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.
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.
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.
Alarm output (for any alarm) --
ALM
(Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter
enters Alarm mode.
E30
Frequency Arrival (Hysteresis width for
FAR
)
E30 specifies the detection level (hysteresis width) for
FAR
("Frequency arrival signal").
The moment the output frequency reaches the zone defined by "Reference frequency
±
Hysteresis width specified by E30," the
FAR
comes ON.
The operation timings of signals are shown in the graph below.
E34, E35
Overload Early Warning/Low Current Detection (Level and Timer)
E37, E38
Current Detection 2 (Level and Timer)
These function codes define the detection level and timer for the
OL
("Motor overload early warning"),
ID
("Current detected"),
ID2
("Current detected 2") and
IDL
("Low current detected") output signals.
