* To switch to 2nd/3rd acceleration time 1 or 2nd/3rd deceleration time 1, allocate 08 (SET)/17 (SET3) to the
desired multi-function input and then turn it on.
• The set time here indicates the acceleration/deceleration time from 0 Hz to the maximum
frequency.
• When the LAD cancel (LAC) function is selected in the multi-function input selection and the signal
is turned on, the acceleration/deceleration time is ignored, and the output frequency
instantaneously follows the reference frequency.
• To switch between the 1st/2nd/3rd acceleration times or between the 1st/2nd/3rd deceleration
times, allocate 08 (SET)/17 (SET3) to the desired multi-function input (refer to "Multi-function Input
Selection" (page 4-77)), and use the SET/SET3.
• You can set the acceleration/deceleration time via (1) the Digital Operator, (2) optional board 1, or
(3) optional board 2.
• Even if a short acceleration/deceleration time is set, the actual time cannot be shorter than the
minimum acceleration/deceleration time that is determined by the mechanical inertia moment and
the motor torque. If you set a time shorter than the minimum time, an overcurrent/overvoltage trip
may occur.
For short-time deceleration, use a braking unit (optional).
