Maintenance timer alarm
The Maintenance timer (Y95) signal is output when the inverter's cumulative energization time reaches the time period set with
the parameter. "MT" is displayed on the operation panel. This can be used as a guideline for the maintenance time of peripheral
devices.
• The cumulative energization time of the inverter is stored in the EEPROM every hour and displayed in
Pr.503
in 100 h
increments. The number indication on
Pr.503
stopped at 9998 (999,800 hours).
• When the value in
Pr.503
reaches the time (100 h increments) set in
Pr.504
, the Maintenance timer (Y95) signal is output,
and also "MT" is displayed on the operation panel.
• For the terminal used for the Y95 signal output, assign the function by setting "95" (positive logic) or "195" (negative logic)
in any parameter from
Pr.190 to Pr.196 (Output terminal function selection)
.
NOTE
• 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.

Maintenance timer
0
0 (1 to 9998)
Displays the inverter's cumulative energization time in
increments of 100 hours (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".)
