Siemens 028 fault code meaning

Series: SIMODRIVE 611U

Actual current sensing during power-up

servo drive

Meaning: When the current actual value sensing runs up, or in cyclic operation at pulse inhibit, a 0 current is expected. The drive system then identifies that no currents are flowing (excessive deviation to the theoretical center frequency). It is possible that the hardware for the current actual value sensing is defective.
