Maintenance timer alarm

The maintenance timer output signal (Y95) is output when the inverter's cumulative energization time reaches the time
period set with the parameter. MT1, MT2 or MT3 is displayed on the operation panel.
This can be used as a guideline for the maintenance time of peripheral devices.

Operation example of the maintenance timer 1 (Pr.503, Pr.504) (with both MT2 and MT3 OFF)
• The cumulative energization time of the inverter is stored in the EEPROM every hour and displayed in Pr.503 (Pr.686,
Pr.688) in 100 h increments. Pr.503 (Pr.686, Pr.688) is clamped at 9998 (999800 h).
• When the value in Pr.503 (Pr.686, Pr.688) reaches the time (100 h increments) set in Pr.504 (Pr.687, Pr.689), Maintenance
timer signal (Y95) is output, and also
• For the terminal used for Y95 signal output, assign the function by setting "95 (positive logic)" or "195 (negative logic)" in
any of Pr.190 to Pr.196 (output terminal function selection).
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".
• MT is displayed on the FR-PU07 parameter unit if any of MT1, MT2 or MT3 is activated.
• 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.

Description
Displays the inverter's cumulative
energization time in increments of 100 h
(read-only).
Writing the setting of "0" clears the
cumulative energization time while
Pr.503 = "1 to 9998". (Writing is disabled
when Pr.503 = "0".)
Set the time until the maintenance timer
signal (Y95) is output.
MT1 is displayed on the operation panel.
