2.2.3 Enabling Condition-based Monitoring Features
In this recommendation, the scenario considered is to enable condition-based monitoring, when one sensor is installed on the
drive.
Procedure
1.
Go to Parameter Group 45 -** Condition-based Monitoring.
2.
Set the values to raise warnings for condition-based monitoring features, as described in the table.
N O T I C E
Make sure to congureparameter 45-00 Function inorder to generate [1] Warnings or [2] Warnings & Alarms, for proper
functioning of condition-based monitoring features.
The recommendation is to set [1] Warnings in parameter 45-00 Function. Setting [2] Warnings & Alarms in the param-
-
eter can cause the AC drive to trip, as alarms stops the drive.
2.3 Overview on Condition-based Monitoring
Condition-based monitoring in Danfoss VLT® drives enables to regularly check the condition and performance of the machine when
the drive is in service, and detects potential mechanical, motor, or application failures before the occurrence of an actual failure.
Benets of installing the condition-based monitoring rmware are as follows:
•
Reduces unexpected downtime
•
Eliminates unexpected halts in production
•
Optimizes maintenance
•
Reduction of spare part stock inventory
•
Optimizes production processes
Condition-based monitoring functions
Following are the 3 functions introduced in Condition-based monitoring. All the functions can be enabled at the same time for
monitoring the drive.
•
Motor stator winding monitoring: For this type of monitoring capability, an additional equipment is not required. The motor
current signature (inter-turn short circuit or unbalance in motor winding) is detected in drive. Damages caused by motor stator
winding isolation occurs over a period of time. When more winding turns are impacted, the overcurrent protection is activated
due to extensive heating and stops the motor
•
Load envelope: For this type of monitoring capability, an additional equipment is not required. Mechanical load of an application is monitored by comparing current load curve with expected load curve based on data gathered during commissioning.
During monitoring, overload and under-load deviations, which occur in applications, are detected.
•
Vibration monitoring: For this type of monitoring capability, the installation of vibration sensor(s) is required. Speed related
vibration (RMS) monitoring via external vibration sensor, detecting early signs of motor misalignments.
monitoring
N O T I C E
ISO10816 standard provides guidance for evaluating vibration severity for machines operating within 10–200 Hz of frequency
range. The standard shall be complied with before commissioning of vibration monitoring function.
2.4 Condition-based Monitoring Workow
Before starting the commissioning of condition-based monitoring, make sure that the system is congured (installed and commissioned) for normal operation of the drive.
Depending on the user's requirement, commissioning condition-based monitoring allows the possibility to congure thresholds before or after initiating the baseline measurement. The process of obtaining baseline measurements after initiation takes upto 6
months.
The following illustration depicts the two ways to commission condition-based monitoring in a drive.
Baseline conguration is the 1st step and essential when commissioning a drive for condition-based monitoring. A baseline signature is required to determine any deterioration in the stator winding, load operating point, or vibration level of the application. The
baseline is recorded for each of the activated condition-based monitoring functions.
Following are the dierent ways to congure baseline:
•
Baseline Run: The drive takes control of the motor speed and creates a certain congurable speed prole and measures the
relevant signals. Depending on the load conditions, it is not always possible to execute the baseline run when the load does not
allow.
•
Online Baseline: In this method, the baseline is created by the drive without interrupting the operation of the drive and application. For the user-specied period of time, the relevant signals are gathered by the drive. This method provides a better representation of normal variation in the application.
•
Manual Baseline: In this method, the baseline values are manually congured into the drive.This method is relevant when the
baseline values are dened using prior experience and the values are congured in the drive.
As illustrated in the graph below, a baseline consists of 20 speed points which are captured based on the user-dened minimum
and maximum observation interval.
For new installations, ISO 20816 recommends a wear-in period before taking a baseline measurement.
2.4.2 Step 2: Sensor Conguration (Optional)
Vibration monitoring requires installation of an external vibration transmitter. The sensor is connected via analog input using for
example terminal 53 or terminal 54. When using these terminals make sure to scale correctly. For AI53 S201 to ON = mA and for AI54
switch S202 to ON = mA.
Make sure to congure the correct scaling using parameters in Parameter Group 6-1* Analog Input 1.
For example when terminal AI53 is used, congure the following:
If these terminals are in use for other equipment, it is possible to extend the analog input with extension options. For information on
extension options, see the Selection Guide.
2.4.3 Step 3: Threshold Calculation
Dening or setting the threshold values
In this step, the thresholds are dened. There are 3 methods of threshold calculation.
•
Absolute: This is the common method when the equipment values are already known. The threshold has a xed value irrespec-
tive of the measured baseline value. For example, when the operator knows the absolute limit for the equipment, an absolute
value is set for the alarm threshold. In case of vibration monitoring, the limit values described in standards such as ISO
10816/20816 can be used for the alarm threshold as an absolute value.
