8.3 System runtime
By evaluating the system runtime of the inverter, you can decide whether you must replace
components subject to wear such as fans, motors and gear units.
Principle of operation
The inverter starts the system runtime as soon as the inverter is supplied with power. The
system runtime stops when the inverter 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), the inverter sets r2114[0] the
value 0 and increases the value of r2114[1] by 1.
Using system runtime, you can track the chronological sequence of faults and alarms over
time. When a corresponding message is triggered, the inverter transfers the parameter
values r2114 to the corresponding parameters of the alarm or fault buffer.
