I have a question regarding frequency converters for those who are more experienced: What factors determine the Hz value displayed by a frequency converter (other than the set value of the frequency signal for the pump)? For example, if the frequency signal for two identical pumps is set to 50% at the same time, why do they show different Hz values? Are there any other reasons for these issues besides the errors shown on the instruments?

50% is a process parameter, not a frequency

The signal frequency displayed on the inverter is the output frequency. It might be that the source frequency has changed. But the frequency is fixed. I don’t understand; please explain!
