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 confuse the second acceleration/deceleration settings with settings for the second motor!
