Second Acceleration and Deceleration Functions
The X200 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 (F002) or deceleration (F003) changes to the second
acceleration (A092) or deceleration (A093). Or, you can use intelligent input [2CH] to
trigger this transition. These profile options are also available for the second motor
settings. Select a transition method via A094 as depicted below. Be careful not to
