This parameter moves to a fundamental parameter. *1: Default values vary depending on the capacity.  See the table of K-48.
*2: Changing the parameter  enables to set to 0.01 sec. (adjustment range: 0.01~600.0 sec.).
*3: Although the setting can be written into memory if  is set to  (power ride-through control), it cannot be written if  is set to  (deceleration stop during a power failure).
*4: is available for VFAS1-2550P, VFAS1-4900PC and above.
