■
Inverter running –
RUN
(Function code data = 0)
This output signal is used to tell the external equipment whether the inverter is running. Turning the
inverter main circuit (output gate) ON or OFF switches the
RUN
signal ON or OFF, respectively.
This signal is also OFF when the motor is being tuned.
If this signal is assigned in negative logic (Active OFF), it can be used as a signal indicating
"inverter being stopped."
■
Speed arrival –
FAR
(Function code data = 1)
This output signal comes ON when the difference between the detected speed and reference speed
(pre-ramp) comes within the allowable error zone (specified by E30).
When the inverter’s run command is OFF, this output signal also comes OFF.
For details, refer to the description of function code E30 (Speed Arrival).
■
Speed detected –
FDT
(Function code data = 2)
Speed detected –
FDT2
(Function code data = 31)
These output signals FDT or FDT2 come ON when the detected speed exceeds the speed detection
level specified by E31 or E36 respectively, and it goes OFF when the detected speed drops below the
"Detection level (E31 or E36) - Hysteresis band width (E32)”. These output signals are not affected
by the run command.
For details, refer to the description of function codes E31, E36 and E32 (Speed Detection).
■
Undervoltage detected –
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.
■
Inverter ready to run
–
RDY
(Function code data = 10)
This output signal comes ON when the inverter becomes ready to run by satisfying all of the
following conditions.
- Terminal [EN
1]/[EN2]
ON
-
BX
OFF
- No alarm detected
- DC link bus voltage higher than the specified undervoltage level
- Initialization of options completed
Note that the activation of a
BATRY
command always turns the
RDY
signal OFF.
■
MC control
–
SW52-2
(Function code data = 12)
This output signal is used for MC control.
For details, refer to the descriptions of function codes L85 and L86 (MC Control).
■
Cooling fan in operation –
FAN
(Function code data = 25)
This output signal is ON when the cooling fan is in operation, and OFF when it is stopped. This
signal can be used to make the cooling system of peripheral equipment interlocked for an ON/OFF
control.
