• C1-01 to C1-09
• L2-06
• L2-07
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 Switchover Freq
No.
(Hex.)
Name Description
Default
(Range)
C1-11
(020A)
Accel/Decel Time
Switchover Freq
Sets the frequency at which the drive will automatically change acceleration
and deceleration times.
Determined by A1-02
(0.0 - 590.0 Hz)
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.
Figure 11.47 Accel/Decel Time Switching Frequency
Table 11.36 lists the possible combinations of acceleration and deceleration time switchover frequencies and the
acceleration times for the Motor 2 Selection function.

■ C1-14: Accel/Decel Rate Frequency
No.
(Hex.)
Name Description
Default
(Range)
C1-14
(0264)
Accel/Decel Rate
Frequency
Sets the base frequency used to calculate acceleration and deceleration rates.
0.0 Hz
(0.0 - 590.0 Hz)
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.
