The followings are common to the K6CM.

(1) Use the power supply voltage, input power, and other power supplies and transformers with suit-

able capacities and rated outputs.

(2) When cleaning the product, do not use thinners or solvents. Use commercial alcohol. (3) Confirm that wire does not stick up after wiring of stranded cable. (4) In case of passage wiring, install these by 10 A per 1 terminal because when products are con-

nected more than one in parallel, quite many electric currents to be called off.

(5) The terminal block may be damaged if specialized tool is not used. Use a recommended flat-blade

screwdriver to inserted into a release hole on the terminal block.

(6) Do not apply excessive force to bend or pull the communications cables, and do not place heavy

objects on the cables. Doing so will damage the cables.

(7) Refer to the status information of the product on the data link communications and refer to the

received data only in case of no errors occur with the product.

The followings are for K6CM-VB and K6CM-VBS1 sensors.

(8) Wipe off the dirt on the mounting surface and screw mounting with 17 mm nominal size of wrench.

• Recommended mounting screw tightening torque: 4.4 to 5.4 N•m

• Mounting hole dimension: M6 holes (depth: 9 mm min.)

(9) The easy-positioning magnet is for the purpose of seeking the detected position. In the case of

using the product permanently, be sure to use it after it is mounted by screws.

(10) In the case of vertical mounting or reverse mounting with the easy positioning magnet, be careful

of the sensor falling.

(11) Refer to Installation of the Vibration Sensor Head on page 5-7 to install the sensor correctly. It may

be impossible to detect high frequency vibration.

(12) Do not disassemble the sensor. It may not operate correctly. (13) Be careful of incorrect wiring or short circuit for wiring. (14) Do not use the preamplifier connected to the other products. (15) If there is a vibration reduction device such as dampers and rubbers between the vibration mea-

surement object and the sensor, it is difficult to detect the vibration and it will not be able to measure it correctly, so do not install as much as possible.

(16) In the case of insertion and removal of connector, be sure to do it by holding the connector with

hands.

(17) Do not remove the connector with holding the cable. (18) Check the direction of the key groove before you use the connector. (19) Do not wire with wet hands. It may result in operation failure or product damage when power is

being supplied to the product.

(20) When fitting the connector, be sure to do it with hands, not to use tools. It may result in damages if

the tool like plier is used.

(21) In the case of removal of the fitness of the connector between the sensor and the preamplifier, be

careful to do it not to adhere water or dirt on the fitting surface. It may result in faulty contact at the connector.

(22) Install cables to avoid any force is applied to the connector. In case the any force is applied to the

connector, it causes that the performance of protection structure becomes incapable.

(23) Do not use the connector as a scaffold or put heavy objects on it. It may result in connector dam-

age.

K6CM Motor Condition Monitoring Device User’s Manual (N219)

Precautions for Correct Use

(24) Do not mount the way that the force is directly applied to the fitting part of the connector or the root

part of the cable connection. It may result in connector damage or cable disconnection. (25) When bending cables, use cables with a minimum bending radius of 25 mm. (26) Use preamplifier after it is fixed on the DIN rail or with screws. In case of using unfixed one, it is in

the condition that force is easily applied to the cable, and the cable may be broken. (27) About oil-resistance of sensor head/cable; (Not tested by UL)

Follow the procedure below in case of using the product under the condition that uses cutting oil

since the life expectancy and the performance of the product are affected.

• Use the product in the specified condition for cutting oil

• Use the product at the dilution rate of cutting oil that is recommended by the cutting oil makers.

• Do not use the product in oil or water.

There are cases that the influence on the life expectancy of the product differs depending on the type of the use oil. Make sure in advance that there is no deterioration of the sealing material by the cutting oil, before using the product.

(28) Do not use the alarm output function for control. This function can be used only to detect abnormal

conditions and to output the alarm. (29) Avoid using the product in places near a radio, a television set, or a wireless device.

The product may result in radio disturbance for these devices.

The followings are only for K6CM-IS.

