L2-02
Momentary power loss ride thru time
This setting is valid only when constant l2-01 is set to 1. Set the power loss ride thru time in seconds.
Note : the factory setting depends on the inverter,s capacity . it is the momentary power loss ride thru time when l2-01 is set to be 1.

Min base block time
To set the time base block time in unit of seconds when the inverter restarts after momentary power loss.
Note : the factory setting depend on inverter capacity this setting is used with the speed search and dc injection braking function. Set the time required for the leakage voltage to dissipate. Increase the setting if an over current (0c) occurs when the speed search or dc injection braking function starts. This setting is valid for speed searches after a momentary power loss regular speed searches.

Voltage recovery time
Set the time allowed for the normal voltage to be restored after completion of the speed search . the unit is seconds .
Note : this is the time in seconds for voltage to be restored from 0v ac to 400v ac after set speed researching is finished . this setting is valid for speed searches after a momentary power loss regular speed searches the voltage changes with energy saving control and voltage changes with base block clearing.

Under voltage detection level
Detection level of main circuit low voltage (main circuit dc voltage ) it is in unit of voltage.
Note : setting range and the factory default is 400 volt to set normally it is not necessary to change the setting use this constant when you want to add an ac reactor and lower the main circuit under voltage detection level be sure to set a main circuit dc voltage value voltage that will detect a main circuit under voltage .
