Fault / Alarm Description Possible Causes
A046
Motor Overload
Motor overload alarm.
„
Settings of P156 is too low for the used motor.
„
Overload on the motor shaft.
A050
Power Module
Overtemperature
Overtemperature alarm from the power
module temperature sensor (NTC).
„
High temperature at IGBTs. P030> Level A050, according to
Table 14.1 on page 14-3 .
„
High ambient temperature around the inverter (> 50 °C (>
122 °F)) and high output current. For further information, refer
to of the user’s manual available for download on the website:
www.weg.net.
„
Blocked or defective fan.
„
Heatsink is too dirty, preventing the air flow.
A090
External Alarm
External alarm via DIx (option “no
external alarm” in P263 to P270).
„
Wiring on DI1 to DI8 inputs are open or have poor contact.
A128
Telegram Reception
Timeout
Alarm that indicates serial
communication fault. It indicates the
equipment stopped receiving valid serial
telegrams for a period longer than the
setting in P314.
„
Check network installation, broken cable or fault/poor contact
on the connections with the network, grounding.
„
Ensure the master always sends telegrams to the equipment in
a time shorter than the setting in P314.
„
Disable this function in P314.
A133
No Power Supply on
the CAN Interface
It indicates that the CAN interface has no
power supply between pins 25 and 29 of
the connector.
„
Measure if there is voltage within the allowed range between
pins 25 and 29 of the CAN interface connector.
„
Check if the power supply cables are not misconnected or
inverted.
„
Check for contact problems on the cable or connector of the
CAN interface.
A134
Bus Off
Buss off error detected on the CAN
interface.
„
Check for short circuit on the CAN circuit transmission cable.
„
Check if the cables are not misconnected or inverted.
„
Check if all the network devices use the same baud rate.
„
Check if the termination resistors with the right specification
were installed only at the end of the main bus.
„
Check if the CAN network was properly installed.
A135
Node Guarding/
Heartbeat
CANopen communication error control
detected communication error using the
guarding mechanism.
„
Check the times set on the master and on the slave for message
exchange. In order to prevent problems due to transmission
delays and time counting, it is recommended that the values
set for error detection by the slave be multiples of the times set
for message exchange on the master.
„
Check if the master is sending the guarding telegrams in the
time set.
„
Check problems in the communication that may cause missing
telegrams or transmission delays.
A136
Idle Master
Alarm indicates that the DeviceNet
network master is in Idle mode.
„
Set the switch that controls the master operation of the master
for Run or the corresponding bit on the configuration word of
the master software. If further information is needed, refer to the
documentation of the master used.
A137
DeviceNet Connection
Timeout
Alarm that indicates that one or more
DeviceNet connections timed out.
„
Check the network master status.
„
Check network installation, broken cable or fault/poor contact
on the connections with the network.
A138
Profibus DP Interface in
Clear Mode
It indicates that the inverter received the
command from the Profibus DP network
master to go into clear mode.
„
Check the network master status, ensuring it is in the run mode.
A139
Offline Profibus DP
Interface
It indicates interruption in the
communication between the Profibus
DP network master and the inverter. The
Profibus DP communication interface
went into offline status.
„
Check if the network master is correctly configured and operating
properly.
„
Check for short-circuit or poor contact on the communication
cables.
„
Check if the cables are not misconnected or inverted.
„
Check if the termination resistors with the right value were
installed only at the end of the main bus.
„
Check the network installation in general - cabling, grounding.
A140
Profibus DP Module
Access Error
It indicates error in the access to the
Profibus DP communication module
data.
„
Check if the Profibus DP module is correctly fitted.
„
Hardware errors due to improper handling or installation of the
accessory, for instance, may cause this error. If possible, carry
out tests by replacing the communication accessory.
A163
Signal Fault AI1
4...20 mA
Analog input signal AI1 at 4 to 20 mA or
20 to 4 mA is below 4 to 20 mA.
„
Current signal on the analog input AI1 interrupted or null.
„
Parameterization error on analog input AI1.
A164
Signal Fault AI2
4...20 mA
Analog input signal AI2 at 4 to 20 mA or
20 to 4 mA is below 4 to 20 mA.
„
Current signal on the analog input AI2 interrupted or null.
„
Parameterization error on analog input AI2.
A177
Replace Fan
Alarm to replace the fan
(P045 > 50000 hours).
„
Maximum number of operation hours of the heatsink fan
exceeded.
A211
Drive in Fire Mode
Indicates that the drive is in Fire Mode.
„
The digital input programmed for activating the Fire Mode is
active.
