 When the inverter is ready to operate, the output of the operation
ready signal (RY) is ON. It is also ON during inverter running.
 When the output frequency of the inverter rises to or above
Pr. 13 Starting frequency, the output of the inverter running
signal (RUN) is turned ON. During an inverter stop or DC
injection brake operation, the output is OFF.
 The output of the RUN3 signal is ON when the inverter
running and start signals are ON.
(For the RUN3 signal, output is ON if the starting command is
ON even when a fault occurs or the MRS signal is ON.

When using the RY, RUN and RUN3 signals, assign functions to
Pr. 190 to Pr. 196 (output terminal selection function) referring to the
table below.

 If the inverter comes to trip, the ALM and ALM2
signals are output.
 The ALM2 signal remains ON during a reset
period after fault occurrence.
 When using the ALM2 signal, set "94 (positive
Time
logic)" or "194 (negative logic)" to any of Pr. 190 to
Pr. 196 (output terminal function selection) to assign
the function to the output terminal.
 The ALM signal is assigned to the A1B1C1
contact in the initial setting.