(30) Do not clamp directly to the lines exceeding 480 VAC. UL certification complies with 480 VAC. (31) Use the special ZCT (IRT) after fixing it with screws. If used without fixing, a load is easily applied

on the cable, and the cable may become disconnected. (32) ZCT (IRT) is an special product. Do not use it for any other purposes. Otherwise, failure may occur. (33) When clamping wires with special ZCT (IRT), do it in a right direction. If clamped in the wrong

direction, correct measurement cannot be taken. (34) The distorted ratio of the input waveform should be 30% or less. If it is used in a circuit with large

distortion of waveform, it may cause unnecessary operation. (35) Do not use in a circuit with the waveform is distorted. The error will increase due to the influence of

the distorted waveform.

The followings are only for K6CM-CI2.

(36) Make sure that the rating of the used special CT and the special CT setting of the product agree. (37) Do not ground the special CT. Doing so may cause instability when measuring failure. (38) Do not clamp directly to the lines exceeding 600 VAC. UL certification complies with 480 VAC. (39) Place the cable between the special CT and the product at a distance of 6 mm or more from other

1-1-1 What is the K6CM Motor Condition Monitoring Devices For?

K6CM Motor Condition Monitoring Device is a device that visualizes and monitors the state of the motor by measuring the feature quantity of the three-phase induction motor. Motors other than three-phase induction motors (e.g., synchronous motor, single phase motor, servo motor, stepping motor) are excluded. Depending on the feature quantity to be measured, you can select from the following three types.

Type Outline Feature quantity measured

Comprehensive current diagnosis type

K6CM-CIM K6CM-CI2M

Vibration & temperature type

K6CM-VBM

Insulation resistance type

K6CM-ISM

*1. Two degradation levels, degradation level 1 and degradation level 2, are measured by using different algo-

rithms. The K6CM-CIM measures only degradation level 1, so it is referred to as the degradation level in the software tool.

Measures the current waveform of a motor and the current waveform of an inverter driving motor and monitors the distortion of the current waveforms as the degradation levels.

Monitors motor bearing abnormalities from the vibration and temperature.

Monitors the motor insulation resistance.

Measures the degradation levels*1 and current of the motor.

Measures the motor vibration (acceleration and velocity) and motor temperature.

Measures the insulation resistance.

By properly using these three types as necessary, you can catch the state of the induction motor and decide the appropriate maintenance time.

1-2 Features

1-2-1 Features Common for All Models

• Multiple K6CM devices can be connected to one PLC or one PC, and multiple motor statuses can be monitored at one time.

• Status monitoring can be confirmed on site easily from the alarm bar display and numeric LCD display on the front of the K6CM device.

• Two levels of warning failure and critical failure are prepared as alarm monitoring levels. Two outputs of the transistor are possible when the alarm occurs.

• A self-diagnosis function and replacement timing notification are incorporated. With these functions, errors of the K6CM device and when to be replaced can be determined.

• Trigger functions using an external input or internal set value comparison enable monitoring only when specified conditions such as startup of the motor are met. In addition, the maximum and minimum values can be automatically calculated and output during the period that those conditions are met. (*1)

• EtherNet/IP (i.e., tag data link, CIP message communications) is supported. Measurement values and internal data can be read, and alarm setpoints and other set values can be written from the PLC or PC. (*2)

*1. For the insulation resistance type K6CM device, the trigger function using the external input can be supported

for the Eip cpu version 1.10 or higher.

*2. Tag data link can be read only. Write not possible.

1-2 Features

1-2-1 Features Common for All Models

Features of Main CPU Version 1.2 or Later

• Measurement is possible in a stable state even after starting up the motor using the trigger function following a monitoring delay time.

• Modbus TCP is supported. Measurement values and internal data can be read, and alarm setpoints and other set values can be written from the PLC or PC by using message communications.

• The indication for the unit of measurement value (monitoring type) on the K6CM device numeric LCD display can be switched automatically at a 5-second interval. This allows you to confirm status monitoring without touching the operation keys of the K6CM device.

1 Overview

1-2-2 Overview and Features of the Comprehensive Current Diagnosis

Type

Overview

The current waveform of the motor is a smooth sine wave if the motor and load are in the normal ideal states. If the motor or load are abnormal, noise appears in the current waveform as shown below.

(1) Motor and load are normal.

Cross-sectional view of the motor

The current is a smooth "sine wave".

Smooth rotation

(2) An abnormality is occurring.

