Functional Descriptions (By Parameter No.)

POWER LOSS START MODE (Parameter No. 50)

ATTENTION

Depending on the start mode function settings, 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 personnel 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.
* 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 is passed after the power is turned on.)

Used to select the start mode when the power supply is turned ON and the run signal is input.

Data setting value	Outline operation	Details of operation
0	Run	Operation starts immediately when the power is turned ON and the low voltage level (LU Level) is exceeded.
1	"OP" stop	The inverter OP trips when the power is turned ON and the low voltage level (UL level) is exceeded. Turn the run signal ODD once, reset the inverter and then turn the run signal On again to resume operation.
2	Operate after wait time	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 No. 52)
3	"OP" stop	The inverter OP trips when the power is turned ON and the low voltage level (LU level) is exceeded. Turn the run signal On again to resume operation. * When this data is set, the same operation as data setting value "1" will occur when the run signal is input after the power is turned ON, however , the wait time will be waited for during normal starting.
