Measurement
trigger signal
Dedicated tool
By keeping a PC or PLC continuously connected, you can monitor the state of a motor.
Note. Even without a PC, the alarm bar of the main unit notifies you of changes of motor state.
*1. For details, refer to the technical data on DataSheet (N218).
*2. Measurement may not be possible depending on the drive frequency of the inverter. See the User's Manual (N219) for
more information.
*3. Can be used only with EIP CPU version 1.2 or higher.

Measurement
trigger signal
Dedicated tool
By keeping a PC or PLC continuously connected, you can monitor the state of a motor.
Note1. Even without a PC, the alarm bar of the main unit notifies you of changes of motor state.
Note2. When an inverter is used with three-phase, four-conductor, N-phase ground, correct measurement is not possible.
*1. For details, refer to the technical data on DataSheet (N218).
*2. Can be used only with EIP CPU version 1.2 or higher.
