This fault occurs in the ATV310 drive due to excessive regenerative energy returned from the motor to the drive, causing the DC bus voltage to rise above its permissible limit. This is typically triggered by sudden deceleration or a high inertia load application.

For the ATV310 drive, this fault indicates that the current drawn by the motor has exceeded the drive's maximum permissible current limit. This is often caused by incorrect motor control parameters, an excessively high load or inertia, or mechanical binding in the driven system.

This fault occurs when the Drive thermal state (809) exceeds 118%. It indicates that the internal temperature of the drive has risen above its safe operating limits, potentially leading to derating or damage to power components.

For the ATV310 drive, this fault indicates that the current drawn by the motor, as monitored by the drive, suggests an overload condition originating from the mechanical process or application itself. It signifies that the mechanical load on the motor is too high.

The drive displays an F013 fault when the Motor thermal state (808) exceeds 118%. This indicates that the motor is operating beyond its safe thermal limits, risking damage to the motor windings.

For the ATV310 drive, this fault is detected when one phase on the drive's output to the motor is lost. This can be caused by poor electrical connections, damaged motor cables, or issues with a downstream contactor.

This ATV310 fault is detected when all three phases on the drive's output to the motor are lost. Common causes include a disconnected motor, a motor with insufficient power relative to the drive, an open output contactor, or transient instability in the motor current during operation.

This ATV310 fault occurs when the incoming line voltage supplied to the drive is excessively high. This can be triggered at power-on (10% over maximum acceptable voltage) or when idle (20% over maximal line supply), or by a disturbed mains supply.

For the ATV310 drive, this fault is detected when one or more phases of the main line supply to the drive are lost or significantly unbalanced. This protection primarily operates when the drive is under load and can be triggered by blown fuses or incorrect supply configuration (e.g., a 3-phase drive on a single-phase supply).

This ATV310 fault is triggered by a short-circuit or ground fault at the drive output, or within the motor itself. It can occur while the drive is running, due to motor switching, or from significant current leakage when multiple motors are connected in parallel.

This ATV310 fault indicates a ground fault condition detected in the system, typically at the drive output or within the motor/cabling. This poses a safety risk and can lead to equipment damage if not promptly addressed.

This ATV310 fault indicates an internal power component short circuit, specifically within the IGBTs (Insulated Gate Bipolar Transistors) of the drive's inverter section. This critical hardware failure is typically detected at power-on and requires specialized repair.

This ATV310 fault detects a short-circuit condition at the drive's output, impacting the motor or cabling. It can be triggered either at the run command or during a DC injection command, especially if parameter 608 (IGBT Test) is set to 01.

For the ATV310 drive, this fault occurs when communication on the Modbus network connected to the drive is interrupted. This can be due to physical connection issues, incorrect communication settings, or an improperly configured Modbus time-out.

This ATV310 fault indicates an interruption in communication with the external display terminal (HMI). This prevents control and monitoring of the drive via the HMI interface.

For the ATV310 drive, this fault indicates that the motor or application is operating at a speed significantly higher than expected, exceeding the drive's configured limits, potentially more than 10% above the Top frequency (parameter 308). This can be caused by control instability, high inertia loads, or incorrect speed loop parameters.

This ATV310 fault indicates that the internal temperature of the drive's IGBTs (Insulated Gate Bipolar Transistors) has reached an excessively high level. This condition is critical and is influenced by ambient temperature, motor load, and drive switching frequency, risking damage to the drive if not addressed.

This ATV310 fault occurs when the drive's auto-tuning function fails to complete successfully. This can be caused by the motor not being properly connected, a motor phase loss during the tuning process, using a special motor type incompatible with standard autotuning, or the motor rotating during the tuning procedure.

This fault is detected when the motor current drops below the Application Underload threshold (211) for a duration longer than the Application underload time delay (210). This condition indicates that the motor is running with insufficient load, and detection is active only during steady-state operation.

The Undervoltage fault occurs when the line supply voltage to the drive is too low or experiences a transient dip. This can lead to unstable drive operation or shutdown to protect internal components.

This fault indicates that the drive's configuration is inconsistent. It can occur if an HMI block from a drive with a different rating is installed, or if the customer parameters currently loaded are not valid for the drive.

This fault signifies that the configuration loaded into the drive, typically via the bus or a communication network, is inconsistent. It can also be triggered if the configuration upload process was interrupted or did not complete successfully.

For the ATV310 drive, this fault is detected if Analog input AI1 is configured for current (parameter 204.1 > 3 mA) and the actual analog input current falls below 2 mA. This indicates a loss of signal from the connected sensor or a wiring integrity issue at the input.

This fault indicates an incompatibility between the connected display terminal and the drive. Specifically, the brand or type of the drive does not match that of the display terminal, preventing proper operation and communication.

This fault indicates an abnormality detected within the Random Access Memory (RAM) of the display terminal. This suggests an internal memory corruption or hardware issue affecting the display terminal's ability to process and store temporary data.

This fault indicates an abnormality detected within the Read-Only Memory (ROM) of the display terminal, typically identified through a checksum calculation error. This suggests an internal data corruption or hardware issue within the display terminal's ROM.
