 The Acceleration Time determines the time required for the AC motor drive to ramp from 0.00
Hz to the Maximum Output Frequency (Pr.01-00). The Deceleration Time determines the
time required for the AC motor drive to decelerate from the Maximum Output Frequency
(Pr.01-00) down to 0.00 Hz.
 Select the Acceleration/Deceleration Time 1, 2, 3, 4 with the multi-
function input terminal
settings. The defaults are Acceleration Time 1 and Deceleration Time 1.
 When there is a large opposing torque and inertial torque for the load, and the acceleration
and deceleration time settings are less than the necessary value, then they enable the torque
limit and stall prevention functions. When this happens, the actual acceleration and
deceleration time are longer than the settings.