•
Oset: This method of setting threshold values requires understanding of the application and baseline values. The threshold
depends on the baseline value to which a user-denedoset is considered in the threshold conguration. Setting a very low or
high value leading to false positives is a risk when using this method. False settings can cause irresponsive monitoring, even in
the case of faults.
•
Factor: This method is easier to use when compared to oset, because it does not require in-depth application knowledge. The
threshold depends on the baseline value which is multiplied by a factor. For example, the threshold value may be 150% of the
baseline. Setting a very high threshold is a risk when using this method of threshold calculation.
2.4.4 Step 4: Alarms and Warnings
In condition-based monitoring, for each feature, the user can dene activation stages for warnings and alarms. The interpretation of
alarm and warning color codes are as follows:
Green: No alarms are indicated. Condition-based monitoring operations continue.
Yellow: First indication of warning-stage 1 alarm is visible. Stage 1 warning fault are also shown as Stage 1 Warning (S1). Notication
to users to plan for maintenance operations. In this stage, condition-based monitoring operations continue.
Orange: Clear indication of warning-stage 2 alarm is visible. Stage 2 warning fault are also shown as Stage 2 Warning (S2). Notica-
tion to users to act as soon as possible before the fault becomes critical.
Red: A critical alarm has occurred and condition-based monitoring operations has stopped.
3 Examples of Condition-based Monitoring Functions
3.1 Example 1: Motor Stator Winding Monitoring
The AC drive provides variable magnitude of voltage and frequency to the stator terminal of connected 3-phase induction motors.
During healthy conditions of the motor with good stator winding insulation between inter-turn, the electrical signature shows consistency on the measurement. The electrical signature repeats the baseline value for repeated measurement.
However, in case of weakened insulation or inter-turn short circuit condition, the electrical signatures deviate from its original baseline values. The function withstands false positive in case of AC mains unbalance.
Illustration 5: Example of Motor Stator Winding Monitoring
3.2 Example 2: Load Envelope
The function monitors torque and speed prole of the application which is measured during the baseline measurement. The threshold conguration works similar to the other functions. Condition-based monitoring can detect underload and overload situations.
Hence, there are 2 warning stages for high side (overload scenario) and 2 warning stages for underload scenario.
The standard ISO 10816/20816 is the recommendation for vibration monitoring. The advantage, VLT® condition-based monitoring
provides, is the speed reference to the vibration level instead of an absolute level. The absolute level can mislead in lower levels of
the speed reference.
This chapter describes the commissioning of condition-based monitoring from baseline creation to monitoring the system. Before
performing commissioning steps, the assumption is the drive is installed and the license code for condition-based monitoring is
activated in the drive.
Danfoss Drives recommends to use MCT-10 Condition-based monitoring plug-in for commissioning of condition-based monitoring.
It is also possible to perform the commissioning using LCP. The following sections in this chapter, contain the following:
•
Commissioning using MCT-10 condition-based monitoring plug-in
•

•
Threshold Conguration Guidelines
Based on your MCT-10 version and activated license code, the plug-in is shown below.
Illustration 8: Condition-based Monitoring Plugin
4.2 Commissioning using MCT-10 Condition-based Monitoring Plug-in
Perform the following steps to set up conditiion-based monitoring in the drive.
•
Ensure MCT-10 version 5.11 or later is installed.
•
Ensure the desktop or laptop is connected to a powered-on AC drive with activated license code.
Note: The red highlight in the gure correspond to Danfoss recommended selections, and the blue highlight in the gure corre-
spond to application values. These values can vary based on application.
Procedure: The following are recommended steps to set-up condition-based monitoring:
Select minimum and maximum speed range using the slider or specify values in the textboxes.
The recommendation is to congure a speed window which relates to motor limitations. The motor speed is congured in
Parameter 4-11 Motor Speed Low Limit [RPM] and Parameter 4-13 Motor Speed High Limit [RPM].
Commissioning of Condition-based
Monitoring
Note: For advanced baseline settings, the minimum speed can be set as 30% of nominal speed as failures in low speed
measurement ranges are dicult to detect.
3.
Specify duration to capture baseline in Durationeld.
It is recommended to specify atleast 1 Week or more in the Durationeld.
Some of the duration options and corresponding baseline run values are specied below:
4.
Specify the speed band in the Speed step band, %eld.
Note: Do not set speed band to 0%. 0% is for niche applications.
5.
Congure vibration sensor information in Sensor source and Sensor unitelds.
By default, no value is selected in the elds. If vibration sensors are not congured, press Next.
6.
Congure the minimum and maximum reference values in AI53 minimum input, AI53 maximum input, AI54 minimum input,
and AI54 maximum input. Press Next.
The recommended minimum and maximum values are 0 and 100 respectively, providing a reference from 0% to 100%.
Commissioning of Condition-based
Monitoring
Make sure to provide the correct scaling either 0-20 mA or 4-20 mA. See Sensor Conguration (Optional).
