When one of those parameters is set to a value between 600.1 s and 1000.0 s, you can set C1-10 = 0, but the time will
change to 600.00 s.
1 : 0.1 s (0.0 to 6000.0 s)
Sets acceleration and deceleration times in 0.1 s units. The setting range is 0.0 to 6000.0 s.

C1-11 Accel/Decel Time Switching
Frequency
(020A)
When the output frequency is at the C1-11 value, the drive automatically switches the acceleration and deceleration
times. Set this parameter to 0.0 to disable this function.
Table 12.31 lists the possible combinations of acceleration and deceleration time switchover frequencies and the
acceleration times for the Motor 2 Selection function.

RUN
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
Output Frequency]
– 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.
