Motor Condition Monitoring Device

K6CM

Quantifying the status of a three-phase

induction motor and pump.

The alarm output threshold default is

set. You can customize the value

according to the site.

As for comprehensive current diagnosis,

the degradation can be detected

comprehensively by combining each

motor part and the load side.

The insulation resistance of the three-

phase induction motor and pump can

be measured with current flowing (the

secondary side leakage current of the

inverter can also be detected).

Features

• Since the condition of the motor can be displayed in numeric values on the LCD, the motor condition can be checked

without a dedicated tool.

• The alarm output settings can be made according to the device, with reference to the threshold value that has

already been set by default.

• Depending on the threshold value setting for alarm output, the condition of the motor can be displayed on an alarm

bar in three colors; Green (normal), Orange (warning), and Red (critical).

• Equipped with a transistor output that externally outputs the status of the motor and error states of the K6CM main

unit.

• Monitoring can be performed easily on the PC by EtherNet/IP communication and a dedicated tool.

• The numeric values of vibrations, temperature, insulation resistance, and current can be monitored by the same

dedicated tool.

• The trend of the motor condition can be monitored by a dedicated tool, and thus indications of a degradation can

be monitored.

• Clamp-type CT/ZCT that supports easy post installation. With a clamp-type CT/ZCT, the device can be installed

without changing or removing the existing wiring, which makes post-installation easy.

• Comes with the self-diagnosis function of the main unit internal circuit and analog sensing circuit.

• Push-in Plus Terminal Technology reduces wiring work (double-insertion holes for crossover wiring).

• UL listed for easy shipping to North America (ZCT (IRT) is UL recognized).

* ZCT (IRT) is compatible with UL Recognition

K6CM 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.
PAGE 17
K6CM Effect of voltage imbalance The ZCT (IRT) calculates the Ior from the phase difference between the measured Io and the voltage. If there is a voltage imbalance, the phase of each phase voltage will change, and an error will occur in the calculation of Ior. Use the measurement results of the case when the voltage imbalance ratio is within 3%.
