Function assignment of external terminals
Alarm output signal (ALM, ALM2)
If the inverter comes to an alarm stop, the ALM and ALM2 signals are output. (Refer to
section 7.1 for the alarm description.)
The ALM2 signal remains on during a reset period after alarm occurrence. When using the
ALM2 signal, set "94" (source logic) or "194" (sink logic) to any of Pr. 190 to Pr. 196 "Output ter-
minal function selection" to assign the function to the output terminal.
The ALM signal is assigned to the A1, B1 and C1 contacts in the initial setting.

Alarm output 2 signal (ALM2)
Fig. 6-135: Alarm signals
Input MC shutoff signal (Y91)
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 (source logic)" or
"191 (sink logic)" to any of Pr. 190 to Pr. 196 "Output terminal function selection" to assign the
function to the output terminal.
