*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.
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.

Turned on and off alternately every time the
Power saving power saving average value is updated
average value when the power saving monitor is used.
updated timing Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Average current value and maintenance
Current average timer value are output as pulses.
value monitor signal Cannot be set to Pr. 195 and Pr. 196 (relay
output terminal).
Output when the fault occurs. Continues

Operation
of the operation panel (FR-DU07), the output of the SU (up to
⋅ 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.
