3.6 C: Tuning
◆ C1: Accel & Decel Time
No.
(Hex.)
Name Description
Default
(Range)
C1-01
(0200)
RUN
Acceleration Time 1 Sets the length of time to accelerate from zero to maximum output frequency. 10.0 s
(0.0 - 6000.0 s)
C1-02
(0201)
RUN
Deceleration Time 1 Sets the length of time to decelerate from maximum output frequency to zero. 10.0 s
(0.0 - 6000.0 s)
C1-03
(0202)
RUN
Acceleration Time 2 Sets the length of time to accelerate from zero to maximum output frequency. 10.0 s
(0.0 - 6000.0 s)
C1-04
(0203)
RUN
Deceleration Time 2 Sets the length of time to decelerate from maximum output frequency to zero. 10.0 s
(0.0 - 6000.0 s)
C1-05
(0204)
RUN
Acceleration Time 3 Sets the length of time to accelerate from zero to maximum output frequency. 10.0 s
(0.0 - 6000.0 s)
C1-06
(0205)
RUN
Deceleration Time 3 Sets the length of time to decelerate from maximum output frequency to zero. 10.0 s
(0.0 - 6000.0 s)
C1-07
(0206)
RUN
Acceleration Time 4 Sets the length of time to accelerate from zero to maximum output frequency. 10.0 s
(0.0 - 6000.0 s)
C1-08
(0207)
RUN
Deceleration Time 4 Sets the length of time to decelerate from maximum output frequency to zero. 10.0 s
(0.0 - 6000.0 s)
C1-09
(0208)
RUN
Fast Stop Time Sets the length of time that the drive will decelerate to zero for a 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.
• 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 Tuning.
