(RUN) Inverter running Comes ON when the output frequency is higher than
starting 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
F14
(OL) Overload early
warning (for
motor)
Comes ON when the calculated value of electronic
thermal relay is higher than the preset alarm level.

(OLP) Overload
preventive control
Comes ON during inverter control for avoiding
overload.

detection
Comes ON when a current smaller than the set value
has been detected for the timer-set time.

(ALM) Alarm relay (for
any fault)
Alarm signal is output as the transistor output signal. E20 =
