8.2 System runtime

8.2 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
If r2114[0] has reached a value of 86,400,000 ms (24 hours), r2114[0] is set to the value 0 and
the value of r2114[1] is increased by 1.
Parameter
r2114[0]
r2114[1]
You cannot reset the system runtime.
