm.
Measured temperature above 75 ºC (167 °F).
Note:
- It can be disabled by setting P0353 = 1 or
Internal air overtemperature fault.
Measured temperature above 80 ºC (176 °F).
Only one sensor indicates temperature below
-30 °C.
Undertemperature fault measured on the IGBT
temperature sensors (-22 °F).
Fault on the Safety Stop relays.
Refer to the programming manual of the PLC11-01 module available on www.weg.net.
It indicates that AI1 current reference (4-20 mA or
20-4 mA) is out of the range from 4 to 20 mA.
It indicates that AI2 current reference (4-20 mA or
20-4 mA) is out of the range from 4 to 20 mA.
It indicates that AI3 current reference (4-20 mA or
20-4 mA) is out of the range from 4 to 20 mA.
It indicates that AI4 current reference (4-20 mA or
20-4 mA) is out of the range from 4 to 20 mA.
Alarm of clock with wrong time.
Fault in the output pulse feedback.
Overtemperature related to IGBT overload protection.
Temperature fault in sensor 1.
Temperature fault in sensor 2.
Temperature fault in sensor 3.
Temperature fault in sensor 4.
Temperature fault in sensor 5.
Possible Causes
Check the network master status, ensuring it is
„
in the run mode.
For further information, refer to the Profibus DP
„
communication manual.
Check if the network master is correctly
„
configured and operating properly.
Check the network installation in general -
„
cabling, grounding.
For further information, refer to the Profibus DP
„
communication manual.
Check if the DP profibus module is correctly
„
fitted in slot 3.
For further information, refer to the Profibus DP
„
communication manual.
Incorrect setting of P0161 and/or P0162.
„
Flash memory module defective.
„
Flash memory module not well fitted.
„
High ambient temperature around the inverter
„
(> 45 °C (113 °F)).

„
(113 °F)).
Ambient temperature around the inverter ≤
„
-30 °C (-22 °F).
Ambient temperature around the inverter ≤
„
-30 °C (-22 °F).
One of the relays is defective or without the
„
+24 Vdc voltage on the coil.
Cable of AI1 broken.
„
Poor contact on the signal connection on the
„
terminals.
