Motor Condition Monitoring Device
K6CM-CI
Quantifying the status of a three-phase
induction motor.
• The “comprehensive current diagnosis” can monitor not only
for motor problems, but also abnormal load-side conditions.
• Simply install a CT on the control panel enables monitoring.
• The software tool (set-up and simple monitoring tool) is also
provided.
• K6CM-CI2M is suitable for use in an excessive noise
environment such as using an inverter. Supports Modbus TCP
in addition to EtherNet/IP.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.

Note : 1. Even without a computer, the alarm bar of the main unit notifies you of changes of motor state.
2. The degradation level may appear differently depending on the failure condition of the motor
or load, or depending on the installation condition.
*1. 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 the User's manual (N219) for
details.
*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 meter, sensitivity may be reduced with degradation level 2.
*3. The CT cable cannot be extended.

*1. Trigger modes other than external trigger
Always:
Trigger is not used. Measurement/monitoring are performed continuously after the power of the K6CM unit is turned on.
Internal trigger: Measurement/monitoring starts based on the relation between the measured value and set value (trigger level).
You can use "Trigger Type" to specify whether measurement/monitoring start and continue for a set time when the measured
value is over, or under, the set value (trigger level), or are executed while the measured value exceeds the set value (trigger
level).
Also, the external trigger function can be used only when the insulation resistance type is EIP CPU version 1.1 or higher.

Use the following expression when calculating the current value from the motor capacitance.
Motor capacitance (kW) × 1000
Current value of motor (A) =
Motor voltage (V) × √3 × Power factor (0.9) × Efficiency (0.8)
(Example) When a 5.5-kW motor is used at 200 V
Current value of motor =
5.5 × 1000
200 × √3 × 0.9 × 0.8
= 22 A
Therefore, the CT K6CM-CICB025 in which 22 A is within the measurement range is selected.
The measurement range is within 20 and 100 A even in the case of K6CM-CICB100, which means that 22 A is within the range and this model
can also be used. However, during selection, priority must be given to a CT having a small rated current value in order to realize more accurate
measurement.
Note: In the expression shown above, general values must be used for the power factor and efficiency, and the load factor must be 100%. However,
depending on the actual operating environment, the actual current value and measured value may be different. If the CT is used at a current value
that is below the lower-limit value of the measurement range of the CT, the measurement error of the degradation level will increase. Therefore, if
possible, measure the current during a steady-state operation with a clamp meter, etc., and select a CT corresponding to the current value.

Alarm bar
A bar on which the color of the emitted
light changes according to the alarm
status.
It is indicated in the following colors during measurement/monitoring.
Green: Alarm status (normal)
Yellow: Alarm status (Warning)
Red: Alarm status (Critical)
The alarm bar is lit out in each of the following states:
When the power is OFF, when measurement is not being performed, and when a selfdiagnosis error has occurred, etc.
Measurement type
Indicates the type of the measured value
being displayed. The type can be
switched each time the [DISP] key is
pressed on the front operation part.
“G”: Acceleration, “mm/s”: Velocity, “T”; Motor temperature,
“ T”: Temperature Gap (difference between motor temperature and room
temperature)
[ALM RST] key
Releases the latched alarm state.
The main use of this key is to release the latched and fixed alarm state after returning
from the fault state to the normal state.
[DISP] key
Switches the type of the measured value being displayed.
You can switch between display-fixed mode and display auto switching mode by long-pressing for 3 seconds. *1

part
The status of the main unit is indicated by
lighting of the LCD characters.
“MON”: Measurement / monitoring is being performed
“ERR”: A self-diagnosis error has occurred
“AGE”: Running Time notification (it is recommended to replace the product main unit)
13-14
Output of the alarm status (Warning).
Can be set to Normally Closed or
Normally Open.
When measurement/monitoring is in progress,
and the output method is Normally Closed
ON = Comprehensive alarm: Normal / OFF = Comprehensive alarm: Warning or Critical
and the output method is Normally Open
OFF = Comprehensive alarm: Normal / ON = Comprehensive alarm: Warning or Critical
15-16
Output of the alarm status (Critical).
Can be set to Normally Closed or
Normally Open.
When measurement/monitoring is in progress,
and the output method is Normally Closed
ON = Comprehensive alarm: Warning or Normal / OFF = Comprehensive alarm: Critical
and the output method is Normally Open

*2. Trigger modes other than external trigger
Always:
Trigger is not used. Measurement/monitoring are performed continuously after the power of the K6CM unit is turned on.
Internal trigger: Measurement/monitoring starts based on the relation between the measured value and set value (trigger level).
You can use "Trigger Type" to specify whether measurement/monitoring start and continue for a set time when the measured
value is over, or under, the set value (trigger level), or are executed while the measured value exceeds the set value (trigger
level).
Also, the external trigger function can be used only when the insulation resistance type is EIP CPU version 1.1 or higher.

Pairing of sensor head and pre-amplifier
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. The sensor head cannot be replaced.
To verify the combination, check the serial numbers on the label of the sensor head and the label of the pre-amplifier. The same serial number
means the correct combination.
If you change the combination of factory shipping conditions and then use them, the value of acceleration and the value of velocity will be
inconsistent, so measurement cannot be correctly monitored.

Insulation Resistance Type Technical Data (Reference)
Method of measuring the value on the insulation resistance meter
Leakage current includes two types, namely capacitive leakage current (Ioc) that flows through the earth capacity, and resistive leakage current
(Ior) that flows due to the degradation of wiring and devices, and is the cause of electric shock and fire. The leakage current is determined by
detecting the value of the zero-phase current Io, which is the combined component of Ioc and Ior. (See the figure below)

About changes in the measurement accuracy
If there is almost no insulation deterioration in the motor, almost the entire constituent of Io becomes Ioc, and the measurement accuracy of Ior
declines. Further, if the Ioc based on the motor-specific electrical capacitance is larger than Ior, then the measurement accuracy will similarly
decline. Particularly, if the electrical capacitance increases in proportion to the capacitance of the motor, the measurement accuracy changes
depending on the motor capacitance.
The following items are the possible parameters affecting the measurement accuracy.
Increase in Ioc ......................Type of motor (manufacturer, structure), capacitance, number of poles,
and the length of wire between ZCT (IRT) and the motor
Other noise components.......Through-current, through-position
External factors.....................Voltage imbalance

[Effect of residual current]
Another noise component is the residual current* (hereinafter, specified as Ir). Ir increases in proportion to the through-current.
* Residual current
Residual current refers to the error that occurs as a result of an imbalance in the magnetic flux of each phase inside the core due to the
arrangement of the through-wire of ZCT.
Errors also occur as a result of the imbalance in the magnetic circuit of ZCT.
Ir combines with Io, and is output to the secondary side of ZCT. Ir is the same frequency component as Ior, and the amount of current or the phase
difference with respect to Ior changes depending on the through-position of the power line passing through ZCT. Therefore, isolation from Ior, which
must essentially be detected, becomes difficult.
If the position of ZCT and the through-wire is fixed once, the phase of Ir does not change. Moreover, by fixing the through-wire in the center of
ZCT, Ir can be reduced. Fix and install the through-wire in the center as much as possible.
Use the following holder to fix the through-wire in the center of ZCT.