Cross-sectional view of the motor

Abnormal vibration

Abnormality affecting degradation level Major factors

Misalignment Coupling abnormal, centering shortage, etc. Load imbalance Unbalance of rotating objects such as fans Rotor abnormality Breakage inside the motor Cavitation, air contamination Vacuum bubbles in water stream, pipe internal pressure drop, etc. Overload Excessive rotational load

Note The degradation level may appear differently depending on the failure condition of the motor or load, or

depending on the installation condition.

"Noise" may come up in the current.

Features

• A motor error can be detected by representing the degree of deviation of the current waveform between a normal motor and an abnormal motor in numerical values (as degradation level 1).

• A motor error can be detected by analyzing the frequency components affecting the rotating shaft of the motor and representing them in numerical values. It is suitable for monitoring of inverter drive (as degradation level 2).

• Degradation levels 1 and 2 can be monitored simultaneously. (The K6CM-CIM can only monitor degradation level 1.)

• The K6CM can also detect motor peripheral malfunctions affecting the rotating shaft of the motor.

K6CM Motor Condition Monitoring Device User’s Manual (N219)

 Mechanism of degradation level 1

Frequency components of abnormality

1 Overview

For degradation level 1, the K6CM device compares the current waveform of the motor with the smooth sine wave of the ideal state, and represents the degree of deviation from the smooth sine wave in numerical values. If the motor or load is abnormal, that degree of deviation will be large, and the value of degradation level 1 will be large.

Motor and load are normal Motor and load are abnormal

Equivalent to smooth sine wave Deviated from smooth sine wave

If the current waveform of the motor contains many noise components such as with inverter driving, the value of degradation level 1 will be large because there will be deviation from the ideal state even if the motor and load are normal. Therefore, the difference between the normal state and abnormal state will be small.

1-2 Features

1-2-2 Overview and Features of the Comprehensive Current Diagnosis Type

 Mechanism of degradation level 2

For degradation level 2, the K6CM device determines what percentages of the frequency components affecting the rotating shaft of the motor were included in the drive frequency components when frequency analysis was performed on the current waveform of the motor, and represents them in numerical values. If the motor or load is abnormal, the frequency components affecting the rotating shaft of the motor will be large, and the value of degradation level 2 will be large.

Since the frequency components affecting the rotating shaft of the motor are clearly captured and represented as numerical values, even in environment with many noise components such as inverter driving, a motor or load abnormality is captured with excellent sensitivity and the variations in the numerical values tend to be also small compared with degradation level 1. Therefore, it is suitable for monitoring an inverter-driven three-phase induction motor.

1-2-3 Features of Vibration & Temperature Type

• Simultaneous monitoring of motor vibration (i.e., acceleration and velocity) and motor temperature are possible.

• Mainly bearing wears can be detected by the acceleration.

• Mainly load imbalance and misalignment can be detected by the velocity.

• The acceleration and velocity alarm threshold values of K6CM-VBM vibration & temperature type can be set automatically with the software tool (software tool version 1.3.0.0 or later).

1-2-4 Features of Insulation Resistance Type

• Insulation resistance can be monitored.

• Resistance leakage current (I0r) can be measured. (*1)

• Capacitive leakage current (I0c) can also be measured. (*2)

*1. Alarm output cannot be performed.

*2. Can be read via EtherNet/IP or Modbus TCP. Unit display and alarm output cannot be performed.

1-2-5 Features of Software Tool

Using a K6CM-CIM

• When the motor is driven by an inverter, it may not be possible to monitor the motor or load abnormalities. Refer to 3-4-1 Comprehensive Current Diagnosis Type (K6CM-CI2) on page 3-19 in 3-4 Guide for Setting Alarm on page 3-19 for details.

Using a K6CM-CI2M

• In an environment where the motor is driven by an inverter, if the degradation level 1 is used as the measurement value, it may not be possible to monitor the motor or load abnormalities. Therefore, it is recommended to use the degradation level 2. Refer to 3-4-1 Com-

prehensive Current Diagnosis Type (K6CM-CI2) on page 3-19 in 3-4 Guide for Setting Alarm on page 3-19 for details.

• Since the frequency band of the harmonics of the drive frequency and the frequency band in which errors such as load imbalance and misalignment appear are the same frequency band for a 2-pole meter, sensitivity may be reduced with degradation level 2.

