Motor stopped due to slow flowrate under PID control -- PID-STP

(Function code data = 44)
This output signal is ON when the inverter is stopped due to the slow flowrate stop function
under PID control.)
 Refer to J149 through J160 and J249 through J260.
Low output torque detected -- U-TL (Function code data = 45)

This output signal comes ON when the torque value calculated by the inverter or torque
command drops below the level specified by E80 (Low torque detection (Level)) for the
period specified by E81 (Low torque detection (Timer)). The minimum ON-duration is 100
ms.
 Refer to E80 and E81.
Running forward -- FRUN (Function code data = 52)

Running reverse -- RRUN (Function code data = 53)
Output signal Assigned data
FRUN
RRUN
In remote operation -- RMT (Function code data = 54)

This output signal comes ON when the inverter switches from local to remote mode.
 For details of switching between remote and local modes, refer to Chapter 5, Section
5.5.4 "Remote and local modes."
Run command entered -- AX2 (Function code data = 55)

This output signal comes ON the moment the inverter is ready to run after receipt of a run
command.
 Refer to E01 through E07, Function code data = 38.
Motor overheat detected by thermistor -- THM (Function code data = 56)

Even when the PTC thermistor on the motor detects an overheat, the inverter turns this signal
ON and continues to run, without entering the alarm OH4 state. This feature applies only
when H26 data is set to "2."
 Refer to H26 and H27.
Terminal [C1] wire break -- C1OFF (Function code data = 59)

This output signal comes ON when the inverter detects that the input current to terminal [C1]
drops below 2 mA interpreting it as the terminal [C1] wire broken.
Maintenance timer -- MNT (Function code data = 84)

Once the inverter's cumulative run time or the startup times for the motor 1 exceeds the
previously specified count, this output signal comes ON.
 Refer to H44, H78 and H79.
Frequency arrival signal (with frequency detection)

-- FARFDT (Function code data = 87)
This output signal comes ON when both the FAR (Frequency arrival signal) and FDT
(Frequency detected) come ON. (The FARFDT is an AND condition signal of the FAR and
FDT.)
