Tips/FAQ/Troubleshooting
E016 Instantaneous power
failure error
At the time of an instantaneous power failure, the
inverter turns OFF its output. If the power failure
continues, the event is regarded as a normal
power-off.
Decrease in the main power R, S, or T generates
this error. Decrease in the voltage of control circuit
power supply R0 or T0 doesn’t generate the error if
the J51 connector has been removed and the R0
and T0 are input via a separate system.
E019 Temperature detector
error
This error occurs if there is a problem in the
temperature detector circuit such as disconnection.
E016
Occurrence

Estimated cause(s)

Exemplar measures to be taken
Error occurred with
the start of
operation.
• PS voltage decreased.
• If an instantaneous power failure hasn’t occurred, insufficient
capacity of power supply may be the cause. Re-examination of the
power supply environment is required.
Error occurred
after long hours of
use.
• PS voltage decreased.
• If the power is turned OFF due to an external factor such as power
failure, the inverter can be restarted by using the retry function when
the power is restored.
• There was a contact fault
in circuit breaker.
• Failure of magnetic contactor or earth-leakage breaker may be the
cause.
Although the inverter may recover, a repair is required.
E019
Occurrence

Estimated cause(s)

Exemplar measures to be taken
Error occurred after
use.
• The temperature
detector circuit is
disconnected or broken
down.
• The temperature detector circuit is broken down. A repair is
required.
