Siemens A07891

Brand: SiemensModel: SINAMICS G120 CU250S2Error code: A07891

What the Fault Means

Alarm: Drive: Load monitoring pump/fan blocked

Likely causes

  • The load monitoring is configured for a pump or fan (p2193 = 4, 5)
  • The monitoring function detects when the pump/fan is blocked
  • It is possible that the blocking torque threshold (p2168) is set too low (e.g
  • heavy duty starting)

Solution and Safe First Checks

  1. check whether the pump/fan is blocked, and if blocked, then resolve the problem.
  2. check that the fan can freely move, and if necessary, resolve the problem.
  3. adapt the parameterization corresponding to the load (p2165, p2168)..

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