Life Display Of The Cooling Fan; Life Display Of Internal Air Circulation Fans - Mitsubishi FR-A800 Instruction Manual

Life display of the cooling fan
• If a cooling fan speed of less than the specified speed (refer below) is detected, Fan alarm
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.
