No.
C1-09
<1> The setting range for the acceleration and deceleration times is determined by C1-10 (Accel/Decel Time Setting Units). For example, if the time is
set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s
NOTICE: Rapid deceleration can trigger an overvoltage fault. When faulted, the drive output shuts off, and the motor coasts. To avoid this
uncontrolled motor state and to ensure that the motor stops quickly and safely, set an appropriate Fast-stop time to C1-09.
C1-10: Accel/Decel Time Setting Units
n
Determines the units for the acceleration and deceleration times set to C1-01 through C1-09 using parameter C1-10.
No.
C1-10
Setting 0: 0.01 s Units
The accel/decel. times are set in 0.01 s units. The setting range will be 0.00 to 600.00 s. If any of the parameters C1-01 to
C1-09 is set to 600.1 seconds or more, then C1-10 cannot be set to 0.
Setting 1: 0.1 s Units
The accel/decel. times are set in 0.1 s units. The setting range will be 0.0 to 6000.0 s.
C1-11: Accel/Decel Switch Frequency
n
Sets the switching frequency for automation accel/decel time change over.
No.
C1-11
Note:
Setting C1-11 to 0.0 Hz disables this function.
C1-14: Accel/Decel Rate Frequency
n
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
