Capability to view and set specific parameters is dependent upon the Access Level (A1-01) and Control Method (A1-
02: 0 = V/f, 1 = V/f w/PG, 2 = Open Loop Vector, 3 = Flux Vector) the drive is programmed for. Each column represents
the minimum Access Level for a given Control Method: 0 = Operation only; Q = Quick-start; B = Basic; A = Advanced; - =
not available.
