Speed Search Mode Selection
Range
【0】:Disable
【1】:Execute speed search once
【2】:Speed Search Start
0:The inverter start to run from the lowest output frequency but it won’t limit the other
functions of trigger speed search.
1:The inverter executes a speed search at power on when entering first run command.
It start the motor from found frequency.
2:The speed search function is performed every time when the run command in input.
Notes:
When 00-00=5 (PMSLV control mod), Frame1 and Frame2 without this function.
07- 13 Low voltage detection level
Range
【200V Class:150~300V】
【400V Class:250~600V】
07- 25
Low voltage detection time
Range
【0.00~1.00】Sec
Adjust the 07-13 voltage level from 150 to 300 Vdc (200V class) or from250 to 600 Vdc
(400V class).
When the AC input voltage is lower than the 07-13 value (07-13/ 1.414 = AC voltage
detection level) for the time specified in 07-25 the low-voltage error "UV" will
displayed. If 07-25 = 0.00 sec., the UV error will be displayed immediately.
Set preventive measures:
①. The inverter input voltage will limit the output voltage. If the input voltage drops
excessively, or if the load is too big, the motor may stall.
②. If the input voltage drops below the value set in 07-13 then the output is turned off
momentarily. The inverter will not automatically start when power is restored.
07- 18
Minimum base block time
Range
【0.1~5.0】Sec
In case of a momentary power failure, the inverter continues to operate after the power has
been restored when parameter 07-00 is set to 1.
Once the momentary power failure is detected; the inverter will automatically shut
down the output and maintain B.B for a set time (07-18).
When the momentary power failure time exceeds the minimum base block time
(07-18), the inverter will automatically perform a speed search upon return of power.
