*1 Note that when the frequency setting is varied using an analog signal or
frequency) signal may alternate on and off depending on that varying speed and the timing of the varying speed due to acceleration/
deceleration time setting. (The output will not alternate on and off when the acceleration/deceleration time setting is "0s".)
*2 When a power supply reset is performed, the alarm output 2 signal (ALM2) turns off as soon as the power supply switches off.
*3 The alarm output 2 signal "ALM2" can not be assigned to the extended assignment terminal of the option unit (FR-A7AY, FR-A7AR).
REMARKS
⋅ The same function may be set to more than one terminal.
⋅ When the function is executed, the terminal conducts at the setting of any of "0" to "99", and does not conduct at the setting of
any of "100" to "199".
⋅ The signal will not function if a value other than the above is set to any of Pr. 190 to Pr. 196.
⋅ When Pr. 76 Alarm code output selection = "1", the output signals of the terminals SU, IPF, OL and FU are switched as set in Pr.
76. (When an inverter alarm occurs, the signal output is switched to the alarm output.)
⋅ The output assignment of the terminal RUN and alarm output relay are as set above regardless of Pr. 76.
CAUTION
⋅ When terminal assignment is changed using Pr. 190 to Pr. 196 (output terminal function selection), the other functions may be
affected. Please make setting after confirming the function of each terminal.
⋅ Do not assign signals which repeat frequent ON/OFF to A1, B1, C1, A2, B2, C2. Otherwise, the life of the relay contact decreases.

Function
Output when the inverter's protective
function is activated to stop the output
(major fault). Continue outputting the signal
Alarm output 2
during inverter reset and stop outputting
after reset is cancelled.
Maintenance timer Output when Pr. 503 rises to or above the Pr.
signal 504 setting.
Output to the terminal when a value is set to
Remote output
the parameter.
Output when a minor fault (fan failure or
Minor fault output
communication error warning) occurs.
Output when the inverter's protective function is
Alarm output activated to stop the output (major fault). The
signal output is stopped when a reset turns on.

⋅ 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 the inverter protective function is activated or
the MRS signal is on.
⋅ When using the RY and RUN3 signals, assign functions to Pr.
190 to Pr. 196 (output terminal selection function) referring to the
table below.
