Models of K6CM Device

The monitor types of K6CM device are as follows.

*1. Measuring the magnitude of vibration of things are displacement, velocity, and acceleration. Displacement in-
dicates how far it moved. The velocity shows how fast it moves, and the acceleration shows how fast it has
reached that velocity. In the K6CM-VBM, velocity and acceleration can be measured.
*2. The motor temperature is measured with the sensor head, and the room temperature is measured by the tem-
perature sensor inside the pre-amplifier.
*3. The insulation resistance value measured by the insulation resistance type may be different from the measure-
ment value with the insulation resistance meter.
*4. Leakage current includes Ior and Ioc. The relationship between Ioc and Ior is shown below.
Ioc
With the K6CM-ISM, only Ior (resistance leakage current) can be measured (alarm monitoring can not be per-
formed). There is no indication on the front of the K6CM device for Ioc (leakage current due to capacitance).
It can be read out with Motor condition monitoring Tool or EtherNet/IP.
*5. The K6CM-CIM measures the degree of normality/fault of the motor from the motor current waveform. The low-
er the degradation level, the better the motor is in the normal condition.
