(5) Cooling fan life display
The cooling fan speed of 50% or less is detected and "FN" is displayed on the operation panel and parameter unit (FR-
PU07). As an alarm display,
Pr. 255
bit2 is turned on and also an alarm is output to the Y90 signal.
4.20.3 Maintenance timer alarm (Pr.503, Pr.504)
The cumulative energization time of the drive unit is stored into the EEPROM every hour and is displayed in
Pr.503
Maintenance timer
in 100h increments.
Pr.503
is clamped at 9998 (999800h).
When the
Pr.503
value reaches the time set to
Pr.504 Maintenance timer alarm output set time
(100h increments), the
maintenance timer alarm output signal (Y95) is output.
For the terminal used for the Y95 signal output, assign the function by setting "95" (positive logic) or "195" (negative logic)
to any of
Pr.190 to Pr.192 (output terminal function selection)
.
NOTE
For replacement of each part, contact the nearest Mitsubishi FA center.
When the cumulative energization time of the drive unit reaches the parameter set time, the maintenance timer output
signal (Y95) is output.
(MT) is displayed on the operation panel.
This can be used as a guideline for the maintenance time of peripheral devices.

0 (1 to 9998)
Displays the cumulative energization time
of the drive unit in 100h increments.
(Reading only)
When
Pr. 503
= "1 to 9998", writing the
setting value of "0" clears the cumulative
energization time.
(Writing is disabled when
Pr. 503
= "0".)
504
Maintenance timer alarm
output set time
9999
0 to 9998
Time taken until when the maintenance
timer alarm output signal (Y95) is output.
9999
No function
The above parameters can be set when
Pr.160 Extended function display selection
= "0".
NOTE
The cumulative energization time is counted every hour. The energization time of less than 1h is not counted.
Changing the terminal assignment using
Pr.190 to Pr.192 (output terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
