System runtime

By evaluating the system runtime of the inverter, you can decide when you should replace
components subject to wear in time before they fail - such as fans, motors and gear units.
Principle of operation
The system runtime is started as soon as the Control Unit power supply is switched-on.
The system runtime stops when the Control Unit is switched off.
The system runtime comprises r2114[0] (milliseconds) and r2114[1] (days):
System runtime = r2114[1] × days + r2114[0] × milliseconds