Note When you use an inverter to drive the motor, you may not be able to check the degradation tendency of

the motor. However, under the following conditions, changes in acceleration are more likely to be confirmed.

• When the inverter driving frequency is 50 Hz or more and the frequency is stable

• When the carrier frequency of the inverter is 12.5 kHz or more and the frequency is stable

Use an inverter after trying according to your installation environment.

connection, take safety measures such as fixing the cables.

)

Secure the attachment which is sold separately to the exterior of the motor using adhesive. Screw the vibration sensor head into the fixed attachment.

We recommend method 1 with high absolute accuracy, but if you cannot tap off the motor, use method

An easy-mounting magnet (called "Sensor Easy mounting magnet") is included. It can be used to determine the position to be measured. Note that measurement accuracy is not guaranteed in the case of magnet mounting.

3-1-1 Measuring and monitoring by K6CM

What is Measuring?

After the power is turned ON, K6CM calculates measurement values every sampling period based on the input from the sensor.

The calculation of the measurement value is executed inside the K6CM even before the trigger start, and the measurement display is updated when the trigger is established.

This is called measuring.

What is Monitoring?

According to the trigger setting, K6CM performs threshold value judgment of the Warning/Critical level for a measurement value, and then determines whether the measurement value is within the Warning/Critical level as an "individual alarm". Next, the OR logic is obtained for each "individual alarm" and Normal/Warning/Critical is judged for each monitor target as the "Comprehensive alarm".

This is called monitoring. It displays the front LCD alarm bar of the K6CM device and performs transistor output.

As shown in the figure, it is as follows.

3-2-2 Moving average

The moving average is the process of assuming the average value of past n times of measurement value which includes the measurement value of that time to be a current measurement value each time the sampling of the measurement value is performed. The moving average makes it possible to suppress the instantaneous fluctuation of the measurement value and make the tendency of the measurement value easier to see. The image of moving average is shown below.

3-2-3 Monitoring Delay

The monitoring delay is a function to delay the start of monitoring, and is used to wait for the measurement values to stabilize. The monitoring delay operates when the trigger mode is the external trigger or the internal trigger, and monitoring starts once the monitoring delay time has elapsed after the trigger start.

Trigger is a function of updating and monitoring the measurement values when certain conditions are met. To observe the aging of the motor, it is necessary to set the installation state, load, and rotation speed of the motor during measurement to the same condition, and to measure the motor rotating at a constant speed avoiding the state where the motor is stopped or accelerating or decelerating. Depending on the application, select the trigger mode from Free run (while power is ON), External Trigger, or Internal Trigger. The operation of each trigger mode is shown in the table below.

3 Measuring and monitoring System

Monitoring Delay Settings

To observe the aging of the motor, it is necessary to set the condition of the motor at measurement to the same condition, and to measure the motor in a stable state avoiding the state where the motor is stopped or accelerating or decelerating. Start measurement at the appropriate timing by setting the monitoring delay time in reference to the following.

1 Determination of trigger mode

Refer to 3-2-4 Trigger Mode on page 3-5 and decide the trigger mode and trigger type according to the application.

2 Determination of moving average times

Reducing the moving average times can help capture instantaneous fluctuations.

Increasing the moving average times can suppress the steep fluctuation of measurement values and capture the overall trend.

Determine the moving average times of measurement values according to the state of measurement value.

3 Determination of monitoring delay time (when trigger mode is external trigger or internal trigger)

To obtain the measurement value when the state of the motor is stable, set the monitoring delay time using the following calculation formula.

In the example in the figure above, when the time to wait for motor to stabilize is 10 seconds and the measurement value is the velocity of vibration & temperature type (sampling period: 0.5 seconds), the value for the monitoring delay time will be the following value.

Monitoring delay time

= time to wait for motor to stabilize + sampling period × (moving average times + 1) = 10 s + 0.5 s x (2+1) = 11.5 s

Also, determine a monitoring time that will fit within the motor stable operation.

3-2-5 Maximum Value and Minimum Value of Measurement value

The K6CM retains the Max./min. measurement value during measuring and monitoring period as internal data. They can be read by the software tool or by message communications.

