E024 Input open-phase
error
When [bb-65] input phase loss selection is set to 01,
when a missing phase is detected in input line, the
inverter turns OFF its output.
E030 IGBT error
At the time of an instantaneous overcurrent or the
main element failure, the inverter turns OFF its output
to protect the main element.
Overcurrent error may be issued instead.
Error occurred after
long hours of use.
• An input line or breaker
has a loose connection
or is disconnected.
• The situation may be improved by mending loose connections due
to loosening of screws or the breaker problems.

Exemplar measures to be taken
Error occurred
right after the
operation started.
• A ground fault has
occurred.
• Output line is
short-circuited.
• After the power is turned OFF, you need to check the wires
connected to the motor, motor disconnection, and the like.
If the
error occurs after removal of the motor wires, the inverter is broken
down. It needs to be repaired.
• Motor rotation is locked.
• A large current may flow when the motor rotation is locked during
operation. The cause needs to be removed.
• Output element is broken
down.
• If output element is broken down, it needs to be repaired.
Error occurred right
after power was
turned ON.
• Output element is broken
down.
• If output element is broken down, it needs to be repaired.
Error occurred
during operation.
• Motor rotation is locked.
• A large current may flow when the motor rotation is locked during
operation. The cause needs to be removed.
E024
Error occurred
after power was
turned ON.
• An input line or the
motor has a loose
connection or is
disconnected.
• You need to turn OFF the power supply and check the input lines
and the wiring condition of breaker.
This error may also occur due to
PS voltage defect, contact defect, screw tightening failure, etc.
• Single-phase input is
used.
• For input lines, use three-phase connection.
