*1 Default value changes when o2-04 [Drive Model (KVA) Selection] and C6-01 [Normal / Heavy Duty Selection] values change.
*2 Default value changes when o2-04 [Drive Model (KVA) Selection] value changes.
*3 Refer to the section on C5-xx parameters for more information about speed control (ASR).
*4 The best values for a no-load operation are different than the best values for actual loading operation.
