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.
10
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.

1-1-1What 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.
TypeOutlineFeature 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.

1-2Features
1-2-1Features 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.

1-2-1 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
1-2-2Overview 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.
MisalignmentCoupling abnormal, centering shortage, etc.
Load imbalanceUnbalance of rotating objects such as fans
Rotor abnormalityBreakage inside the motor
Cavitation, air contaminationVacuum bubbles in water stream, pipe internal pressure drop, etc.
OverloadExcessive 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 normalMotor and load are abnormal
Equivalent to smooth sine waveDeviated 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. The dedicated cable between the special CT and the K6CM device is 2.9 m long. It cannot be extended. Also,
there is no designation in the phase to be installed. Be careful of the installation direction stated on the CT
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.
K6CM Motor Condition Monitoring Device User’s Manual (N219)
*1. The dedicated cable between the sensor head and the pre-amplifier is 2.9 m long. It cannot be extended.The
sensor head and the pre-amplifier are calibrated and inspected as a set at the factory shipment. Be sure to
use them with the combination shipped. For details, refer to Installation of the Vibration Sensor Head on page
5-7.
*2. The dedicated attached cable between the pre-amplifier and the K6CM device is 1 m. It can be extended up
to a maximum length of 100 m. Refer to A-5 Individual Specifications of the Dedicated Sensor on page A-10
for recommended cables.
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.

This section describes the nomenclature and functions of the K6CM devices, the special CT, the vibration and temperature sensor, and the insulation resistance sensor.
• With trigger (external trigger or internal trigger), "- - - -" is displayed if monitoring is not
started yet. When the monitoring is completed, the measurement value just before the
end is retained and displayed. For details, refer to Transition of Numeric LCD Display
on page 2-8.
*1. The above LCD color is retained after monitoring.
*2. Switching display of present value (PV), minimum value, and maximum value can be set by changing "Display
value type" from the software tool. (It is not switchable by front operation.)
*3. When the vibration & temperature sensor or the insulation resistance sensor (special ZCT (IRT)) is not con-
nected,
"- - - -" is displayed and the "MS" flashes.
When the input range is over, 7 segments will flash with the maximum value of the input range.
*4. Setting the alarm latch to "L" will latch the alarm condition of comprehensive alarm (warning or critical) (alarm
bar, transistor outputs 1 and 2). Release this latched state.
If you press the [ALM RST] key during monitoring, it returns to the comprehensive alarm state at that point (both
the alarm bar and transistor outputs 1 and 2).
*5. Running Time is a function to inform you when to replace the K6CM device. It is calculated from the internal
temperature and the operation time of the device.
*6. "MON" always lights up when the trigger mode is "Free run" (no trigger). When there is a trigger, it lights up
during monitoring. It turns off after monitoring is not started yet, and after monitoring is completed (only when
using the trigger function).

Mount the vibration sensor head on the shaft side exterior of the induction motor.
There are two ways to mount the vibration sensor head to the motor.
MethodDescription
Method 1: Screw Mounting (recommended)At the top of the armor of the motor, cut the tap into which the M6
screw vertically enters, and screw the vibration sensor head into
it.
Method 2: Adhesive Mounting (
*1. K6CM will not conform to safety standards if attaching the vibration sensor with adhesive. In the case of dis-
connection, take safety measures such as fixing the cables.
*1
)
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
2.
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.
The shapes of the easy-mounting magnet and the adhesive attachment are as follows.
These two shapes are similar. Be careful not to handle them by mistake.

3-1-1Measuring 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.

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.

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.

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.
1Determination 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.
2Determination 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.
3Determination 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.

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.

3-3-3Relationship 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.
When the Trigger Mode Is "Free run (no trigger)"
When power is turned ON, measuring and monitoring are started.

Example of actual measurement:
Initially measurement value of the degradation level 1 is “51”.
Example: The degradation level 1 measured at the begging of
use is 51 due to the influence of inverter control.
However, it is not abnormal.
Set the initial measurement value to 71 (51 + 20) for
the degradation level 1 alarm threshold value
(warning) and set the initially measurement value to
101 (51 + 50) for the degradation level 1 threshold
value (critical), and then perform trend monitoring.
The sensitivity of the degradation level differs
depending on the equipment to be monitored, so
adjust the values of 20 and 50 according to the
equipment.
Inverter Operation: 100%
3-4Guide for Setting Alarm
3-4-1Comprehensive 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.

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.

Monitoring by Degradation Level 2
Inverter noise
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.

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.
*1
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.

3-4-2Vibration & 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.

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 =

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 classDefinition
ISmall-sized machines (typical example: motor with output less than 15 kW)
IIMedium-sized machine (typical example: motor with output of 15 kW to 75 kW or less
and machine with 300 kW or less)
IIILarge-sized machines: machine installed on a heavy foundation with high rigidity.
IVLarge-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.

Precautions for Correct Use
*1. Around 1 day for the monitoring cycle is recommended.
If you set the monitoring cycle short, the memory capacity of the PC may run short.
In that case, move the log file to another location and reopen the project.
Guideline number of days to move log files is as follows.
Days = 50 * Measurement interval [seconds] / Number of connected K6CMs
For example, if the monitoring cycle setting = 5 seconds, and the number of connected K6CM = 10, Move the
log file to another location every 25 days and reopen the project.
*2. In the software tool version 2.0.0 and earlier, the graph display period can be set by selecting the tabs (1 hour,
1 day, 3 months, 6 months, 1 year, 2 years, 5 years, 10 years, 20 years).
In the software tool version 1.2.0.0 and later, you can move the graph in the time axis direction using the graph
time axis movement.
