Second Acceleration and Deceleration Functions
The SJ100 inverter features two-stage acceleration and deceleration ramps. This gives
flexibility in the profile shape. You can specify the frequency transition point, the point
at which the standard acceleration (F_02) or deceleration (F_03) changes to the second
acceleration (A_92) or deceleration (A_93). These profile options are also available for
the second motor settings. Select a transition frequency method via A_94 as depicted
below. Be careful not to confuse the second acceleration/deceleration settings with
settings for the second motor!
