6-7 Acceleration/Deceleration Settings
Set up the acceleration time and the deceleration time of the motor. Set a longer time for slower accel-
eration or deceleration; set a shorter time for faster acceleration or deceleration.
As for the acceleration time, set the time that it takes to rise from 0 Hz to the maximum frequency; as for
the deceleration time, set the time that it takes to fall from the maximum frequency to 0 Hz.
In the initial state, the acceleration time setting 1, 1st-motor [AC120] and the deceleration time setting
1, 1st-motor [AC122] are enabled.
The currently enabled acceleration time and deceleration time can be monitored with [FA-10] and
[FA-12], respectively; In the initial state, [FA-10] = [AC120] acceleration time 1 and [FA-12] = [AC122]
deceleration time 1
Precautions for Correct Use
• When the function of acceleration or deceleration action cancellation 071 [LAC] is selected
as the Input terminal function and the signal is turned ON, the set acceleration or decelera-
tion time will be reset to 0 seconds and the output frequency will be made instantaneously to
follow the frequency command.
• The target of command for the acceleration or deceleration time can be selected with
[AC-01].
• Employ the internally-set acceleration or deceleration time.
• Employ the acceleration or deceleration time of the program function Drive Programming.
• The acceleration or deceleration time may be changed in response to the command given by
the multi-speed function. For details, see 6-4-9 Case where Command Is Given with
Multi-Step Speed on page 6-37.
