Siemens F34875

Brand: SiemensModel: SINAMICS G120 CU250S2Error code: F34875

What the Fault Means

Fault: VSM DRIVE-CLiQ (CU): Supply voltage failed

Likely causes

  • The DRIVE-CLiQ communication from the DRIVE-CLiQ component involved to the Control Unit signals that the supply voltage has failed
  • Fault cause: 9 (= 09 hex): The power supply voltage for the components has failed
  • Note regarding the message value: The individual information is coded as follows in the message value (r0949/r2124): 0000yyxx hex: yy = component number, xx = error cause

Solution and Safe First Checks

  1. carry out a POWER ON (switch-off/switch-on).
  2. check the power supply voltage wiring for the DRIVE-CLiQ component (interrupted cable, contacts, ...).
  3. check the dimensioning of the power supply for the DRIVE-CLiQ component.

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
