*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 fault output 2 signal (ALM2) turns OFF as soon as the power supply switches OFF.
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".
⋅ When Pr. 76 Fault 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 fault occurs, the signal output is switched to the fault code output.)
⋅ The output assignment of the terminal RUN and fault output relay are as set above regardless of Pr. 76.
CAUTION
⋅ Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
⋅ Do not assign signals which repeat frequent ON/OFF to terminal ABC1, terminal ABC2. Otherwise, the life of the relay contact
decreases.

*1 This signal turns OFF during power failure or undervoltage.

REMARKS
⋅ RUN signal is assigned to the terminal RUN in the initial setting.
⋅ During IPM motor control, the RUN signal is output about 100ms after turning ON the start command (STF, STR). The delay is
due to the magnetic pole detection.

⋅ 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 inverter's output frequency reaches Pr. 13 Starting
frequency or higher (0.01Hz under IPM motor control), the
inverter running signal (RUN) is output. 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
