Functions
The L300P inverter features two-stage acceleration and deceleration ramps. This gives flexibil-
ity 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). These profile options are also available for the second motor settings
and third motor settings. All acceleration and deceleration times are time to ramp from zero
speed to full speed or full speed to zero speed. 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!
