Under PID control -- PID-CTL
(Function code data = 43)
This output signal comes ON when PID control is enabled ("Cancel PID control" (Hz/PID) =
OFF) and a run command is ON. (Refer to the description of J01.)
Motor stopped due to slow flowrate under PID control -- PID-STP
(Function code data = 44)
This output signal comes ON when the inverter is stopped by the slow flowrate stop function
under PID control. (Refer to the descriptions of J15 through J17.)
When PID control is enabled, the inverter may stop due to the slow flowrate stop
function or other reasons, with the PID-CTL signal being ON. As long as the
PID-CTL signal is ON, PID control is effective, so the inverter may abruptl
resume its operation, depending on the PID feedback value.
When PID control is enabled, even if the inverter stops its output during operation because of
sensor signals or other reasons, operation will resume automatically.
Design your machinery so that safety is ensured even in such cases.
Otherwise, an accident could occur.
Switched to motor 2 -- SWM2
(Function code data = 49)
This output signal comes ON when motor 2 is selected with the M2/M1 terminal command
assigned to a digital input terminal. For details, refer to the descriptions of E01 through E03
(Function code data = 12).
Motor overheat detected by thermistor (PTC) -- THM
(Function code data = 56)
When the thermistor is enabled (H26 = 2), this output signal comes ON if the motor
temperature rises to the protection trigger level specified by H27.
Brake signal -- BRKS
(Function code data = 57)
This signal outputs a brake control command that releases or activates the brake. Refer to the
descriptions of J68 through J72.
Terminal [C1] wire break -- C1OFF
(Function code data = 59)
When terminal [C1] is used for a feedback signal under PID control, this output signal comes
ON if the [C1] wire breaks, thereby enabling it to activate the protection function.
Maintenance timer -- MNT
(Function code data = 84)
Once the inverter's cumulative run time or the number of startup times for motor 1 exceeds
the previously specified count, this output signal comes ON.
Refer to H78 and H79.
Frequency arrival detected -- FARFDT
(Function code data = 87)
The FARFDT, which is an ANDed signal of FAR and FDT, comes ON when both signal
conditions are met.