With this function, by reading the maximum or minimum value of the measurement value for a certain period and comparing it with another period, it is possible to detect signs of Criticality of the motor.

Also, changing the setting allows you to set the display value of the front LCD of the K6CM device to the maximum value or the minimum value.

The software tool or message communications can be used to reset the retained Max./min. values after monitoring by operating the "Max./min. reset" setting.

The measuring and monitoring period depends on the trigger mode. The maximum value and the minimum value also operate according to each trigger mode as follows.

3-3-3 Relationship Between Alarm and Display/Output

The relationship between the state of comprehensive alarm (Warning, Critical), alarm bar, numeric LCD display, and transistor output 1, 2 is shown below.

Described below is the case where the alarm latch is disabled and the case where it is enabled.

When the Alarm Latch is Disabled

If you set the alarm latch to "Disable (no latch)" using the software tool or message communications, the alarm condition of the comprehensive alarm (warning or critical) will not be latched.

After the comprehensive alarm (Warning or Critical) occurs, if the measurement value falls below the hysteresis (i.e., 10% of the threshold setting value) of the Warning or Critical threshold (for the upper limit alarm) or higher (for the lower limit alarm), the state of the comprehensive alarm (alarm bar and transistor outputs 1 and 2) is canceled.

Example of actual measurement: Initially measurement value of the degradation level 1 is “51”.

Example: The degradation level 1 measured at the begging of

3-4 Guide for Setting Alarm

3-4-1 Comprehensive Current Diagnosis Type (K6CM-CI2)

Refer to the following guideline to set the alarm threshold value of the monitored degradation level in the comprehensive current diagnosis type (K6CM-CI2).

Monitoring by Degradation Level 1

 When driving the motor by direct connection to commercial power supply

When driving the motor without an inverter, use the following setting values at first.

• Degradation level 1 alarm threshold value (Warning): 20

• Degradation level 1 alarm threshold value (Critical): 50

Note The default value of alarm threshold (Warning) is set to 30, which is the above 20 plus 10.

Since the value of degradation level 1 differs depending on the equipment status and motor driving conditions, set alarm threshold values suitable for the equipment using the above alarm threshold values as a guide.

Refer to the K6CM Motor Condition Monitoring Device STARTUP GUIDE (N221-E1) for details.

3-4 Guide for Setting Alarm

3-4-1 Comprehensive Current Diagnosis Type (K6CM-CI2)

 When driving the motor with an inverter

With an inverter, the influence of the inverter control appears in the current waveform. The degradation level 1 will be measured to be larger than the actual value.

Therefore, shift the above initial setting value in the degradation level 1 measured in a new product or the normal condition after overhauling before use.

Use the following setting values at first.

3 Measuring and monitoring System

Degradation level 2 alarm threshold value (Warning): 20

Degradation level 2 alarm threshold value (Critical): 50

Since the value of degradation level 2 differs depending on the equipment status and motor driving conditions, set alarm threshold values suitable for the equipment using the above alarm threshold values as a guide.

Refer to the K6CM Motor Condition Monitoring Device STARTUP GUIDE (N221-E1) for details.

 When driving the motor with an inverter

Degradation level 2 clearly captures not only the noise caused by inverter driving but also other factors such as the frequency components affecting the rotating shaft of the motor, and represents them as numerical values. Since a motor or load abnormality is captured with excellent sensitivity and the variations in the numerical values are also small compared with degradation level 1, degradation level 2 is suited to monitoring an inverter-driven three-phase induction motor.

Choose whether to use degradation level 1 or degradation level 2 depending on the equipment to be monitored.

tion level

Degradation level 1

Description

ties for which certain frequency components increase because certain frequency components among the frequency components affecting the rotating shaft of the motor are clearly captured and represented as numerical values.

Degradation level 1 represents the degree of deviation between the whole current waveform obtained during the sampling period and the smooth sine wave of the ideal state as numerical values. Therefore, this is suited for monitoring abnormalities that have an irregular effect on the shaft of the motor.

Choose whether to use degradation level 1 or degradation level 2 based on the trends of the measured data because the degradation level appears differently depending on the failure condition of the motor or load or depending on the installation conditions.

Degradation level 1 and degradation level 2 are both measured at the same time. Therefore, you can also monitor using both of them or just one of them depending on the abnormality you wish to monitor.

