Features

 Comprehensive Measurement of Conditions such as Vibration & Tempera-
ture, Insulation, Degree of Degradation, Current of Induction Motors
• This makes it possible to measure overall conditions of induction motors, such as vibration & tem-
perature, insulation resistance, leakage current, degradation level by comprehensive current diag-
nosis, and current, which was difficult to realize so far.
• For vibration and temperature, dedicated sensors are available.
• The measurement value is displayed on the front of the device. Alarm monitoring results are dis-
played in the bar on the front of the K6CM device, and the device can output alarms with contacts.
 K6CM Common Functions
• Two levels of warning failure and critical failure are prepared as alarm monitoring levels. Two out-
puts of the transistor are possible when the alarm occurs.
• Trigger functions using an external input (*1) or internal set value comparison enable measuring
and monitoring only when specified conditions such as startup of the motor are met.
• The Motor condition monitoring Tool enables initial settings of the K6CMs and alarm monitoring of
measurement values. It also enables reading of measurement values at specified intervals and
automatic data storage (with the CSV format).
• Supports EtherNet/IP network. This allows monitoring of multiple motors.
• Measurement value and internal data can be read, and alarm setting values and other setting val-
ues can be written (*2) with the PLC and PC via EtherNet/IP (i.e., tag data link, CIP message
communications).
*1. Insulation resistance type can not be triggered by the external input.
*2. Tag data link can be read only. Write not possible.
 Vibration and Temperature Type
• Simultaneous measuring and monitoring of motor vibration (i.e., acceleration and velocity) and
motor temperature are possible.
 Insulation Resistance Type
• Insulation resistance can be measured and monitored.
• Resistance leakage current (Ior) can be measured (monitoring/alarm with the K6CM device is not
possible)
• Capacitive leakage current (Ioc) can also be measured (only with EtherNet/IP)
 Comprehensive current diagnosis Type
• Motor malfunction (called "degradation level") can be detected by measuring and monitoring the
current including harmonic components.
