Siemens A30079 fault code meaning

Siemens / A30079

Series: S120-S150

Power unit: DC bus voltage too high relative to input voltage

converter

Meaning: An alarm occurs when the following conditions are met simultaneously: 1. The device input voltage (p0210) decreases. 2. The DC bus voltage is too high relative to the new input voltage. DC bus precharging cannot be completed, as this would damage the converter components.

Series: S200

Power unit: DC bus voltage too high relative to input voltage

servo drive

Meaning: The alarm occurs when both of the following conditions are met: 1. The device input voltage (p0210) decreases. 2. The DC bus voltage is too high relative to the new input voltage. DC bus precharging cannot be completed, as this would damage converter components.

Series: S210

Power unit: DC bus voltage too high relative to input voltage

servo drive

Meaning: The alarm occurs when the following conditions are met simultaneously: 1. The device input voltage (p0210) has decreased. 2. The DC bus voltage is too high relative to the new input voltage. DC bus precharging cannot be completed, as this would damage the converter components.