When measuring a 2-pole motor with degradation level 2

Since the frequency band of the harmonics of the drive frequency and the frequency band in which errors such as load imbalance and misalignment appear are the same frequency band for a 2-pole motor, sensitivity may be reduced with degradation level 2. If that happens, monitor it using degradation level 1.

If you want to monitor using only degradation level 1 or degradation level 2

If you want to monitor using only degradation level 1, set the alarm threshold of degradation level 2 to the maximum value (9999) so that the alarm of degradation level 2 is not output. Likewise, if you want to monitor using only degradation level 2, set the alarm threshold of degradation level 1 to the maximum value.

3-4-2 Vibration & Temperature Type (K6CM-VB)

For the Vibration & temperature type (K6CM-VB), the threshold setting method differs depending on the monitored object (i.e., acceleration, velocity) as follows.

Monitoring by Acceleration

In acceleration monitoring, you can generally monitor the bearing wears.

There are two threshold setting methods in accordance with the state of the motor.

 Monitoring by relative value

Monitor by relative value is used when it can be determined that there is no abnormality in the motor (new or overhauled).

Set the alarm threshold value referring to the table below based on the initial value that is set after installation.

Alarm Criteria

Warning 3 to 5 times the initial value after installation Critical More than 5 times the initial value after installation

3-4 Guide for Setting Alarm

3-4-2 Vibration & Temperature Type (K6CM-VB)

 Monitoring by absolute value

Monitor by absolute value is used when the motor status is unknown.

The threshold guide value is determined from the shaft diameter D [mm] of the motor to be monitored and the rotation speed N [rpm].

Refer to the figure below and set the alarm threshold.

The default value of the alarm threshold is set as follows.

• Alarm threshold (Warning): 0.5 G

• Alarm threshold (Critical): 1.0 G

When the motor capacity is set to 11 kW, the shaft diameter is 42 mm, and when the 4 pole motors are directly put in the power supply (60 Hz), the rotation number is 1800 rpm. 42 mm × 1800 rpm =

7.56 × 10

Monitoring by Velocity

In monitoring on monitoring, you can generally monitor the load imbalance, misalignment etc.

Set the alarm threshold from the class (i.e., capacity and installation status) of the motor to be monitored. Refer to the figure below and set the threshold value. (It will be set according to ISO 2372.)

The target motor class follows the table below.

Equipment class Definition

I Small-sized machines (typical example: motor with output less than 15 kW) II Medium-sized machine (typical example: motor with output of 15 kW to 75 kW or less

and machine with 300 kW or less) III Large-sized machines: machine installed on a heavy foundation with high rigidity. IV Large-sized machines: machine installed on a foundation with soft rigidity.

The default value of the alarm threshold is set as follows.

• Alarm threshold (Warning): 40 mm / s

• Alarm threshold (Critical): 45 mm / s

Velocity reacts not only to vibrations but also to things like shocks. An alarm may be output due to unnecessary vibration or shock when mounting a vibration and temperature sensor. Therefore, the default value of the alarm threshold is set to a higher value. In actual use, set the alarm threshold to an appropriate value according to the monitor target.

If you want to monitor using only acceleration or speed

If you only want to monitor using acceleration, set the alarm threshold of speed to the maximum value (9999) so that the speed alarm is not output. Likewise, if you only want to monitor using speed, set the alarm threshold of acceleration to the maximum value.

Works

An electrolytic capacitor is built in the K6CM device. From the manufacturing point of time, the electrolytic solution permeates through the sealing rubber and the evaporation of the electrolyte in the electrolytic solution progresses with time. As a result, deterioration of characteristics such as decrease in capacitance occurs. Due to that, the K6CM device can not exhibit sufficient performance over time.

The replacement timing announcement function indicates a guideline period until the K6CM device is unable to achieve sufficient performance due to the deterioration of electrolytic capacitor characteristics. Also, when reaching the guideline value, K6CM device front display and communications status will change. You can use this function as a guideline to know when to replace the K6CM device.

Note The replacement timing announcement indicates a guideline that the K6CM device cannot achieve suffi-

cient performance due to deterioration of the electrolytic capacitor. The guideline does not include failures caused by other factors.
