(RUN) Inverter running
Comes ON when the output frequency is higher than
start frequency.
E20 = 0
(RUN2) Inverter output on
Comes ON when the main circuit (gate) is turned ON.
E20 = 35
(FAR)
Speed/freq.
arrival
Comes ON when the motor speed reaches the set
frequency. (Condition: Run command is ON.)
(Hysteresis width (fixed): 2.5 Hz)
E20 = 1
(FDT)
Speed/freq.
detection
Comes ON when the output frequency is above the
detection level and goes OFF when below the
detection level.
(Hysteresis width (fixed): 1.0 Hz)
E20 = 2
E31
(LU)
undervoltage
detection
Comes ON when the inverter stops its output because
of undervoltage while the run command is ON.
E20 = 3
(IOL)
Inverter output
limit (limit on
current)
Comes ON when the inverter is limiting the current.
E20 = 5
F43, F44
(IPF) Auto-restarting
Comes ON during auto-restarting operation (after
instantaneous power failure and until completion of
restart).
E20 = 6

(OL)
Overload early
warning (for
motor)
Comes ON when the calculated value of electronic
thermal relay is higher than the preset alarm level.

F12
(TRY) Auto-resetting
Comes ON during
auto-resetting mode.

(LIFE) Lifetime alarm
Outputs alarm signal according to the preset lifetime
level.

H42,
H43
(OLP)
Overload
preventive control
Comes ON during inverter control for avoiding
overload.
E20 = 36
H70
(ID) Current detection
Comes ON when a current larger than the set value
has been detected for the timer-set time.
E20 = 37
E34,
E35
(IDL)
Small current
detection
Comes ON when a current smaller than the set value
has been detected for the timer-set time.
E20 = 41
E34,
E35
(ALM)
Alarm relay (for
any fault)
Alarm signal is output as the transistor output signal.
E20 = 99
