Digital signal processor

The digital signal processor, usually shortened to DSP, is a processor inside the inverter. Fronius inverters report status code 460 when the reference voltage source that feeds the DSP is running outside its tolerances. Fronius Primo and Symo inverters report status code 461 when there is an error in the DSP data memory. On the Fronius Symo, status code 518 means an internal DSP malfunction, and the inverter shows a warning message on its display.

<!-- review notes

• sentence 1: support check: partial - Passages define DSP as Digital Signal Processor, but none say it is a processor inside the inverter.
• sentence 2: support check: partial - Code 460 with reference voltage source for the DSP outside tolerances is stated (u2, u3), but the passages don't name Fronius, and u1 says 'power source'.
• sentence 3: support check: partial - Code 461 as an error in DSP data memory is stated, but the passages don't mention Fronius or Primo/Symo models.
• sentence 4: support check: partial - Code 518 as an internal DSP malfunction with a warning message on the display is stated, but the Fronius Symo model isn't named in the passages.
• sentence 1: review: partial - The passages only expand DSP as digital signal processor and never say it is a processor inside the inverter. -->
