Life display of the cooling fan
• If a cooling fan speed of less than the specified speed (refer below) is detected, Fan alarm (FN) is displayed on the
operation panel and the parameter unit. As an alarm display, Pr.255 bit 2 is turned ON and also a warning is output to the
Y90 signal and Alarm (LF) signal.
• For the terminal used for the LF signal, set "98" (positive logic) or "198" (negative logic) in any of Pr.190 to Pr.196 (output
terminal function selection).
NOTE
• When the inverter is mounted with two ore more cooling fans, "FN" is displayed with one or more fans with speed of 50% or
less.
• 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.
• For replacement of each part, contact the nearest Mitsubishi FA center.
Life display of internal air circulation fans (IP55 compatible models)
• IP55 compatible models are equipped with the internal air circulation fan inside the inverter other than the cooling fan. The
internal fan fault (FN2) appears on the operation panel (FR-DU08) when the rotations per minute is less than 70%
of the rated value for the internal air circulation fan. (FN is displayed on the parameter unit (FR-PU07).) As an alarm display,
Pr.255 bit 4 is turned ON and also a warning is output to the Y90 signal and Alarm (LF) signal.
• For the terminal used for the LF signal, set "98" (positive logic) or "198" (negative logic) in any of Pr.190 to Pr.196 (output
terminal function selection).
NOTE
• 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.
• For replacement of each part, contact the nearest Mitsubishi FA center.
