Any negative logic (Active OFF) command cannot be assigned to the functions marked with ""in the
"Active OFF" column.
■ Inverter running -- RUN (Function code data = 0)
Inverter output on --
RUN2 (Function code data = 35)
These output signals tell the external equipment that the inverter is running at a starting frequency or higher.
If assigned in negative logic (Active OFF), these signals can be used to tell the "Inverter being stopped" state.
Output signal Basic function Remarks
RUN
Goes OFF even during DC braking or
dew condensation prevention.
RUN2
These signals come ON when the inverter is running.
Under V/f control:
These signals come ON if the inverter output frequency
exceeds the starting frequency, and go OFF if it drops
below the stop frequency. The
RUN signal can also be
used as a "Speed valid" signal
DNZS.
Comes ON even during DC braking,
pre-exciting, zero speed control, or
dew condensation prevention.
Under vector control, both RUN and RUN2 come ON when zero speed control or servo-lock function is enabled.
Undervoltage detected (Inverter stopped) -- LU (Function code data = 3)
This output signal comes ON when the DC link bus voltage of the inverter drops below the specified undervoltage level,
and it goes OFF when the voltage exceeds the level.
This signal is ON also when the undervoltage protective function is activated so that the motor is in an abnormal stop
state (e.g., tripped).
When this signal is ON, a run command is disabled if given.
Torque polarity detected -- B/D (Function code data = 4)
The inverter issues the driving or braking polarity signal to this digital output judging from the internally calculated
torque or torque command. This signal goes OFF when the detected torque is a driving one, and it goes ON when it is a
braking one.
