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.
One of the three mains supply phases was or still is interrupted The manual's first action is: “Check mains phases 380V-20% to 480V+10% or 200...240V ± 10% respectively, is any of the phases too weak?”
D.C. link undervoltage (charging error) indicates input voltage is too low. The manual's first action is: “Check mains voltage 380V-20% ... 480V+10% or 200...240V ± 10% respectively”
D.C. link overvoltage has occurred The manual's first action is: “Reduce recovered energy by providing a brake resistor”
Module overcurrent error signal from module The manual's first action is: “Short-circuit or ground fault at inverter output”
Inverter overcurrent condition detected by the system The manual's first action is: “Avoid sustained inverter overload”
The motor has overheated due to the PTC resistor triggering. The manual's first action is: “Reduce load on the motor”
The inverter has detected an overtemperature condition. The manual's first action is: “Reduce ambient temperature (to <40°C)”
