Description
Current measurement circuit is measuring a wrong
value for null current.
Alarm related to the PTC temperature sensor installed
in the motor.
Note:
- It may be disabled by setting P0351 = 0 or 2.
- It is required to set the analog input/output to the
PTC function.
Indicates that the inverter stopped receiving valid
messages within a certain time interval.
Note:
It may be disabled by setting P0314 = 0.0 s.
Alarm that indicates interruption of the Anybus-CC
communication.
Alarm that indicates an access error to the
Anybus-CC communication module.
Alarm indicating that the power supply was not
connected to the CAN controller.
Inverter CAN interface has entered into the bus-off
state.
Alarm that indicates a communication error.
Network master has entered into the idle state.
I/O connection timeout - DeviceNet communication
alarm.
It indicates that the inverter received a command
from the Profibus DP network master to enter the
clear mode.
It indicates an interruption in the communication
between the Profibus DP network master and the
inverter.
It indicates an error in the access to the Profibus DP
communication module data.
Overspeed fault.
It is activated when the real speed exceeds the value
of P0134 x (100 % + P0132) for more than 20 ms.
FLASH Memory Module fault (MMF-03).
Alarm indicating that the internal air temperature is
too high.
Note:
It may be disabled by setting P0353 = 1 or 3.
Internal air overtemperature fault.
Undertemperature fault, measured at the IGBTs
temperature sensors.
Safety Stop relay fault.
Possible Causes
Defect in the inverter internal circuitry.
Excessive load at the motor shaft.
Excessive duty cycle (too many starts/stops per minute).
Surrounding air temperature too high.
Loose connection or short-circuit (resistance < 100 Ω) in the
wiring connected to the motor termistor.
Motor termistor is not installed.
Blocked motor shaft.
Check the wiring and grounding installation.
Make sure the inverter has sent a new message within the
time interval set at P0314.
PLC entered into the idle state.
Programming error. Master and slave set with a different
number of I/O words.
Communication with master has been lost (broken cable,
unplugged connector, etc.).
Defective, unrecognized, or improperly installed Anybus-CC
module.
Conflict with a WEG option board.
Broken or loose cable.
Power supply is off.
Incorrect communication baud-rate.
Two nodes configured with the same address in the network.
Wrong cable connection (inverted signals).
Communication problems.
Wrong master configuration/settings.
Incorrect configuration of the communication objects.
PLC in IDLE mode.
Bit of the PLC command register set to zero (0).
One or more allocated I/O connections have entered into the
timeout state.
Verify the network master status, making sure it is in execution
mode (Run).
Refer to the Profibus DP communication manual for more
information.
Verify whether the network master is correctly configured and
operating normally.
Verify the network installation in a general manner - cable
routing, grounding.
Refer to the Profibus DP communication manual for more
information.
Verify whether the Profibus DP module is correctly fit into the
slot 3.
Refer to the Profibus DP communication manual for more
information.
Wrong settings of P0161 and/or P0162.
Problem with the hoist-type load.
Defective FLASH memory module.
FLASH memory module is not connected properly.
Surrounding air temperature too high (> 45 °C (113 °F)) and
excessive output current.
Defective internal fan.
High temperature (> 45 ºC (113 °F)) inside the cabinet.
Surrounding air temperature ≤ -30 °C (-22 °F) .
It was only applied +24 Vdc to one STO input (STO1 or
STO2).
One of the relays is defective.
