Runtime (operating hours counter)
Total system runtime
The total system runtime is displayed in p2114 (Control Unit). Index 0 indicates the system
runtime in milliseconds after reaching 86.400.000 ms (24 hours), the value is reset. Index 1
indicates the system runtime in days.
The value is saved when the system is switched off.
Once the drive unit has been switched on, the counter continues to run with the value that
was saved the last time the drive was switched off.
Relative system runtime
The relative system runtime since the last POWER ON is displayed in p0969 (Control Unit).
The value is in milliseconds and the counter is reset to 0 after 49 days.
Actual motor operating hours
The motor operating hours counter p0650 (drive) resumes when the pulses are enabled.
When the pulse enable is withdrawn, the counter is stopped and the value saved.
To store the value, you need a CU320 with order number 6SL3040-....-0AA1 and version C
or higher.
The counter is deactivated with p0651 = 0.
If the maintenance interval set in p0651 is reached, fault F01590 is triggered. Once the
motor has been maintained, the maintenance interval must be reset.
Operating hours counter for the fan
The operating hours of the fan in the power unit are displayed in p0251 (drive).
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has
been replaced).
The service life of the fan is entered in p0252 (drive).
Alarm A30042 is output 500 hours before this figure is reached.
Monitoring is deactivated with p0252 = 0.
