SEW Eurodrive MOVIFIT

This fault indicates an overcurrent condition on the inverter output. It is typically caused by a short circuit in the connection between the inverter and the motor, or a short circuit within the motor winding itself. Excessive current flow from the inverter can lead to damage if not addressed.

This fault signifies that the output current to either drive 1 (monitored by P300/P301) or drive 2 (monitored by P310/P311) has exceeded its configured cut-off limit for the parameterized delay time. This protective shutdown is often caused by excessive mechanical load on the motor, a short circuit in the motor windings or cables, or improperly set overcurrent parameters. Persistent overcurrent can lead to motor winding damage, thermal stress on cables, and potential failure of the MOVIFIT unit's output stage. If left unaddressed, this could result in costly motor replacement or unit downtime.

This fault can signify one of two issues: either a thermal overload of the motor due to factors like high ambient temperature, inadequate heat dissipation, or excessive mechanical load; or an overcurrent condition within the brake chopper circuitry. Both conditions indicate a risk of component damage.

A phase failure has been detected in the supply system. This fault indicates a loss of one or more phases in the input power supply, and it is detectable only when the drive is operating under load. Continued operation with a phase failure can damage the motor or inverter.

This fault indicates a loss of one line phase (L1, L2, or L3) either during initial network detection or after the network has been successfully established. Note that the failure of two line phases does not trigger this error, but rather a 'Not ready, 24V' state without an explicit error message. Prolonged operation with a missing phase can lead to motor damage, unit malfunction, and potential safety hazards due to unbalanced loads. It is crucial to resolve this promptly to prevent further component stress.

The DC link voltage has exceeded its permissible limit. Potential causes include a ramp time set too short, incorrect wiring or internal resistance of the brake coil/braking resistor, thermal overload in the braking resistor, or an invalid mains voltage range. High DC link voltage poses a risk to the inverter's components.

Speed monitoring has been triggered, indicating that the load on the drive is too high, causing the motor speed to deviate beyond acceptable limits. This protective function prevents the motor from operating outside its designed speed range under excessive load.

This fault indicates incorrect startup or parameter settings, potentially configured via MOVITOOLS® MotionStudio. The unit's initial configuration is not valid, preventing proper operation.

This fault encompasses two distinct startup issues. In 'dual-motor operation', it signifies an incorrect line phase sequence, preventing motors from running in the intended clockwise direction. In 'single-motor operation', it means an unexpected current (over 10% IN,unit) is detected on drive 2, usually due to incorrect wiring, such as a drive connected to X9 or two drives being present when only one is allowed. Both scenarios prevent proper unit startup and operation, risking mechanical stress to connected equipment or uncontrolled motor movement.

This fault indicates either the unit's heatsink temperature has exceeded its permitted limit (sub-error 1-2) or the total utilization of both drives in dual-motor operation is excessively high (sub-error 4-5). Causes include high ambient temperatures, insufficient ventilation, or excessive mechanical load on the drives. Overheating and overutilization can lead to component degradation, reduced lifespan of the MOVIFIT unit, and potential permanent damage to power electronics if not resolved promptly.

The supply voltages 24V_C and/or 24V_P are too low, falling below the required operating threshold for the unit's electronics. This inadequate voltage supply can lead to unpredictable behavior or complete unit shutdown.

An internal CPU fault has occurred within the unit. This indicates a general internal processing error, which might be transient or indicate a more serious hardware issue.

This fault indicates a general error within the unit's Central Processing Unit, signaling an internal malfunction of the control electronics. While it can sometimes be a transient issue, it may also point to a deeper hardware defect within the unit's core processing components. Repeated occurrences of this error can lead to unpredictable unit behavior, loss of control, or complete operational failure, potentially causing process interruptions.

A fault occurred when accessing the EEPROM, indicating an issue with non-volatile memory read/write operations. This can affect unit parameters and configuration data.

This fault is triggered when a low signal is detected on a specific terminal that has been configured for the '/External fault' function, primarily when the MOVIFIT unit operates as an SBUS slave. This indicates an issue with an external device connected to this terminal, signaling a fault condition from that external source. The low signal could be due to wiring issues, a faulty sensor, or an active fault in the connected external equipment, causing the MOVIFIT unit to stop operation.

The TF (Thermal Fault) input has been triggered. This indicates that an external thermal protection device, such as a motor thermistor, has detected an over-temperature condition and activated the fault input.

This fault indicates a general error within the unit's Central Processing Unit, signaling an internal malfunction of the control electronics. While it can sometimes be a transient issue, it may also point to a deeper hardware defect within the unit's core processing components. Repeated occurrences of this error can lead to unpredictable unit behavior, loss of control, or complete operational failure, potentially causing process interruptions.

This fault indicates that the combined output current from both drive 1 and drive 2 has exceeded 180% of the unit's nominal current (IN,unit). This represents a severe overload condition, potentially leading to immediate shutdown to protect the power electronics and prevent damage to the MOVIFIT unit. It can be caused by excessive mechanical load or by simultaneously enabling both drives when their combined current draw exceeds the unit's capacity. Unresolved, this can lead to premature failure of the drive unit.

This fault indicates that the MOVIFIT unit was unable to automatically detect or recognize the sequence of the incoming three-phase power supply during its initialization phase. This prevents the unit from starting correctly and is typically due to incorrect wiring of the grid connection (L1, L2, L3). An unrecognized phase sequence can lead to motors rotating in the wrong direction, damage to mechanical components, or unit malfunction, requiring immediate correction before operation.

This fault indicates a timeout in the cyclical communication over the CAN bus, meaning the unit is not receiving expected data from, or sending data to, another device on the CAN network within the specified time window. This can interrupt critical control and data exchange, leading to system halts, unpredictable behavior, or loss of synchronized operation. It's often related to wiring, termination, baud rate, or configuration issues on the bus, and can cause significant process downtime.

This fault indicates an issue with the start condition, specifically relevant in hoist operation mode, or an open circuit in the output. It could be due to a phase failure in the motor lead preventing proper startup or operation.

This fault indicates an issue with an open output or the start condition. It could be due to a phase failure in the motor lead, preventing the drive from operating correctly or detecting its output.

The motor has experienced thermal overload. This can be caused by high ambient temperature, inadequate heat dissipation around the motor, or excessive mechanical load on the motor, leading to its operating temperature exceeding safe limits.

The brake coil has experienced thermal overload, is defective, or is connected incorrectly. This can be triggered by a ramp time set too short, an issue identified during brake inspection, or an incorrect combination of the drive (brake coil) and MOVIFIT®-FC frequency inverter. It indicates a problem with the braking system's integrity or control.

This fault indicates an incorrect assignment between the motor and the inverter, or an invalid DIP switch setting. The unit cannot properly detect or configure its output stage, preventing correct motor control.

This fault indicates a permanent hardware defect in the unit's EEPROM (Electrically Erasable Programmable Read-Only Memory), suggesting the memory chip itself is faulty and likely beyond a simple reset or re-parameterization. A defective EEPROM will prevent the unit from reliably storing or retrieving critical configuration data, making consistent and reliable operation impossible. This is a severe hardware failure that typically requires unit replacement.

An error occurred during data transmission or copying process. This could happen during parameter transfer or other data-intensive operations, indicating corrupted or incomplete data writes.
