Illustration 107: Stages of Condition-based Monitoring
• Baseline Computation: During the initial stage, baselines for different types of condition-based monitoring are computed,
based on the type of baseline mode selected.
•
Threshold Calculation: Once the baseline is computed, the thresholds for warnings (stage 1 and stage 2) and alarm/fault are
computed based on the warning or alarm/fault mode. The threshold and mode are set via parameters.
• Monitoring: After the thresholds are calculated, condition-based monitoring begins. Alarm/fault and warnings are triggered
during deviations to notify customers.
To begin condition-based monitoring, a baseline must be generated. During this activity, the system captures motor stator winding
speed points for each baseline. Define the duration, minimum and maximum speed for baseline generation. During baseline gener-
ation, 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, 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 cre-
ated for baseline measurement. The duration for baseline calculation can be specified. Baseline measurements can copy to oth-
er drive or return to same drive after factory reset.
• Manual Run: The measurement points can be manually configured directly through modified parameters. Manual run can be
made before or after baseline run.
11.24.2 (ID 3501) BaselineRun Start
Location in the menu: P3.24.2.1
Use this parameter to activate baseline run.
Baseline run is made before normal operation. Idea is to compare actual measurements with measurements taken when the system
was in healthy/normal condition. The measurements from healthy condition are called "baseline".
In baseline run, the measurements of the motor current unbalance for stator winding, vibration, and motor torque are collected.
