Operation
7.15 Runtime (operating hours counter)
SINAMICS DCP
360 Operating Instructions, 09/2019, A5E34382853K
For p55102 = 4, the following applies:
Fault F60067 is already initiated at the start of the derating (75 °C), and the device is shut
down.
Alarm A60080 is already output at 70 °C.
Both thresholds can be reduced using p55101[1].
Overvoltage range
For a 30 kW device, the following applies: The voltage limits are reduced by 12 % per 1000
m at installation altitudes above 2000 m.
This derating is applied to parameter r55600[2 ... 5]; however, it does not influence the value
of this parameter itself.
Therefore, the derating influences the current and power limits, see Chapter "Current
limitation and power limitation (Page 336)", fault F60500 is output at the corresponding lower
voltages.
The 120 kW device does not have this restriction.
7.15 Runtime (operating hours counter)
Total system runtime
The total system runtime is displayed in r2114 (Control Unit).
● Index 0 = system runtime in ms.
After reaching 86400000 ms (24 h), the value is reset.
● Index 1 = system runtime in days.
The counter value is saved when the power is switched off. After the drive unit is powered
up, the counter continues to run with the most recently saved value.
Note
Faults and alarms are stamped with this system runtime.
