(M) Monitor display and monitor output signal Parameters
5 - 240
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 page 6-9.)
5.8.7 Output frequency detection
The inverter output frequency is detected and output as output signals.
