Weg F0150 Fault Alarm

I've got an older Weg drive that occasionally throws out a F0150 Fault, anyone have any detailed info on the F0150 alarm / fault?

It does not happen every day, the motor can run for days or even a few weeks error free. Thanks!

The F0150 Alarm is an overspeed fault. If you are only getting the fault occasionally, maybe it related to the loading of the motor and not necessarily the Weg inverter. You will have to look at the big picture.

I forgot to ask, what model or series inverter was this?

It is a Weg CFW Inverter, CFW700 to be more specific.

Weg Alarm List
Here's a pretty good list if Weg alarms and faults that should be compatible with Weg CFW drives. This may help you out.

F0006: Input Voltage Imbalance or Phase Loss - The mains voltage imbalance is too high or phase loss at the supply line has occurred. Note: This fault may not occur if the load at the motor shaft is too low or nonexistent. P0357 sets the time for the trip, and P0357 = 0 disables this fault.

F0021: DC Link Undervoltage - A DC link undervoltage condition has occurred.

F0022: DC Link Overvoltage - A DC link overvoltage condition has occurred.

A0046: High Load at the Motor - It is the motor overload alarm. Note: It can be disabled by setting P0348 = 0 or 2.

A0047: IGBT Overload Alarm - It is the IGBT overload alarm.

F0048: IGBT Overload Fault - It is the IGBT overload fault.

A0050: IGBT High Temperature - The NTC temperature sensors located in the IGBTs detected a high temperature alarm.

F0051: IGBT Overtemperature - The NTC temperature sensors located in the IGBTs detected a high temperature fault.

F0067: Inverted Encoder/ Motor Wiring - Fault related to the phase relationship between the encoder signals, if P0202 = 5 and P0408 = 2, 3 or 4.

F0070: Overcurrent/Short-circuit - An overcurrent or a short-circuit at the output, at the DC link or at the braking resistor, has occurred.

F0071: Output Overcurrent - An output overcurrent has occurred.

F0072: Motor Overload - The motor overload protection has tripped.

F0074: Ground Fault - A ground fault occurred either in the cable between the inverter and the motor or in the motor itself.

F0078: Motor Overtemperature - Fault related to the PTC temperature sensor installed in the motor. Note: - It can be disabled by setting P0351 = 0 or 3. - An analog input and an analog output must be set for the PTC function.

F0079: Encoder Signal Fault - Lack of encoder signals. Note: Detection performed only by software. The fault can be disabled by means of parameter P0358.

F0080: CPU Watchdog - Microcontroller watchdog fault.

F0084: Auto-Diagnosis Fault - Auto-Diagnosis Fault.

A0090: External Alarm - External alarm monitored through a digital input. Note: It is necessary to program a digital input for “No external alarm”.

F0091: External Fault - External fault monitored through a digital input. Note: It is necessary to program a digital input for “No external fault”.

A0098: Activate General Enable - General enable signal is missing during the self-tuning.

F0099: Invalid Current Offset - The current measurement circuit is presenting an abnormal value for null current.

A0110: High Motor Temperature - Fault detected through PTC type temperature sensors installed in the motor. Note: - It can be disabled by setting P0351 = 0 or 2. - An analog input and an analog output must be set for the PTC function.

A0128: Serial Communication Timeout - It indicates that the inverter stopped receiving valid telegrams during a certain period. Note: It can be disabled by setting P0314 = 0.0 s

A0133: CAN Interface without Power Supply - It is the alarm indicating that the power supply is missing at the CAN controller.

A0134: Bus Off - The inverter CAN interface has entered the buss off state.

A0135: CANopen Communication Error - It indicates a communication error alarm.

A0136: Idle Master - The network master has entered the idle state.

A0137: DeviceNet Connection Timeout - It is the alarm indicating timeout of the DeviceNet I/O connections.

A0138: Profibus DP Interface in Clear Mode - It indicates that the inverter received a command from the Profibus DP network master to enter the clear mode.

A0139: Offline Profibus DP Interface - It indicates an interruption in the communication between the Profibus DP
network master and the inverter.

A0140: Profibus DP Module Access Error - It indicates an error in the access to the Profibus DP communication module data.

F0150: Motor Overspeed - Overspeed fault. It trips when the actual speed exceeds the value of P0134 x (100 % + P0132) / 100% for more than 20 ms

F0151: FLASH Memory Module Fault - FLASH Memory Module (MMF-01) fault.

A0152: High Internal Air Temperature - This alarm indicates that the internal air temperature is too high. Note:
It can be disabled by setting P0353 = 1 or 3.

F0153: Internal Air Overtemperature - It indicates internal air overtemperature fault.

F0156: Undertemperature - The temperature sensors located in the IGBTs or in the rectifier detected a low temperature, below -30 °C ( -22 °F), fault.

F0157: Parameter Table Data Loss - There was a problem during the initialization, during the parameter table loading routine. Some recent parameter modifications may have been lost.

F0158: Parameter Table Fault - There was a problem during the initialization, during the parameter table loading routine. All the parameters were lost and the factory settings were loaded.

A0159: Incompatible HMI - Incompatible HMI

F0160: Safety Stop Relays - STO function (Safe Torque Off) relay fault.

Thanks for the Weg Alarm list! Although I'm still trying to figure out a pattern for my alarms, I may have something else wrong in my system causing uneven loading, I'm not sure yet.
