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.
At power-off the counter value is saved.
After the drive unit is powered-up, the counter continues to run with the value that was saved
the last time that the drive unit was powered-down.
Relative system runtime
The relative system runtime after the last POWER ON is displayed in p0969 (Control Unit).
The value is in milliseconds and the counter overflows after 49 days.
Actual motor operating hours
The motor operating hours counter p0650 (drive) is started when the pulses are enabled.
When the pulse enable is withdrawn, the counter is stopped and the value saved.
If p0651 is at 0, the counter is deactivated.
If the maintenance interval set in p0651 is reached, alarm A01590 is triggered. Once the
motor has been maintained, the maintenance interval must be reset.
CAUTION
If the motor data set is switched during the star/delta changeover without the motor being
changed, the two values in p0650 must be added to determine the correct number of motor
operating hours.
