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.
Digital input parameter fault indicates that digital inputs P052–P055 are misconfigured and require correction of their settings. The manual's first action is: “Change the settings of digital inputs P052 to P055.”
Digital input parameter fault indicates that digital inputs P052–P055 are misconfigured and require correction of their settings. The manual's first action is: “Change the settings of digital inputs P052 to P055.”
Parameter fault P012/P013 occurs when the value of P012 is greater than or equal to P013, requiring adjustment to ensure P012 < P013. The manual's first action is: “Set parameter P012 < P013.”
Parameter fault P006 occurs when fixed frequency or motor potentiometer settings are not properly configured on digital inputs. The manual's first action is: “Parameterise fixed frequency(ies) and/or motor potentiomet…
Failure to start on the fly indicates that the inverter cannot initiate operation under current settings, possibly due to incorrect P016 value. The manual's first action is: “Try setting P016 to a different value.”
Programme fault occurs when software or firmware is corrupted, requiring restart of power to reset the system. The manual's first action is: “Switch off power and switch on again.”
Internal interface fault indicates a hardware communication issue within the inverter, resolved by restarting power. The manual's first action is: “Switch off power and switch on again.”
Initialisation fault occurs when the parameter set is corrupted or incomplete, requiring resetting P009 to '0000' before power down. The manual's first action is: “Check the entire parameter set. Set P009 to '0000' be…
Undervoltage indicates that the supply voltage is too low for normal operation of the Siemens MICRO MASTER and MIDI MASTER inverter. The manual's first action is: “Check the supply voltage.”
USS protocol timeout occurs when communication with the bus master fails, possibly due to serial interface issues or incorrect settings for P091–P093. The manual's first action is: “Check the serial interface. Check t…
Mains phase missing (for 3-phase units) indicates that one of the three phases in the power supply is absent or disconnected. The manual's first action is: “Check the mains supply and correct.”
Inverter or motor overtemperature by I²t calculation occurs when ambient temperature is too high or airflow is restricted, causing current to exceed P083 limits. The manual's first action is: “Check that the ambient t…
Motor overheating (monitoring with PTC) indicates excessive heat detected by the PTC sensor, possibly due to faulty connections or missing PTC configuration. The manual's first action is: “Check whether the motor is o…
Overload occurs when the motor is working beyond its rated capacity, which may require increasing the maximum frequency for high-slip motors. The manual's first action is: “Check whether the motor is overloaded. Incre…
Overcurrent happens when the motor draws more current than the inverter can handle, possibly due to mismatched power or cable issues. The manual's first action is: “Check whether the motor power corresponds to the inv…
