The MX2 inverter features two-stage acceleration and deceleration ramps.
This gives flexibility in the profile shape. You can specify the frequency transi-
tion point, the point at which the standard acceleration (
F003
( ) changes to the second acceleration (
you can use intelligent input [2CH] to trigger this transition. These profile
options are also available for the second motor settings. Select a transition

Dec1 time (less than 1.0 second), the inverter may not be able to change
rates to Acc2 or Dec2 before reaching the target frequency. In that case, the
inverter decreases the rate of Acc1 or Dec1 in order to achieve the second
ramp to the target frequency.
