Pre-verification
0 Preface
The K6CM is more effective when multiple parameters are set appropriately. This section covers the particularly important
settings.
Conduct the pre-verification as follows, and set the optimal parameters for the target equipment.
1. Specification of verification equipment
2. Recommended parameter settings during verification
3. Prior data collection and analysis
4. Collection of comparison data *
5. Threshold levels settings
* The absolute value of the threshold levels can be set for the K6CM-VB. See the User’s manual (N219) for more
information.
1 Specification of verification equipment
The K6CM is a product that quantifies the status of the motor and determines/discerns whether its status is Critical. There -
fore, it can evaluate the validity of a motor’s effectiveness through a comparison verification between a motor in a critical
state and a motor in a normal state.
One of the method for conducting a comparison verification is as follows.
(1) Measurements before and after maintenance
The maintenance engineer determines that the status is Critical and conducts measurements before and after the
maintenance (part replacement, overhaul, etc.) planned for the motor.
(2) Reproduction of critical state
Reproduce the critical state you want to detect in the target equipment and compare the normal state to the critical
state.
(3) Measurement of old and new equipment
Some equipment operate under the same conditions. If the equipment has been operating for a different number of
years, it is possible to conduct a new and old comparison. However, if the old equipment is not clearly in a critical
state, the difference may not be detectable.
Comparison before and after routine inspection
Changes before and after conducting routine tasks such as cleaning, greasing, and tightening installation bolts may
be too slight for the K6CM to detect. Note that there may be no change in the numerical value.
Overhaul
The K6CM-CI2M can detect abnormalities in the motor installation state. For this reason, if the motor is reinstalled
with the motor and load revolution axle misaligned, the K6CM-C12M will detect the misalignment of the revolution
axis as an error and the measured value may become larger. To perform correct verification, and to use the motor
longer in the normal state, we recommend aligning the motor and revolution axis when reinstalling.
