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 newly added. This model is suitable for use in an excessive noise environment such as using an inverter. Supports Modbus TCP in addition to Ether Net/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.

Using a K6CM-CIM *1. When the motor is driven by an inverter, it may not be possible to monitor the motor or load abnormalities. Refer to the User's manual (N219) for details. *2. Modbus TCP is not supported. *4. The CT cable cannot be extended.

Using a K6CM-CI2M *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. *3. 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. *4. The CT cable cannot be extended.

Frequently Asked Questions

Can this device monitor for abnormal load conditions besides motor issues?

Yes, it performs a comprehensive current diagnosis that monitors not only for motor problems but also for abnormal load-side conditions.

What considerations are necessary when monitoring motors driven by an inverter?

For K6CM-CI2M in inverter environments, degradation level 2 is recommended over degradation level 1 to ensure accurate abnormality monitoring.

Are there restrictions on the Connection Transformer (CT) cable setup?

The Continuous Current Transformer (CT) cable cannot be extended. You must select a CT that sets the current within the applicable motor's measurement range.
