Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
The safe Off signal is not allowing the drive to enter READY state, possibly due to safety configuration switch being installed. The manual's first action is: “Reset the fault and restart the drive.”
The ATEX thermistor has detected an overtemperature condition. The manual's first action is: “Reset the fault. Check the thermistor and its connections.”
Start-up Prevented happens when drive cannot start due to software updates, parameter changes, or file modifications affecting operation. The manual's first action is: “Reset the fault and stop the drive.”
Motor Control Fault occurs when rotor moves during identification or new angle disagrees with previous value, requiring restart. The manual's first action is: “Reset the fault and restart the drive.”
Motor Control Fault occurs during start angle identification if rotor moves or new angle doesn’t match old value, specific to customer applications. The manual's first action is: “The rotor moves during identification.”
Power Overload (Short-time Supervision) happens when drive power exceeds its rated capacity. The manual's first action is: “Decrease the load.”
Unbalance (Alarm) occurs due to current imbalance between power units, requiring installation and motor cable inspection. The manual's first action is: “Check the installation and the motor cables.”
Unbalance happens when DC voltage is unbalanced between power units, indicating cable issues. The manual's first action is: “Check the DC link cables between the power units.”
Unbalance occurs when current is unbalanced between power units, requiring cable and connection checks. The manual's first action is: “Check the motor cables and connections.”
Motor Underload indicates insufficient load or parameter/filter issues causing underload condition. The manual's first action is: “Check the load.”
Motor Overtemperature happens due to excessive load on the motor, triggering thermal protection. The manual's first action is: “Decrease the motor load. If there is no motor overload, check the motor thermal protectio…
Motor Stall occurs when the motor has stalled during operation. The manual's first action is: “Check the motor and the load.”
Overvoltage Protection Circuit Temperature (Fault) happens when output capacitance is too high or there’s a ground fault in the floating network. The manual lists no action for this code.
Overvoltage Protection Circuit Temperature (Alarm) occurs due to excessive output capacitance or ground fault in floating network. The manual lists no action for this code.
AC Drive Overtemperature (Fault) happens when auxiliary temperature of the power unit is too high. The manual lists no action for this code.
