Siemens A06800 fault code meaning

Siemens / A06800

Series: G220

Infeed: Maximum steady-state DC bus voltage reached

converter

Meaning: The DC bus voltage setpoint has reached the maximum steady-state voltage set in p0280. The modulation index reserve controller increases the DC bus voltage for the following reasons: - Modulation index reserve too low (p3480). - Mains voltage too high. - Input voltage setting too low (p0210).

Series: S120-S150

Infeed: Maximum steady-state DC bus voltage reached

converter

Meaning: The DC bus voltage setpoint has reached the maximum steady-state voltage configured in p0280. The DC bus voltage is increased by duty cycle reserve control for the following reasons: - Duty cycle reserve too low (p3480). - Input voltage too high. - Input voltage setting too low (p0210). - Line reactive current setpoint too large.
