Fault Output Signals (Alm, Alm2); Input Mc Shutoff Signal (Y91) - Mitsubishi Electric FR-F800 Instruction Manual

• When using the RY, RUN and RUN3 signals, refer to the following and assign the functions by Pr.190 to Pr.196 (output
terminal function selection).

Input MC shutoff signal (Y91)
• The Fault output 3 (Y91) signal is output when a fault originating in the inverter circuit or a connection fault occurs.
• To use the Y91 signal, set "91 (positive logic) or 191 (negative logic)" in any of Pr.190 to Pr.196 (output terminal
function selection) to assign the function to the output terminal.
• The following table shows the faults that output the Y91 signal. (For the fault details, refer to

(M) Monitor display and monitor output signal
• The Fault (ALM, ALM2) signals are output when the inverter
protective function is activated.
• The ALM2 signal stays ON during the reset period after the fault
occurs.
• To use the ALM2 signal, set "94 (positive logic) or 194 (negative
logic)" in any of Pr.190 to Pr.196 (output terminal function
selection) to assign the function to the output terminal.
• The ALM signal is assigned to the A1B1C1 contacts in the initial
status.
