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.
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.
AC Drive Overtemperature (Alarm, Board) occurs when power unit or board heat sink temperature is high, with limits varying by enclosure size. The manual lists no action for this code.
ID 130 - AC Drive Overtemperature (Fault, Heat Sink) happens when power unit or board heat sinks are too hot, requiring cooling air check. The manual's first action is: “Check the actual amount and flow of cooling air.”
ID 120 - AC Drive Undertemperature (Fault) occurs when heat sink temperature is too low, indicating ambient temperature is too cold for the drive. The manual's first action is: “The ambient temperature is too low for …
ID 100 - Output Phase Supervision indicates no current in one motor phase due to motor/cable malfunction or filter failure. The manual's first action is: “Check the motor cable and the motor.”
Input Phase fault occurs from supply voltage malfunction, faulty fuse, or cable issues, with software-based supervision. The manual's first action is: “Check the supply voltage.”
Undervoltage (Fault) happens when DC link voltage is too low due to insufficient supply voltage or a defective component. The manual lists no action for this code.
System Fault occurs when new licenses are taken into use or removed since the last start-up. The manual lists no action for this code.
