0.0 Hz
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.
