NOTE
• The Y95 signal turns ON when any of MT1, MT2 or MT3 is activated. It does not turn OFF unless all of MT1, MT2 and MT3
are cleared.
• If all of MT1, MT2 and MT3 are activated, they are displayed in the priority of "MT1 > MT2 > MT3".
• The cumulative energization time is counted every hour. Energization time of less than 1 h is not counted.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

5.4.18 Current average value monitor signal
The output current average value during constant-speed operation and the maintenance timer value are output to the Current
average monitor (Y93) signal as a pulse. The output pulse width can be used in a device such as the I/O unit of a programmable
controller as a guideline for the maintenance time for mechanical wear, belt stretching, or deterioration of devices with age.
The pulse is repeatedly output during constant-speed operation in cycles of 20 s to the Current average monitor (Y93) signal.
