Siemens alarm F30020: Power unit: Configuration not supported
SINAMICS S120 drive fault · SINAMICS S120
What it means
A configuration was requested that the power unit cannot execute. The hex fault value distinguishes cases such as unsupported autonomous operation, impermissible DRIVE-CLiQ timing, a PM260 with outdated PS-ASIC version, a CU/CUA pulled before initialization finished, an unsupported CU-to-power-unit combination, or unsupported higher current-controller dynamics. Mostly a commissioning/configuration error rather than a spontaneous failure.
Likely causes
- Control Unit or CUA removed from the Power Module at boot
- CU inserted on a different Power Module than originally paired
- firmware/topology mismatch causing invalid DRIVE-CLiQ timing
- PM260 power module with unsupported PS-ASIC version
- higher current-controller dynamics selected on incompatible hardware
Triage note: Decode r0949 as yyyyxxxx hex (xxxx = cause); see p0115, p1231, p1810.
