POWER LOSS START MODE (Parameter P48)
Depending on the start mode function setting, if the run signal is ON and the power is turned

ON or the power is restored after a power failure, the unit may start (restart) suddenly.
(Design the machine so that personal safety can be ensured even if the unit starts suddenly.)
Failure to do so could lead to injury.
Depending on the start mode function setting, if the fault trip is reset with the run signal

present, the unit may restart suddenly.
(Reset the trip after ensuring personal safety.)
Failure to do so could lead to injury.
This parameter sets the starting operation for when an externally set run signal is input when
the power is turned ON.
∗ The factory setting is "1" (OP stop).
∗ When set to "0" : Operation starts immediately when the power is turned ON.

Details of operation
Operation starts immediately when the power is turned ON and the low
voltage level (LU level) is exceeded.
The inverter OP trips when the power is turned ON and the low voltage
level (LU level) is exceeded.
Turn the start input signal OFF once, reset the inverter and then turn the
run signal ON again to resume operation.
The inverter starts when the power is turned ON, the low voltage level
(LU level) is exceeded and the wait time is passed.
(The wait time is set with parameter P50.)
The inverter OP trips when the power is turned ON and the low voltage
level (LU level) is exceeded.
Turn the run signal OFF once, reset the inverter and then turn the run
signal ON again to resume operation.
(This setting will function in the same manner as data "1" if the run
signal is ON when the power is turned ON. However, starting after the
wait time has elapsed is possible during normal startup.)
