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 communication 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 (IP67G) 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.
The followings are for K6CM-IS and K6CM-CI.
(28) Error will be large if the product is used for thyristor control.
(29) Do not use the alarm output function for control. This function can be used only to detect abnormal
conditions and to output the alarm.
(30) 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.
(31) Make sure that the rating of the used CT and the CT setting of the product agree.
(32) Do not ground the specified CT. Doing so may cause instability when measuring failure.
(33) Do not clamp directly to the lines exceeding 600 VAC.
(34) Use 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.
The followings are only for K6CM-IS.
(35) ZCT (IRT) is an special product. Do not use it for any other purposes. Otherwise, failure may occur.
(36) When clamping wires with ZCT (IRT), do it in a right direction. If clamped in the wrong direction,
correct measurement cannot be taken.
(37) 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.
(38) Do not use in a circuit with the waveform is distorted. The error will increase due to the influence of
the distorted waveform.

1-1 Overview and Features
This section describes an overview and features of the K6CM.
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. Depending on the feature quantity to be measured, you can select from the following three types.
• Vibration & temperature type: Measure vibration (acceleration, velocity) and motor temperature
• Insulation resistance type: Measuring insulation resistance
• Comprehensive current diagnosis type: Measures the degradation level and current
By properly using these three types as necessary, you can catch the state of the induction motor and
decide the appropriate maintenance time.
Features
• Software tool "Motor condition monitoring Tool" that is provided with the K6CM device enables immediate setup and status monitoring.
• With the built-in EtherNet/IP, this K6CM device can also be monitored by PLCs.
• Confirmation of the K6CM device front display makes monitoring on site easy.
• Alarm output threshold (Caution, Critical) can be set for each measured value.
• Trigger function enables measurement at required timing.
• Errors of the K6CM device itself and when to be replaced can also be detected.

1-1-2 Features
z K6CM Common Functions
• 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.
• Trigger functions using an external input (*1) or internal set value comparison enable measuring
and monitoring only when specified conditions such as startup of the motor are met.
• The software tool enables initial settings of the K6CMs and alarm monitoring of measurement values. It also enables reading of measurement values at specified intervals and automatic data storage (with the CSV format).
• The K6CM device supports the EtherNet/IP network and can be monitored remotely with it.
• Multiple K6CM devices can be connected to one PLC or one PC, and multiple motor statuses can
be monitored at one time.
• Measurement value and internal data can be read, and alarm setting values and other setting values can be written (*2) with the PLC and PC via EtherNet/IP (i.e., tag data link, CIP message
communications).
*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.

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.

Also, there is no designation in the phase to be installed. Be careful of the installation direction stated on the
CT label and mount it to any one phase.
Note The level of degradation may vary when the motor is driven by the inverter. In that case, slightly shift the
inverter drive frequency.
Also always measure and monitor the level of degradation at the same inverter drive frequency.
Mount a dedicated CT between the motor and the inverter.
