When the inverter is running and has output frequency(can be zero),
the terminal becomes ON.
When the inverter stops due to a fault, the terminal becomes ON.
Refer to the descriptions of F4.19,F4.20.
When the output frequency and set frequency error is less than F4.21
(percentage of the maximum frequency with respect to) the set value,
the output ON.
If the inverter runs with the output frequency of 0, the terminal
becomes ON. If the inverter is in the stop state,the terminal becomes
OFF.
The inverter judges whether the motor load exceeds the overload
pre-warning threshold before performing the protection action. If the
pre-warning threshold is exceeded,the terminal becomes ON. For
motor overload parameters,see the descriptions of F9.00~F9.02。
The terminal becomes ON 10s before the inverter overload
protection action is performed.
The terminal becomes ON when the count value reaches the value
set in Fb.08
The terminal becomes ON when the count value reaches the value
set in group Fb
The terminal becomes ON when the detected actual length exceeds
the value set in Fb.05
When simple PLC completes one cycle, the terminal outputs a pulse
signal with width of 250 ms.
If the accumulative running time of the inverter exceeds the time set
in F4.17, the terminal becomes ON
If the set frequency exceeds the frequency upper limit or lower limit
and the output frequency of the inverter reaches the upper limit or
lower limit, the terminal becomes ON.
In speed control mode, if the output torque reaches the torque limit,
the inverter enters the stall protection state and meanwhile the
terminal becomes ON.
If the inverter main circuit and control circuit become stable, and the
inverter detects no fault and is ready for RUN, the terminal becomes
ON.
When the input of AI1 is larger than tAI2, the terminal ON.
If the running frequency reaches the upper limit, the terminal
becomes ON.
If the running frequency reaches the lower limit, the terminal
becomes ON. In the stop state, the terminal becomes OFF.
Refer to the communication protocol.
If the output frequency of the inverter is 0, the terminal becomes ON.
In the state of stop, the signal is still ON.
If the inverter accumulative power-on time (F8.13)exceeds the value
set in F4.16, the terminal becomes ON.
