C1-11 Ac/Dec Switch Frequency
(020A)
When output frequency get C1-11 value, the drive automatically switches the acceleration and deceleration times.
Set this parameter to 0.0 to disable this function.
Table 12.17 lists the possible combinations of acceleration and deceleration time switchover frequencies and the
acceleration times for the Motor 2 Selection function.

C1-14 Ac/Dec Base Frequency
(0264)
The acceleration and deceleration rates set in C1-01 to C1-09 [Accel Time 1 to Decel Time 4, Fast Stop Time] will
change when the value of C1-14 changes.
• When C1-14 = 0.0 Hz
– C1-01, C1-03, C1-05, C1-07 [Accel Time 1 to Accel Time 4]: Time to accelerate from 0 Hz to E1-04 [Max
Output Frequency]
– C1-02, C1-04, C1-06, C1-08 [Decel Time 1 to Decel Time 4], C1-09 [Fast Stop Time]: Time to decelerate
from E1-04 to 0 Hz.
