Function assignment of external
terminal and control
(4) Input MC shutoff signal (Y91 signal)
⋅ The Y91 signal is output at occurrence of an alarm attributable to the failure of the inverter circuit or an alarm
caused by a wiring mistake.
⋅ When using the Y91 signal, set "91 (positive logic)" or "191 (negative logic)" to any of Pr. 190 to Pr. 196 (output
terminal function selection) to assign the function to the output terminal.
⋅ The following table indicates the alarms that will output the Y91 signal. (Refer to page 236 for the alarm description.)
