PARAMETERS
(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 330 for the fault description.)
