n C1-11: Accel/Decel Switch Frequency
Sets the switching frequency for automation accel/decel time change over.
Frequency Level on page 143
No.
C1-11
Note: Setting C1-11 to 0.0 Hz disables this function.
n C1-14: Accel/Decel Rate Frequency
Sets the base frequency used to calculate acceleration and deceleration times.
No.
C1-14
Note: The accel/decel rates set to parameters C1-01 to C1-09 change in response to the value set to C1-14.
When C1-14 = 0.0 Hz
Operation example is shown in
• Accel Times 1 through 4 determine the time required to accelerate from 0 to the maximum output frequency (E1-04)
• Decel Times 1 through 4 and the Fast-stop Time determine the time required to decelerate from the Maximum Output
Frequency (E1-04) to 0 Hz.
E1-04 = 60 Hz
Frequency
reference = 60 Hz

When C1-14 ≠ 0.0 Hz
Operation examples are shown in
• Accel Times 1 through 4 determine the time required to accelerate from 0 to the value set in C1-14 (Accel/Decel Rate
Frequency)
• Decel Times 1 through 4 and the Fast-stop Time determine the time required to decelerate from the value set in C1-14
(Accel/Decel Rate Frequency ) to 0 Hz.

reference = 60 Hz
C1-14 = 40 Hz
