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. System Configuration Basic Configuration *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. For the most recent information on models that have been certified for safety standards, refer to your OMRON website.

Note: Warning: Indicates that it is time for maintenance. Critical: Indicates that it is time for replacement. *1. Trigger modes other than external trigger Always: Trigger is not used. Measurement/m onitoring are performed continuously after the power of the K6CM unit is turned on. Internal trigger: Measurement/monitoring starts based on the rela tion 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. Name Meaning 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 self- diagnosis 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. “Ci1 ”: Degradation level 1, “Ci2”: Degradation level2, “A”: Current Front operation part [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. Others If two keys are simultaneously pressed and held for 5 seconds or longer, all settings of the main unit are reset to facto ry defaults. Main unit status display 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) Transistor output 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 OFF = Comprehensive alarm: Warning or Normal / ON = Comprehensive alarm: Critical 17-18 Self-diagnosis error output. OFF: A self-diagnosis error has occurred ON: Other than the above External trigger input 3-4 Input of the external contact signal to control measurement timing. You can use "Trigger Type" to specify whether measurement/monitoring continue for a set time after starting by the rise or fall of the external contact, or are executed while the external contact is ON.

Comprehensive Current Diagnosis Type Technical Data (Reference) Use one CT per motor to detect current flowing into the motor. Select a CT that matches the motor capacity. Note: At no load, the motor current is at approximately half rated load. Select a CT that can cover the range of 50% to 100% of rated current. Use the following expression when calculating the current value from the motor capacitance. (Example) When a 5.5-kW motor is used at 200 V 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.

Vibration & Temperature Type: Technical Data 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.

Note: Warning: Indicates that it is time for maintenance. Critical: Indicates that it is time for replacement. *1. Can be used only with EIP CPU version 1.2 or higher. *2. Trigger modes other than external trigger Always: Trigger is not used. Measurement/monitoring are perform ed continuously after the power of the K6CM unit is turned on. Internal trigger: Measurement/monitoring st arts 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. Name Meaning 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 self- diagnosis 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. “MΩ”: Insulation resistance, “mA”: Leakage current Front operation part [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 Others If two keys are simultaneously pressed and held for 5 seconds or longer, all settings of the main unit are reset to factory defaults. Main unit status display 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) Transistor output 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 OFF = Comprehensive alarm: Warning or Normal / ON = Comprehensive alarm: Critical 17-18 Self-diagnosis error output. OFF: A self-diagnosis error has occurred ON: Other than the above External trigger input 3-4 Input of the external contact signal to control measurement timing. You can use "Trigger Type" to specify whether measurement/monitoring continue for a set time after starting by the rise or fall of the external contact, or are executed while the external contact is ON. You can also specify settings to enable selection of a trigger mode other than external trigger. *2

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. and the length of wire between ZCT (IRT) and the motor [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. Part name Manufacturer Model Rubber holder Midori Anzen Co. Ltd.
