User Manual of A90 Series Inverter Output frequency Output frequency (Hz) Fbase (Hz) Fbase Time Time (s) t2 (s) (a) Acceleration time 1 (b) Deceleration time 1 t1 Fig. 7-4 Acceleration and Deceleration Time Note that the acceleration and deceleration time is in 0.01 s, 0.1 s or 1s, depending on the F15.13. The allowable maximum frequency of the inverter is represented by Fmax. The Fmax range is from 20.00 to 600.00Hz. F00.17=0: set by F00.18 The upper frequency limit is set by F00.18.
