REMARKS
⋅ Run signal is assigned to the terminal RUN in the initial setting.
(3) Fault output signal (ALM, ALM2 signal)
Inverter fault occurrence

Fault output signal(ALM)
Fault output 2 signal(ALM2)
Reset signal(RES)
REMARKS
Refer to page 274 for the inverter fault description.
(4) Input MC shutoff signal (Y91 signal)
⋅ The Y91 signal is output at occurrence of a fault attributable to the failure of the inverter circuit or a fault caused by
a wiring mistake.
⋅ When using 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 indicates the faults that will output the Y91 signal. (Refer to page 274 for the fault description.)
