Check result
Action
10 Undervoltage
The voltage of the
control circuit
power supply has
dropped.
(1) The control circuit
power supply wiring is
incorrect.
Check the control
circuit power supply
wiring.
It has a failure.
Wire it correctly.
It has no failure.
Check (2).
(2) The voltage of the
control circuit power
supply is low.
Check if the voltage of
the control circuit
power supply is lower
than prescribed value.
200 V class: 160 V AC
400 V class: 280 V AC
The voltage is the
prescribed value or
lower.
Review the voltage
of the control circuit
power supply.
The voltage is
higher than the
prescribed value.
Check (3).
(3) An instantaneous power
failure has occurred for
more than 60 ms.
Check if the power
has a problem.
It has a problem.
Review the power.
It does not have a
problem.
Check (4).
(4) Failure of the part in
the resistance
regeneration converter
unit.
Disconnect the cables
except for the control
circuit power supply,
and then check the
repeatability.
It is repeatable.
Replace the
resistance
regeneration
converter unit.
12 Memory error 1
(RAM)
Failure of the part
(RAM) in the
resistance
regeneration
converter unit.
(1) Failure of the part in
the resistance
regeneration converter
unit.
Disconnect the cables
except for the control
circuit power supply,
and then check the
repeatability.
It is repeatable.
Replace the
resistance
regeneration
converter unit.
It is not repeatable.
Check (2).
(2) Something near the
device caused it.
Check the power
supply for noise.
It has a failure.
Take
countermeasures
against its cause.
15 Memory error 2
(EEP-ROM)
Failure of the part
(EEP-ROM) in the
resistance
regeneration
converter unit.
(1) EEP-ROM
is
malfunctioning at power
on.
Disconnect the cables
except for the control
circuit power supply,
and then check the
repeatability.
It is repeatable.
Replace the
resistance
regeneration
converter unit.
It is not repeatable.
Check (2).
(2) The number of write
times to EEP-ROM
exceeded 100,000.
Check if parameters
have been used very
frequently.
It was changed.
Replace the
resistance
regeneration
converter unit.
Change the process
to use parameters
less frequently after
replacement.
It was not changed. Check (3).
(3)
EEP-ROM
is
malfunctioning during
normal operation.
Check if the error
occurs when you
change parameters
during normal
operation.
It occurs.
Replace the
resistance
regeneration
converter unit.
It does not occur.
Check (4).
(4) Something near the
device caused it.
Check the power
supply for noise.
Check if the connector
is shorted.
It has a failure.
Take
countermeasures
against its cause.
17 Board
error
A part in the
resistance
regeneration
converter unit is
malfunctioning.
(1) The
resistance
regeneration converter
unit recognition signal
was not read properly.
Disconnect the cables
except for the control
circuit power supply,
and then check the
repeatability.
It is repeatable.
Replace the
resistance
regeneration
converter unit.
It is not repeatable.
Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take
countermeasures
against its cause.
