Mitsubishi Electric 800 Series Instruction Manual page 37

• The Life alarm (Y90) signal turns ON when either the control circuit capacitor life, main circuit capacitor life, cooling fan life,
inrush current limit circuit life, internal air circulation fan life or the estimated residual life of the main circuit capacitor reaches
the level set to output the life alarm.
• For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of Pr.190 to Pr.196 (Output
terminal function selection).
NOTE
• When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE), the life alarm for the Control circuit capacitor
life (Y86 signal), Main circuit capacitor life (Y87 signal), Cooling fan life (Y88 signal), Inrush current limit circuit life
(Y89 signal), and the estimated residual-life of the Main circuit capacitor (Y248 signal) can be output individually.
• 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.

Stroke limit signals
• The Upper stroke limit (LSP) signal and the Lower stroke limit (LSN) signal can be used in any operation mode other than the
SSCNET III(/H) operation mode.
• To assign the LSP and LSN signals to input terminals, set "88 (LSP)" and "89 (LSN)" in any two parameters from Pr.178 to
Pr.189 (Input terminal function selection).
• When the LSP and LSN signals are not assigned to any input terminal during position control by the FR-A8AL pulse train input
or position control by pulse train input to the inverter (Pr.419 Position command source selection ="1 or 2"), the STF and
STR signals are used as the Upper stroke limit and the Lower stroke limit signal.
• The rotation direction indicators on the LCD operation panel (FR-LU08) and the parameter unit (FR-PU07) differ depending on
the ON/OFF state of the stroke limit signals as shown in the table below. Note that "---" is displayed regardless of the ON/OFF
state of the stroke limit signals in the SSCNET III(/H) operation mode.

Reset selection after inverter faults are cleared (Pr.349,
N241)
• When the communication option is specified for the command source in Network operation mode, it is possible to select
whether the inverter is reset after the "Fault reset" command is executed. (Only when the HMS network option is installed.)
