To begin condition-based monitoring a baseline must be generated. During this activity, the
system captures motor stator winding speed points for each baseline. The user can define
the duration, minimum and maximum speed for baseline generation. During baseline
generation, 10 speed points are captured. The first and last speed point is captured based
on the defined minimum and maximum speed respectively.
When speed points are not captured properly, baseline generation fails, then a new baseline
has to be generated.
The baseline serves as a reference for threshold limits. Using parameters, the user can
select the type of baseline measurement.
•
Baseline Run: The drive controls the motor speed and monitors required values to derive
a baseline. The drive creates a speed profile for baseline measurement. The drive interrupts
the application during baseline run to operate on the speed profile created for baseline
measurement. The duration for baseline calculation can be specified. Baseline
measurements can copy to other drive or return to same drive after factory reset.
•
Manual Run:
“Manual” means that the measurement points can be directly configure
d
manually by the user through modified parameters. Manual run can be made before or after
baseline run.
