C1-07: Acceleration Time 4
No.
Name
(Hex.)
C1-07 Acceleration Time 4
(0206)
RUN
Note:
When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)], the setting range is 0.00 to 600.00 s.
■
C1-08: Deceleration Time 4
No.
Name
(Hex.)
C1-08 Deceleration Time 4
(0207)
RUN
Note:
When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)], the setting range is 0.00 to 600.00 s.
■
C1-09: Fast Stop Time
No.
Name
(Hex.)
C1-09 Fast Stop Time
(0208)
RUN
Note:
• When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)], the setting range is 0.00 to 600.00 s.
• When L2-29 = 0 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 1] and you do KEB Auto-Tuning, the drive will
automatically set C1-09. If you must not change the Fast Stop time, do not do KEB Auto-Tuning.
The Fast Stop function will be triggered in the following circumstances.
• The Fast Stop operation will be triggered by the input of the Fast Stop command via the multi-function digital input
terminal.
• The Fast Stop operation is will be triggered when by the input of the Fast Stop command is input via the multi-
function digital input terminal.
Set H1-xx = 15, 17 [MFDI Function Select = Fast Stop (N.O.), Fast Stop (N.C.)].
When the Fast Stop command is input, the Fast Stop operation will be triggered at the deceleration time set to C1-09.
The drive cannot be restarted after initiating a Fast Stop operation until deceleration is complete. Complete
deceleration and cycle the Run command to clear the Fast Stop input.
The terminal set for H2-xx = 4C [MFDO Function Select = During Fast Stop] will be ON during Fast Stop.
Note:
Decelerating too quickly can cause an ov [Overvoltage] fault that shuts off the drive while the motor to coasts to a stop. Set a Fast Stop time
in C1-09 that prevents motor coasting and makes sure that the motor stops quickly and safely.

C1-10: Accel/Decel Time Setting Units
No.
Name
(Hex.)
C1-10 Accel/Decel Time Setting
Units
(0209)
0 : 0.01 s (0.00 to 600.00 s)
Sets acceleration and deceleration times in 0.01 s units. The setting range is 0.0 to 6000.0 s.
If one of these parameters is set to 1000.0 s or longer, you cannot set C1-10 = 0:
• C1-01 to C1-09

V/f CL-V/f OLV CLV AOLV
Sets the length of time to accelerate from zero to maximum output frequency.
V/f CL-V/f OLV CLV AOLV
Sets the length of time to decelerate from maximum output frequency to zero.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will decelerate to zero for a Fast Stop.
V/f CL-V/f OLV CLV AOLV
Sets the setting units for C1-01 to C1-08 [Accel/Decel Times 1 to 4], C1-09 [Fast Stop Time], L2-06
[Kinetic Energy Backup Decel Time], and L2-07 [Kinetic Energy Backup Accel Time].
