Siemens A30256 fault code meaning
Siemens / A30256
Series: G200, G210, G210X
Power unit: I2t overload (AC
converter
Meaning: The alarm threshold for power unit I2t overload (95%) has been exceeded. This triggers the response set in p0290. See also: r0036 (Power unit overload)
Possible causes

Series: S200
Power unit: I2t overload (AC
servo drive
Meaning: The overload alarm threshold for power unit I2t on the AC side has been exceeded. The output current and output frequency are reduced according to the selected overload response. Reducing the output current does not sufficiently alleviate power unit overheat, so the temperature continues to rise to the power unit overload trip threshold, causing fault F30005.

Series: S210
Power unit: I2t overload (AC
servo drive
Meaning: The alarm threshold for overload of power unit I2t on the AC side has been exceeded. Depending on the selected overload response, the output current and output frequency are reduced. Reducing the output current does not sufficiently alleviate power unit overheating, so the temperature continues to rise to the power unit overload trip threshold and fault F30005 occurs.

Power unit: I2t overload (AC
converter
Meaning: The alarm threshold for I2t overload of the power unit on the AC side has been exceeded. The output current and output frequency are reduced according to the selected overload response. Reducing the output current cannot sufficiently alleviate power unit overheating, so the temperature continues to rise to the power unit overload trip threshold and fault F30005 occurs.
