Siemens A07401 fault code meaning

Series: G110M, G115D, G120-CU240B-E-2, G120-CU250S-2, G120C, S120-S150

Drive: Maximum DC bus voltage controller disabled

converter

Meaning: The Vdc_max controller cannot keep the DC bus voltage (r0070) below the limit values (r1242, r1282) and is therefore disabled. - The input voltage remains above the voltage specified for the power unit. - During regenerative operation, the motor is continuously driven by the load.

Series: G200, G210, G210X, G220

Drive: Maximum DC bus voltage controller disabled

converter

Meaning: The Vdc_max controller cannot keep the DC bus voltage (r0070) below the limits (r1242, r1282) and therefore disables itself. - The mains voltage remains above the voltage specified for the power unit. - During regenerative operation, the motor is continuously driven by the load.
