F08501 fault in Siemens G120 Drive indicates a PROFINET Setpoint Timeout. This fault occurs when the drive stops receiving setpoint data from the PROFINET controller within the configured monitoring time. As a result, the drive detects a communication interruption and generates the F08501 fault. Possible Causes: Solutions: Additional Information The F08501 PROFINET Setpoint Timeout faultRead more ⟶

A07991 alarm in Siemens G120 Drive indicates that the Motor Data Identification routine is activated. This means the drive has been configured to perform motor data identification during the next power-on command. The drive uses this procedure to automatically determine motor parameters and optimize motor control performance. This is an alarm, not a fault, andRead more ⟶

CU BUSY on the BOP-2 (Basic Operator Panel 2) of a Siemens G120 drive indicates that the Control Unit (CU) is currently busy processing an operation and is temporarily unable to accept additional commands. This is generally an informational message rather than a fault. Possible Causes: Solutions: Additional Information The CU BUSY message commonly appears:Read more ⟶

F01910 fault in Siemens G120 Drive indicates a Fieldbus Interface Setpoint Timeout. This fault occurs when the drive stops receiving setpoint data from the fieldbus communication interface within the configured monitoring time. As a result, the drive generates a communication timeout fault and may stop operation depending on the configured response. Possible Causes: Solutions: PROFIBUS-SpecificRead more ⟶

F07902 fault in Siemens G120 Drive indicates a Motor Stalled Fault. This means the drive has detected that the motor is unable to rotate or accelerate as expected and has remained in a stalled condition for longer than the delay time configured in p2178. To protect the motor and drive from overheating and excessive current,Read more ⟶

F07901 fault in Siemens G120 Drive indicates a Motor Overspeed Fault. This means the motor speed has exceeded the maximum permissible speed limit configured in the drive. The overspeed condition can occur in either the positive or negative direction of rotation, causing the drive to trip to protect the motor and mechanical system. Possible Causes:Read more ⟶

F07802 fault in Siemens G120 Drive indicates that the Infeed or Power Unit is Not Ready. This means the drive has issued an internal power-on command, but the associated infeed unit or power unit failed to report a ready status within the expected time. As a result, the drive generates the F07802 fault and preventsRead more ⟶

F0001 fault in ABB Drive indicates an Overcurrent Fault. This means the drive has detected motor current exceeding the permissible limit. The fault is generated to protect the inverter power components and motor from damage caused by excessive current. Possible Causes: Solutions: Additional Information The F0001 Overcurrent Fault is one of the most common ABBRead more ⟶

2330 fault in ABB Drive indicates a Short Circuit Fault. This means the drive has detected excessive current caused by a short circuit condition in the motor circuit, output cables, or power components. To protect the inverter and motor from damage, the drive immediately trips and stops operation. Possible Causes: Solutions: Additional Information The 2330Read more ⟶

F2042 fault in Rexroth IndraDrive indicates Encoder 2: Encoder Signals Incorrect. This means the drive has detected abnormal signal amplitude or signal shape from Encoder 2. The drive continuously monitors the encoder’s sine and cosine signals, and if the signals fall outside the permissible range or become distorted enough to cause a position error, theRead more ⟶
