POWER LOSS START MODE (Parameter P48)
CAUTION
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.
∗ When set to "2" : Operation starts after the wait time has elapsed after the power is
