Kone V3F25/18 drive

Emergency stop or error detected by the V3F25/18 drive diagnostics. This is a general fault indicating that a specific fault code should be present to determine the root cause.

An emergency stop is initiated, and the V3F25/18 drive is prevented from operating until the fault is corrected. This indicates that the current drawn by the motor has exceeded its programmed limit.

An emergency stop is initiated by the V3F25/18 drive. This fault indicates a problem within the braking resistor circuit, such as a damaged resistor or issues with its electrical connections.

The V3F25/18 drive prevents further operation until the motor temperature returns to a safe level. This indicates that the motor has exceeded its thermal operating limits.

An emergency stop occurs, and the V3F25/18 drive is prevented from starting until the fault is corrected. This indicates an issue with the supply AC voltage to the drive's intermediate DC bus, either being excessively low or high.

The V3F25/18 drive is prevented from operating until this fault is corrected. This indicates a general issue with the inverter's internal operation or its external control signals and feedback.

The elevator controller prevents the drive, although the V3F25/18 drive itself may allow driving. This indicates an issue with the Load Weighing Device (LWD) mechanical adjustment, parameter settings, or the actual load in the car.

The shaft setup for the V3F25/18 drive is not completed. This indicates an issue with the physical positioning or alignment of the vanes or magnets and their corresponding switches, leading to insufficient overlap between switches 61:U and N.

The shaft setup for the V3F25/18 drive is not completed. This indicates a problem with the synchronisation switch, likely related to its physical positioning or the air gap between the switch and the magnet.

The shaft setup for the V3F25/18 drive is not completed. This indicates that the measured or configured physical distance between floors is too short, likely due to incorrect vane or switch positioning.

The shaft setup for the V3F25/18 drive is not completed. This indicates an issue with the physical positioning of the vanes, resulting in excessive overlapping of switches 61:U and N at the topmost floor.

The shaft setup for the V3F25/18 drive is not completed. This indicates that the system has registered an incorrect number for the top floor, likely due to an incomplete or erroneous shaft setup procedure.

The V3F25/18 drive will not run in normal drive mode; only RDF (machine room inspection drive in North America) and inspection drives are possible. This fault indicates that the initial shaft setup procedure has not been completed.

The MXTORQ (6_9) parameter shows '-', '--', or an emergency stop occurs during acceleration on the V3F25/18 drive. This indicates that the motor torque has exceeded the configured maximum limit.

An emergency stop occurs, and the elevator will not start with the V3F25/18 drive. This fault indicates that the safety relay circuit is in an open state, preventing normal operation.

An emergency stop or a main contactor time out (2 seconds) occurs with the V3F25/18 drive. This fault indicates that the main contactor failed to energize within the expected timeframe.

Normal drive operation is prevented by the V3F25/18 drive. This fault indicates that the load values for the Load Weighing Device (LWD) have not been properly set, requiring a minimum of two values.

The elevator stops, performs a correction drive, and returns to the bottom floor with the V3F25/18 drive. This indicates a fault with the V1 NTS (Normal Terminal Stopping) switch.

The elevator stops, performs a correction drive, and returns to the bottom floor with the V3F25/18 drive. This indicates a fault with the V1 NTS (Normal Terminal Stopping) switch.

Position is lost, and the elevator is stopped by the NTS (Normal Terminal Stopping) switches using the V3F25/18 drive. This fault is primarily related to a loss of elevator position.
