Cooling fan operating selection (b011)
You can select whether the fan operates continuously or operates only when the inverter is in the
running operation.

Ground Fault selection (b013)
(1) This is the function to warn when ground fault is occurred.
(2) Note that if this code is 1(valid) only the moment when the power is on, the inverter checks
out ground fault between the inverter output and the motor.
(3) If ground fault is detected while running, inverter will stop with another error(overcurrent /
overvoltage etc).

Initialization selection (b014)
(1) It is possible at any time to reinitialize the inverter parameters back to the factory default.
(2) The trip history can also be cleared at any time, however, if problems occur it will be difficult to
find fault without the trip history for reference.
(3) RUN time, ON time is not cleared.
