Description
Overload on the dynamic braking resistor fault.
Fault related to PTC temperature sensor installed
on the motor.
Note:
- It may be disabled by setting P0351 = 0 or 3.
- It is necessary to program analog input and output
for PTC function.
Encoder signals missing fault.
Watchdog fault on the microcontroller.
Fault in the copy of parameters.
Self-Diagnose Fault.
Communication fault of the HMI with the control
board.
External alarm via DI.
Note:
- It is necessary to program DI for "without external
alarm".
External fault via DI.
Note:
- It is necessary to program DI for "without external
fault".
Current measurement circuit presents a value out
of the standards for zero current.
Alarm related to PTC temperature sensor installed
on the motor.
Note:
- It can be disabled by setting P0351 = 0 or 2.
- It is necessary to program analog input and
output for PTC function.
It indicates that the inverter stopped receiving valid
telegrams within a certain period.
Note:
- It can be disabled by setting P0314 = 0.0 s.
Alarm that indicates interruption in the Anybus-CC
communication.
Alarm that indicates error of access to the Anybus-
CC communication module.
Alarm of power supply missing on the CAN controller.
CAN peripheral of the inverter went to the bus off
status.
Alarm that indicates communication error.
Network master went to the idle state.
Alarm of timeout on the DeviceNet I/O connections.
Troubleshooting and Maintenance
Possible Causes
Load inertia too high or deceleration ramp too
„
fast.
Load on the motor shaft is too high.
„
Values of P0154 and P0155 programmed
„
incorrectly.
Load on the motor shaft is too high.
„
Load cycle is too high (high number of starts and
„
stops per minute).
High ambient temperature around the motor.
„
Poor contact or short circuit (resistance <60 Ω)
„
on the wiring connected to the motor thermistor.
Motor thermistor not installed.
„
Motor shaft locked.
„
Wiring between encoder and encoder interface
„
accessory interrupted.
Encoder is defective.
„
Electric noise.
„
Attempt to copy parameters from the HMI to the
„
inverter with incompatible software versions.
Defect on the inverter internal circuits.
„
Poor contact on the HMI cable.
„
Electric noise on the installation.
„
Wiring in the DI1 to DI8 inputs open (programmed
„
for "without external alarm").
Wiring in the DI1 to DI8 inputs open (programmed
„
for "without external fault").
Defect on the inverter internal circuits.
„
Overload on the motor shaft.
„
Load cycle too high (high number of starts and
„
stops per minute).
High ambient temperature around the inverter.
„
Motor thermistor not installed.
„
Motor shaft locked.
„
Check the installation of cables and grounding.
„
Make sure the master sent a new telegram in a
„
period of time shorter than the setting in P0314.
PLC went to the Idle state.
„
Programming error. Number of I/O words
„
programmed on the slave is different from the
setting on the master.
Loss of communication with the master (broken
„
cable, connector disconnected, etc.).
Anybus-CC module defective, not recognized or
„
incorrectly installed.
Conflict with WEG optional board.
„
Broken or disconnected cable.
„
Power supply turned off.
„
Incorrect baud rate.
„
Two slaves on the network with the same
„
address. Error in the cable assembly (inverted
signals).
C o m m u n i c a t i o n p r o b l e m s . I n c o r r e c t
„
programming of the master.
Incorrect configuration of the communication
„
objects.
PLC switch in the idle position.
„
Bit of the PLC command register in zero (0).
„
One or more allocated I/O connections went to
„
the timeout status.
