12.4 C: Tuning
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 12.37 lists the possible combinations of acceleration and deceleration time switchover frequencies and the
acceleration times for the Motor 2 Selection function.

The acceleration and deceleration rates set in C1-01 to C1-09 [Acceleration/Deceleration Times 1 to 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 [Acceleration Times 1 to 4]: Time to accelerate from 0 Hz to E1-04 [Maximum

– C1-02, C1-04, C1-06, C1-08 [Deceleration Times 1 to 4], C1-09 [Fast Stop Time]: Time to decelerate from
E1-04 to 0 Hz.
