8.21.2 Trip check
1 . Turn on the instrument breaker.
2 . Press [DATA SET] on the inverter control panel once. The parameter No. indicator blinks (2-
digit LED).
3 . Press
or
to display the parameter No. 81 to 85 of which setting is to be confirmed.
4 .
Check the 5-digit LED indication.
Parameter No. 81 is the most recent trip code. The trip record becomes older in
the order of 82, 83, 84, and 85.

Protective function
Details of protection
Monitor (blinking)
Electric thermal operation
When the output current reaches the electric thermal
level and the timer operates, the indication on the
monitor blinks.
L
Under voltage warning
instantaneous blackout
When the converter is for AC 200 V (AC 100 V), DC 200
V (DC 100 V) or less is taken as instantaneous blackout
and the inverter power output is stopped. In addition, for
the converter for AC 200 V, the control circuit is reset
when the voltage becomes DC 75 V or less.
If the voltage recovers before the control circuit is reset,
the instrument can restart the operation automatically.
┌
.P.
Restart prevention after power
restoration
When power restores from instantaneous blackout
during operation, automatic restart is prevented if
operation command was given, and the circuit breaker
is tripped.
However, this function does not work if the control circuit
is reset.
0.C.
Overcurrent protection
If the output current of the converter exceeds the set
current of each inverter, the circuit breaker is tripped.
0.C.-U
If the output current of the converter exceeds the set
current of each inverter during acceleration, the circuit
breaker is tripped.
0.C.-d
If the output current of the converter exceeds the
current set to each inverter during deceleration, the
circuit breaker is tripped.
0.C.-C
If the value detected by the current sensor exceeds the
set current of each inverter, the circuit breaker is
tripped.
0.U.
Regenerative overvoltage
protection
When direct current to the converter for AC 200 V (AC
100 V) increases and exceeds DC 400 V (DC 200 V),
the circuit breaker is tripped.
ГH ┌
Overload protection function
(electric thermal)
If the current to the motor flows continuously beyond the
rated load current, it is taken as overload and the circuit
breaker is tripped.
While the current flows, a 5-digit LED blinks.
0.H.
Radiation fin overheat protection
If the radiation fin is overheated, the thermal sensor
functions and the circuit breaker is tripped.
E..-0.S.
Overspeed protection
If the rotation number exceeds 1.5 times the maximum
speed, it is taken as overspeed and the circuit breaker is
tripped.
E..‑C.S.
Sensor abnormality protection
When the abnormality of the CS signal is detected, the
circuit breaker is tripped.
E ┌┌
CPU error
If the failure of the controlling microcomputer is
detected, the circuit breaker is tripped.
